Absolute Black Race Face Oval Cinch Boost Direct Mount Traction Chainring Absolute Black Race Face Oval Cinch Boost Direct Mount Traction Chainring
Absolute Black is one of the leaders in the oval ring market because it leaves no stone--or crank, in this case--unturned. The Race Face Oval Cinch Boost Direct Mount Traction Chainring's very specialized application proves this assertion: its offset and direct-mount design work with a Cinch crank mounted on a Boost frame. This makes installation comically easy and lets you get straight to the chainring's raison d'etre, which is reducing the dead spot in your pedal stroke to reanimate lost watts. By reducing that dead spot, Oval Traction Chainrings boost traction by essentially spreading the power input load more evenly across the pedal stroke. Keeping power constant lets your tire exert a steady force on the trail, so there are fewer instances of slipping out in wet or mucky conditions. The ring shape also spreads the work your body is doing more evenly across the different muscle groups involved, which means less strain on your biological machine, too.

Absolute Black SRAM Oval Direct Mount Traction Chainring Absolute Black SRAM Oval Direct Mount Traction Chainring
Round chainrings are standard because, well, they're standard, but they don't actually match the changing power output of your legs through a pedal stroke. Absolute Black's SRAM Oval Direct Mount Traction Chainring's oblong shape makes pedaling easier in hard spots and steadier in easy spots, so you can keep a constant and smooth cadence without having to deal with dead up-strokes and leg-crushing down-strokes. This makes it easier to nail down the highly efficient circular pedaling motion that's we're all after, and improves traction by eliminating the wheel slip that happens during hard down-strokes on loose terrain. If you're going to make a killer chainring, you might as well pull out all the stops, so Absolute Black also machined this aluminum-alloy beauty with a narrow-wide tooth profile and 3D design that improves chain retention, sheds mud, and reduces wear and noise. It also engineered the Oval to mount directly to almost all SRAM cranksets, so you can eliminate the extra weight of a spider, which will be a boon to your quads when you're hammering up steep dirt and across fast sections of rolling singletrack. Run the 0mm offset models with a short spindle BB30 cranks and the 6mm offset with the standard BB30 spindle. The easiest way to identify which spindle you have is by checking the width of the spacer between the chainring and the bottom bracket shell. the short spindle has a 9mm spacer while the long or standard spindle has a 15mm spacer.

Campagnolo Chorus 11 4-Arm Crankset Campagnolo Chorus 11 4-Arm Crankset
Completely redesigned for the release of Campy's new mechanical groupsets, the Campagnolo Chorus 11 4-Arm Crankset showcases a number of significant improvements. The new crank is visually striking, but the changes weren't intended to be cosmetic alone. The new crank's 4-arm bolt pattern allows for the installation of any of Campagnolo's chainring combinations -- 50/34, 52/36, or 53/39 -- without the need to swap out the entire crank, which was necessary with the old design. Along the way, Campagnolo shaved weight while boosting rigidity, placing the new Chorus 11 crankset on a level of stiffness that eclipses even the stiffest of Campy's last-generation cranks. The Campagnolo Chorus 11 4-Arm Crankset is available in 170mm, 172. 5mm, and 175mm crankarm lengths, and with 50/34-, 52/36-, or 53/39-tooth chainring combinations.

Campagnolo Record 11 4-Arm Crankset Campagnolo Record 11 4-Arm Crankset
If we had to choose our favorite piece from Campagnolo's new Record groupset -- and the biggest key to its historical success -- we wouldn't go for the obvious, high-profile shift levers or derailleurs. Instead, we'd point at the radically redesigned Record 11 4-Arm Crankset. This is because, though there are huge changes to its external design, Campagnolo still builds the crankset's internals around the virtually perfect USB (Ultra Smooth Bearings) technology. USB uses the same ceramic ball bearings as Super Record crankset's CULT bearings, only sacrificing smoothness and durability by not including Super Record's Cronitect races. Of course, for us mere mortals, the minute difference in longevity and friction are nearly impossible to identify. If every possible watt over the course of a 21 day grand tour matters, then you may prefer Super Record; otherwise, USB's 50% gain in efficiency over Chorus's steel bearings will likely be more than fast enough. Externally, the big, obvious changes are in the crank arms and chainrings. The crank arms lost a longtime comrade when their number fell to four, which nets a claimed 12% gain in torsional stiffness. They also lost a bit of metal, replacing it with lighter, stiffer carbon that extends all the way to the big ring. Like their predecessors, the new Record crank arms are strategically hollowed in areas that don't need the extra reinforcement in order to reduce weight compared to the new Chorus model, which is only hollow on the non-drive side. Instead of sharing one set of five chain ring coupling holes, both rings now get the benefit of their own set. This effectively standardizes the crankset's bolt circle diameter and lets you switch from compact to standard rings without swapping the entire unit. The full-size rings have eight pins with corresponding up- and downshift zones for immediate shifting engagement, while the semi-compact and compact rings have four pins. All three options are also more aerodynamic, ...

Campagnolo Super Record 11 4-Arm Crankset Campagnolo Super Record 11 4-Arm Crankset
Life is short, and you only get one shot at it, so you shouldn't waste time riding outdated, sticky, or heavy cranksets. Enter the Campagnolo Super Record 11 4-Arm Crankset, a redesigned legend that's coming back even lighter, stronger, and sleeker than past iterations. A few major changes set the new Super Record apart from its predecessor. Most obviously, the number of arms was reduced from five to four, which Campagnolo claims reduces weight while increasing torsional stiffness up to 12%. Certain areas of the arms have also seen metal swapped out in favor of carbon, and Campy also hollowed out the new arms as much as possible to reduce weight. The Super Record isn't totally redesigned, though--why would it be' The light, powerful, and super-simple Ultra Torque spindle is just as good as ever, and the titanium spindle and bolt save 40g over the steel used in the regular Record. Even better, Campagnolo's legendary CULT ceramic bearings and Cronitect races are so smooth that Campy claims a 3. 5 watt gain per pedal stroke.

Easton EC90 SL Crankset Easton EC90 SL Crankset
With the recent merger of Easton and Race Face, the former was able to bring the latter's future-proof Cinch crankset technology from mountain bikes to road, cyclocross, and gravel. We built the direct-mount, one-by Easton EC90 SL Crankset primarily for 'cross and gravel, but the crank arms' modularity means it can adapt to the spider-life of a double as needed. That modularity is the key to the crankset's future-proof status. Rather than being adrift in an ever-expanding sea of proprietary standards and slightly tweaked dimensions, the self-sponsored cyclist can invest once in the Cinch-equipped EC90 SL crank system with confidence that, regardless of what the future holds, the chassis will be compatible. The crank arms themselves are Easton's EC90 SL carbon fiber, a material that's already been proven from cockpit components to the soles of some of cycling's most popular race shoes. The included rings say "Easton," but they feature a narrow/wide tooth profile similar to the one-by standouts from Race Face, so the chainring clears debris caked-on from peanut-butter mud pits and maintains chain retention across washboard and over-sized gravel.

Osymetric O-14 4 Arm Chainring 110mm BCD Osymetric O-14 4 Arm Chainring 110mm BCD
With the introduction of testing power and measuring exact watts created in various phases of the pedal stroke, cyclists have been looking for ways to reap every watt possible out of every degree. Osymetric has the latest theory in how to transfer the most power from your legs to the drivetrain with its dual-cam-designed chainrings. Essentially, even though cyclists are taught to "round out" their pedal strokes, very few actually are able to fully execute it well. And while an ovalized ring maximizes power for part of the stroke, the dual-cam more effectively minimizes the dead spot in the pedal stroke. The Osymetric chainring is the brainchild of French engineer Jean-Louis Talo. The radically-shaped chainrings use a dual-cam design, with each cam lobe corresponding to the most powerful part of the pedal stroke: the downstroke. The design increases the gear inches of the chainring at the point where you're able to apply the most force, but as you transition to your least powerful part of the stroke, or dead spot, the chainring reduces in size to speed you back into the power part of the stroke. For instance, an Osymetric 52-tooth chainring would be similar to a 55-tooth in the largest portion of the cam, then gradually reducing to a 49-tooth over the dead spot. This translates to a claimed 3% increase in speed. As a note, to install the chainrings, you'll need to make adjustments to the derailleur height and width with the included screw. And you'll also need to spend time fine tuning the rear derailleur. The first ride may seem a bit awkward, but after a few times out you'll feel more power in your stroke and be less aware of any inconsistencies in chainring shape. The O-14 is for the new four-arm Shimano Dura-Ace and Ultegra cranksets. They are available as small and large chainrings in 38t, 42t, 50t, 52t, and 54t.

Osymetric O-14 5-Arm Chainring 130mm BCD Osymetric O-14 5-Arm Chainring 130mm BCD
One of the key ways to maximize power to the drivetrain is to learn to pedal efficiently, or to not pedal in "squares." The most powerful pedal strokes have equal pressure applied to the pedals throughout the entire 360 degrees. Osymetric recognized that the perfect pedal stroke is difficult for even the most skilled professional to perform, so its dual cam chainrings were designed to address the deficiencies in pedal stroke. The first thing you'll notice about the chainring is that it has an odd shape. The Osymetric chainring is the brainchild of French engineer Jean-Louis Talo. The chainrings use a dual-cam design, with each cam lobe corresponding to the most powerful part of the pedal stroke: the downstroke. This gives it the unmistakable square/oblong shape. The design increases the gear inches of the chainring at the point where you're able to apply the most force, but as you transition to your least powerful part of the stroke, or dead spot, the chainring reduces in size to speed you back into the power part of the stroke. This is different from an ovalized chainring that merely adds two teeth to maximize stroke in the power phase. An Osymetric 52-tooth chainring would be similar to a 55-tooth in the largest portion of the cam, then gradually reducing to a 49-tooth over the dead spot. To install the chainrings, you'll need to make adjustments to the derailleur height and width, with the included screw. And you'll also need to spend time fine tuning the rear derailleur. The first ride may seem a bit awkward, but after a few times out you'll feel more power in your stroke and be less aware of any inconsistencies in chainring shape. The Osymetric O-14 5-Arm Chainring fits any crankset with a 130mm BCD. It is available in 42t, 44t, 52t, 54t, and 56t.

PowerTap C1 Chainrings with Sensor PowerTap C1 Chainrings with Sensor
Trying to decide which type of power meter is right for you demands considerable time and energy. Once you figure out what you want and how much you're willing to pay, you have to delve into pages of proprietary terms and technology to figure out which products actually match that description. If you're looking for dual-sided power metrics and are running a five-bolt 110mm BCD crankset right now, consider the PowerTap C1 Chainrings with Sensor. They won't work with every crankset available, but offer a relatively wallet-friendly, dependable way to measure your watts if you have a compatible crankset already. For this price, getting precise, individual left- and right-side measurements is asking a lot. However, the C1 system does split your stroke in half to give its best calculation of each side's power, using built-in motion sensors to track cadence and power from within the unit. As you're coasting through a steep descent, don't worry about having to look down at your head unit and back-pedal; the system zeroes on its own as soon as you stop pedaling so that you can focus on the steep and winding road ahead. Compatible with Bluetooth SMART and ANT+, the C1 gets along with just about every major computer on the market too, so you won't have to swap to a different head unit to see data while you ride.

If you're looking to upgrade to a modular crankset without burning through your entire upgrade budget for the season, you can't do much better than Race Face's new Aeffect EXI Crank Arms. Occupying a notably more accessible price point than its pricier siblings, the Aeffect makes modularity available for your trail, XC, or enduro frame without requiring you to empty your wallet to afford it. Built dependably with a forged, 6066 aluminum construction, the Aeffect may not boast the same bombproof self-assuredness of its burlier siblings, but it still has a commendable strength-to-weight ratio for aggressive trail, XC and all-mountain/enduro riding. Just like its pricier siblings, the Aeffect boasts compatibility with a range of bottom bracket standards, but unlike them, it's delivered with a slimmer 24mm spindle. Swapping between chainring standards is quick and user-friendly with the design, which is compatible with 10 or 11-speed drivetrains, and most importantly, it affords you the option to run a direct-mount, one-by chainring or use a spider to mount double or triple chainrings if you prefer. Quiet and consistent, the Aeffect EXI shows, unsurprisingly, that Race Face has its tech and construction dialed on modular cranksets, and that a more affordable option doesn't have to mean a sacrifice on either account.

Race Face Atlas Cinch Crank Arms Race Face Atlas Cinch Crank Arms
We're not surprised that this was the year for Race Face to bring the steadfast Atlas line into the modular realm, and we're happy to see the time come. Stiffening the already burly model even further with a new forged construction, Race Face ensures the Atlas Cinch Crank Arms now provide DH, trail, and enduro riders with the option to run direct-mount single rings, double chainrings with a spider, or switch between the two. Though the Cinch isn't a new concept for Race Face--which previously released versions of it with the Next SL, SixC and Turbine cranksets--the Atlas fills the modular crankset void for the pedal mashing, crank-shattering DH set. And according to Race Face, it does so while boasting a 12% increase in stiffness compared to the Turbine. That increase in stiffness comes courtesy of the 3D forged back pocket design of the cranks, which laterally reinforces the crank arms while retaining their hardy silhouette. Much like what happened during your best friend's pivotal summer vacation between middle and high school, the Atlas crank arms came back slimmer as well as stronger this year, with Race Face shaving 33g overall (when the crank arms are paired with a 24t chainring) over the previous version by switching from machined arms to forged. The latest Cinch system also makes swapping the Atlas between your enduro monster and nimble trail bike quick and manageable. It's got a new axle that allows you to switch the crankset between bikes with different bottom bracket spacing without having to empty your wallet on an entirely new crankset. Even with its newfound versatility, we still feel the Atlas Crank Arms' continued, and even improved, durability is worth a mention. Without weighing your rig down, the Atlas' beefy design gives you the reassurance that you can make the day as big as you want it to be without the fear that you'll snap your crankset in half when you come back to Earth.

Once upon a time, having a crankset that was compatible with both direct-mount one-by rings and double or triple spiders would've sounded like far-off dream. However, Race Face's Cinch technology changed that in recent years, and this year, the company introduced the futuristic Atlas Cinch Crank Arms with 83mm Spindle, bringing its Cinch model to bikes with DH spacing for the first time. Mechanically abusive downhill riders can now take advantage of the added flexibility of modularity without having to sacrifice the pedal-mashing durability that made the workhorse Atlas crankset so popular among them before. In fact, with updates to its construction this year, the Atlas Cinch is now stiffer than ever, featuring a 3D-forged back pocket crank design for improved lateral stiffness and a new 7075 aluminum construction that's forged rather than machined, which affords it a claimed weight loss of 33g when paired with a 24T chainring. Despite these changes, the Atlas Cinch retains the rugged silhouette and impressive mud-shedding capabilities of its world-shrugging forebear. The Atlas Cinch's 83mm Spindle is designed specifically for use on DH rigs, while the regular model of the Atlas Cinch fills the modular void for hard-charging trail and enduro riders. Race Face's design allows you the option of directly mounting a one-by chainring or using a spider to attach a double or triple spread so you can set up your DH frame however you'd like but change your mind later if you need to. Race Face's aim is to maintain durability for a class of riders who expect to be able to blast through anything with no regard for whether their equipment can handle it or not. The company succeeded admirably, yet again, in creating something that will let you ride with the reassurance that it's as eager to barrel through apocalyptic terrain as you are.

Race Face Next SL Crank Arms - Fat Bike Race Face Next SL Crank Arms - Fat Bike
It seems paradoxical to pursue low-weight gear when you're riding a fat bike, but just because the tires and wheels are big and heavy doesn't mean everything else on the bike needs to weigh more. In fact, those jolly fat tires mean that the other components should try even harder to lose weight. The Next SL Cranks Arms for Fat Bikes, which Race Face claims constitute the lightest production carbon crankset in the industry, do just that. The Next SL Crank Arms omit a spider, so you can customize it to your tastes with a spider for multiple gears or a direct-bolt, one-by chain ring. This modularity speaks to the ever-changing standards of the industry, which routinely make top-end equipment obsolete after only a few seasons of use. Race Face makes aluminum spiders for all manner of setups, so the Next SL Crank Arms are currently compatible with anything from a direct mount one-by to a triple with the optional aluminum spider. This virtually limitless compatibility also all but guarantees them to be future proof. This is an investment that'll stay with you for years and years of use. The arms themselves are made from hollow carbon with no aluminum spine or filler material for the lowest weight possible. While the arms are pretty cool, the real star here is arguably the redesigned spindle. It's been beefed up from 24 to 30 millimeters, which lets Race Face use what it's calling a super aluminum that is 20% stronger than the usual 7050 alloy. That means less material for equal stiffness, which the increased diameter also helps with.

This year, that overachieving spirit has left us with the updated Race Face Next SL G4 Crank Arms, which manage to achieve the elusive industry-wide goal of being both lighter and stiffer than their predecessors through smart construction and an effective choice in materials. Race Face didn't leave itself much room for improvement when it introduced its top-of-the-line Next SL last year, so for the most part, the brand let the effective design of the Next SL stand relatively unchanged. It continues to trust the same hollow carbon arm construction, reshaping the slim arms only slightly to integrate with the redesigned Next Direct Mount chainrings. This process ended up shaving six claimed grams per arm from last year's weight. Anticipating the demands of one-by setups, Race Face also improved the system's lateral stiffness so it can better withstand the chain tension at acute angles that it's likely to experience regularly. It did this by using Super Alloy, a metal that boasts up to a 20% increase in strength compared to the venerable 7050 aluminum, in the spline interface. To offset the weight that this could've added to the setup, it then drilled out the end of the 30mm spindle, removing unnecessary material and saving four more claimed grams in the process. As with the Next SL, the G4 continues to use Race Face's innovative Cinch system, allowing you to switch between one-by direct-mount chainrings or use a removable spider to run a double or triple setup if you swap bikes or change your mind.

Race Face Next SL G4 Crankset Race Face Next SL G4 Crankset
Rather than deciding to leave its top-of-the-line Next SL alone for a few years, Race Face returned to the drawing board quickly for the design, setting ambitious, but unsurprising goals to eliminate weight and improve lateral stiffness on what's now known as the Next SL G4 Crankset. By trying to surpass a design few could find fault with, the G4 is definitely dreaming big, but with a few changes, Race Face managed to shave 20g off of the G4 compared to the Next SL. Race Face began by slightly reshaping the G4's crank arms, continuing to use its effective hollow carbon construction but tweaking the design in search of yet more weight loss. In doing this, it managed to shave 6g from each of the svelte arms without compromising any of their strength. Race Face was particularly concerned with the amount of tension that the chain would exert on the crankset due to the chain line angles of a one-by setup, so it upgraded the spline to an alloy that's a claimed 20% stronger than 7050 aluminum. To offset the weight that this could've added to the setup, it then CNC'd the end of the 30mm spindle, removing unnecessary material and saving four more grams in the process. We're attaching these crank arms to Race Face's Narrow Wide Cinch Direct Mount Chainring. Regardless of the size you choose, this ring's tenacious chain retention make it almost more valuable than the stiffness and low weight of the crank arms themselves. Almost. The direct-mount design is a lighter, stiffer interface than the old ring/spider/arm design, and it plays the role of babysitter by keeping the chain from jumping around like an unruly adolescent trying to avoid bed time.

Rotor 3D Plus Road Crankarms Rotor 3D Plus Road Crankarms
Carbon cranksets might be all the rage, but those of us looking for a certain aesthetic, or certain stiffness, are still inclined to look to well-made, machined aluminum cranks to complete our builds. The Rotor 3D Plus Road Crankarms are the pinnacle of alloy crank construction. They're Trinity drilled, like most Rotor cranks, which relieves excess material without compromising strength or stiffness in the process -like a much-safer drillium. The result is similar to a box-truss bridge, and is as stiff as you'd expect a Rotor crank to be. The 3D Plus Road also uses a 30mm spindle, but thanks to Rotor's work on the bottom bracket front, it'll fit everything from traditional, 28mm threaded bottom brackets to BB Right, to BB30, so no matter what kind of bike you're riding, you can ride Rotor cranks. Additionally, the 3D Plus are designed to accept any kind of rings, including Rotor's ovalized Q-Rings. You'll choose between 110mm and 130mm BCD, but if you change your mind down the road, the alloy spider can be swapped quite easily for the other size. This also makes it play quite nicely with spider-based powermeters, like the SRM or Quarq.

Rotor Flow Aero Cranks Rotor Flow Aero Cranks
Rotor's 3D Plus Road crank is a revolutionary design in the world of carbon versus aluminum components. Using Rotor's Trinity Drilling System and 7055 alloy, it is stiffer than most carbon cranks, and it is also compatible with virtually any bottom bracket system. The Rotor Flow Aero Cranks, based on the 3D Plus, therefore is a paradigm-changing crank designed for both road and pure TT bikes. The Flow Aero features the same proprietary Trinity Drilling System (TDS) as Rotor's 3D cranks. This process drills three full-depth holes from axle to pedal, which leaves behind a structure similar in form to box-bridges. This is unlike a classic hollow tube crank design, due to two additional interior "walls" left over after drilling. This gives the crank arms an exceptional strength-to-weight ratio. Unlike the 3D cranks, the Flow features a smooth exterior and a shape that widens slightly as you move from the spindle to pedal. A crank does not fully intersect with laminar airflow while riding. This is due to the fact that the front wheel and fork have already cut through the air and the turbulent air that meets the cranks has less resistance than unbroken air. Because of this, the smooth surface of the crank excels to be even more aerodynamic. It gives a six second time reduction over a 40k TT at 200 watts, and in a race that is often won by seconds, this advantage could mean a place on the podium. Its design is worthy of both pure time trial frames, as well as your lightweight road frame. Please note that the chainrings are not included with this crankset. The QX rings are recommended, though you may use Rotor's round rings if your preference is toward classic shape. The Rotor Flow Aero Cranks are available in sizes 110-170mm, 110-172. 5mm, 110-175mm, 130-170mm, 130-172. 5mm, and 130-175mm. They come in the color Black.

Rotor QX2 Inner Chainring Rotor QX2 Inner Chainring
At Interbike this past fall, Rotor finally released its much-anticipated mountain bike cranksets and compatible ovalized chainrings. Rotor took its road-winning technology and parlayed that success into rings that work on the rough trails and surfaces that usually cause stutters in the efficiency of your power output. The QX2 is designed as the inner chainring for a standard 2-ring mountain bike drivetrain. Ovalized chainrings are essentially designed to maximize the efficiency of your pedal stroke by prolonging the power zone and minimizing dead spots. They are machined with a subtle oval shape and, with multiple mounting holes, can be "clocked" to maximize the effects for your biomechanics, pedaling style, and bike geometry. The QX2 features an ovality of 10%, which helps you accelerate better and experience smoother torque and better grip off road. Additionally, the alternating thick and thin tooth profile keeps your chain from dropping -- even in the roughest conditions. This eliminates the need for a chain guide. The Rotor QX2 Inner Chainring comes in sizes: 60-22t, 60-25t, 60-26t, 60-27t, 64-25t, 64-27t, 74-25t, 74-27t, 80-26t, and 80-27t. The ring comes in the color Black.

Rotor REX 1.1 Cranks Rotor REX 1.1 Cranks
Rotor has devoted itself to a new line of mountain bike cranks it's calling "REX," and they are based on the same successful Trinity Drilling System as all Rotor cranks. The REX 1. 1 is for a 1x drivetrain. The Trinity Drilling System (TDS) is a method of hollowing out the cranks, which reduces weight and maximizes stiffness. Unlike traditional hollow crankset design, the Trinity Drilling System drills three channels from the pedal to the spindle. While these holes remove excess material, they also leave behind two thin walls, making them stiffer than the design of a single hollow chamber. The TDS creates a maximum strength-to-weight ratio, and the arms were constructed using a new 7055 alloy, which is both lighter and more durable than the more often used 7075. UBB30 & UBB24 axles ensure maximum frame compatibility. Without the bottom bracket they weigh in at 489grams. The Q-factor is 163. The Rotor REX 1. 1 Cranks are available in sizes 170mm, 172mm, and 175mm. Please note the REX 1. 1 does not include a chainring.

If you, like a few of us old souls around the Competitive offices, are holding fast to your belief in the soul of mechanical shifting, Shimano hasn't abandoned you. Though the world may very well be moving towards 100% electronic drivetrains someday in the future, mechanical still makes a hell of a case for itself. With smooth lines, elegant finishing, and functionality beyond reproach, the redesigned mechanical Dura-Ace drivetrain calmly holds its own in this brave new world of wires, batteries, and display screens.

Call upon your granny gear when needed with this lighter, stronger version of a top-end classic, and embrace tried-and-true tradition of cables. Of course, in the even that you do decide to run electro-shifting, the crank's ring profile plays just as nicely with Di2 derailleurs. Shimano didn't introduce any drastic changes to its proven four-arm design, but it did make a few subtle, deliberate changes to bring it up to the most modern compatibility standards. By widening the crank arm, Shimano was able to move the chainline 0. 5mm outboard; this barely perceptible repositioning was just enough to give the crankset broader compatibility with shorter chainstays and the growing number of road bikes built for disc brakes. The gram counters will be happy to learn that beefing up the crank arm didn't result in a change in weight. Instead, Shimano was able to carefully remove internal material where it wasn't needed, strengthening only the most crucial areas of the crank arms and actually reducing weight by around a claimed 7g over the previous generation. The Japanese brand calls this process Hollowtech II, but it could very well be sorcery for all we know. In addition, Shimano also slightly reshaped the chainrings' gear teeth profile to adapt it to the gearing on disc brake-equipped race bikes. As alway...

Sleeker graphics, improved functionality, and a whole host of trickle-down technology from XT and XTR have closed the gap between SLX and Shimano's pricier groupsets, and we're thrilled about it. When you spec your bump-devouring trail frame with the SLX FC-M7000 1x Crankarms, you'll gain access to Shimano's impressive Hollowtech II construction, more consistent chain retention, and a lighter design than previous versions of SLX.

As we mentioned, the biggest change that came to SLX crank arms this year is their transition to a Hollowtech II construction. Shimano manages to create stronger crank arms than most solid versions with this design, which is constructed with forged aluminum arranged around a hollow center. This strategic use of material shaves weight while still equipping the crankarms to be bashed over successive hits without complaint, and to transfer power as you work hard to turn them over. It's a fitting construction for today's breed of incredibly capable trail and enduro frames. They pair with either a 30T, 32T, or 34T SLX chainring, which have all been upgraded to offer better chain retention, significantly narrowing the gap between XT and SLX.

Shimano has been steadily upgrading its road drivetrain hierarchy for the past several years now, benevolently delivering trickle-down technology to its more wallet-friendly groupsets to keep improving its designs across price points. Fortunately, the brand hasn't neglected the practice on the mountain side of things either, and this year treated its workhorse SLX groupset to a full 11-speed upgrade. Now built with sleek XT aesthetics and the durability we've always associated with Shimano, SLX looks to recapture some of the pre-spec'd bike build market with its up-to-date technology and accessible mid-range price point. Aiming to appeal to a range of riders and preferences, Shimano made SLX available in several different configurations, with the FC-M7000 2x Boost Crankset created for riders who prefer the gear range of a double chainring and the increase in stiffness of Boost spacing. It benefits from Shimano's Hollowtech II aluminum construction, which consists of a careful cold-forging process that results in stiffer, lighter crank arms than their solid counterparts would be. Rather than making one standard design for each configuration, Shimano adapted its construction details to each configuration, giving the FC-M7000 close gear ratio combinations so that you experience as little lag time in between shifts as possible -- especially helpful when you have seconds to drop into a low gear before a steep roller or are trying to accelerate quickly heading into a flat stretch. The chainrings themselves now boast teeth built with Shimano's Dynamic Chain Engagement technology, which suit them to manage different power outputs depending on the ring. This improves shifting overall by delivering more tailored shifts, along with an always-welcome increase in stiffness and improved chain retention.

Shimano did right by its second-from-the-top groupset, and using its Hollowglide technology and aluminum's storied durability, the brand crafted the Outer Chainring with its signature mix of reliability and longevity. A hollow construction shaves valuable grams without sacrificing stiffness, while offering more efficient power transfer and more precise, responsive shifts. Though Shimano doesn't reveal the exact measurements of its top-secret BCD, we do know that its chainrings are universally compatible throughout its 11-speed drivetrains. So, even if you're waiting to have full Ultegra bestowed on you by sponsors, you can still run an Ultegra chainring on your 105 11-speed crankset, though not if you're still riding on 10-speed.

Shimano Ultegra 6800 Crankset Shimano Ultegra 6800 Crankset
We've all got multiple cycling lives, ranging from racing road and 'cross to riding charity sportives and all the long training miles that go into preparing for them. Few cranks can comfortably straddle every aspect of the mutable cyclist's life like Shimano's Ultegra 6800 Crankset, which brings the stiff Hollowtech II design of Dura-Ace to a price that appeals to riders outside of the peloton. The Ultegra 6800 Crankset may not be as light as the Dura-Ace model, but it still checks-in at a race-worthy 765g. While the Ultegra 6800 drivetrain's two extra speeds may be the most noticeable upgrade, in truth, the entire crankset has been redesigned to follow in its big brother's footsteps. The biggest change is the use of a four-arm, rather than the traditional five-arm, spider, which saves a claimed 26g. The new crankset design also standardizes the bolt circle diameter, so it accommodates standard or compact chainrings without having to spring for a completely new crankset. You're able to switch gearing from a 55-42t down to a 46-36t in a matter of a few minutes.

Shimano XT FC-M8000 1x Crank Arms Shimano XT FC-M8000 1x Crank Arms
Building up a new bump-devouring enduro sled has never been more fun. Rather than agonizing over the cost of pro-level drivetrains, self-sponsored cyclists have the privilege of riding components nicer than what the pros of not so long ago were riding. Shimano's XT drivetrain is a perfect example of this; if XTR's not in the cards, save yourself a giant credit card bill and upgrade to XT instead. The new XT FC-M8000 1x Crank Arms recently received an opulent upgrade, returning with better bearings and seals as well as XTR's Hollowtech II Construction, ready to barrel through the rough and rocky stuff with poise. Before you pick up the FC-M8000 and start to doubt that it's solid enough to actually withstand the abuse you're about to give it on-trail, think about Hollowtech II. Cold-forged aluminum with a hollowed center establishes an extremely durable structure, while shaving unnecessary weight from the middle of the crank arms. Don't concern yourself with longevity or durability worries, because the FC-M8000's bombproof construction actually makes it stronger than many solid crank arms. Enjoy smoother bearings and seals better equipped to keep out dirt and debris, and rest assured that Shimano's simple thru-axle and pinch bolt design returns to make installation quick and pain-free, once again.

The new Shimano 11-speed XTR group borrows a heap of technology from its older sibling, Shimano's top-end XTR line, resulting in a component group that closely mirrors its more expensive kin and offers a more wallet-friendly option for riders on a budget. It now steps up to the new Boost 148 standard with the XT FC-M8000-B2 Boost Double Crankset, which keeps the gears turning with advanced Hollowtech II construction, updated bearings, and a Boost-compatible width. While Shimano's bearings have always been solid, the M8000 gets an update with smaller bearings and improved seals for an even smoother ride that efficiently transfers power into forward motion. The Hollowtech II cold-forging process results in crank arms that are both stiffer and lighter than most solid crank arms. They've also been reshaped with an asymmetric design that's different than, yet evokes the sophistication of, XTR. The right arm is pressed together with the hollow 24mm spindle at the factory, and the splined left crank arm is secured with perhaps Shimano's best detail: two pinch bolts to secure the arm once the bearing preload is dialed. In our experience, it's a superior design in terms of installation, trail manners, and durability. The bottom bracket is improved as well, with a lower weight, higher durability, and reduced seal drag. The Shimano XT FC-M8000-B2 Boost Double Crankset is available with a set of 36t and 26t chainrings and several crank arm lengths to suit individual rider needs.

Answering the demand for one-by mountain drivetrains, Shimano has engineered the XTR FC-M9000-1 one-by Race Crank Arms, as part of the new XTR 9000 groupset, to be a light and reliable crank for those who prefer simplicity. The XTR M9000 crank arms are designed with the same hollow-armed alloy technology that Shimano uses on its double chainring drivetrains. The slight difference is that that left arm is now hollow-bonded to further reduce weight, without compromising durability and stiffness. Without the bottom bracket, the cranks weigh 583 grams. Meanwhile, the right crank arm now sports a four-arm spider that, regardless of the one-by designation, is compatible with all XTR 9000-series single and double chainring setups. It should be noted that the narrower Q-factor, 158mm, while increasing pedaling efficiency, will not work with several full-suspension frame designs.

Shimano's latest XTR crankset is, undoubtedly, its best mountain crankset ever. The crankarms themselves have received a few upgrades, mainly to reduce weight, but the chainrings have been extensively. The result is that the XTR FC-M9000-2 2x Race Crankset is lighter and stiffer than any XTR crankset before. The M9000's crankarms use Shimano's tried-and-true formula--hollow-armed aluminum arms with proprietary spider and ring technology. A few changes have been made, however. The left side (non-drive) is now hollow-bonded for a reduction in weight. The drive side also loses a few grams, while it carries a new four-bolt spider that is compatible all of the single- or doublering configurations os Shimano's new 9000 group. The chainrings have been completely redesigned for reduced weight and increased stiffness. The rings are hollow. They are stiffer than ever, however, thanks to their carbon-reinforced titanium alloy construction. Shift paths have been computer optimized for smooth and virtually instant shifting. The teeth are also titanium and have been hollowed out as well to save every possible gram.

So, Shimano's made their XTR arms available for those of us who wish to use a single ring but can't resist the glossy gray allure of Japanese drivetrain parts. The Trail version of these arms, which you see here, is constructed using Shimano's tried-and-true HollowTech II technology, though the Trail version is a little less hollow than the Race versions.

With the launch of its CX1 groupset last season, SRAM ushered this popular setup into the mainstream by eliminating all the hurdles to achieving a perfect single-ring drivetrain. This year, SRAM expands the one-by line with its new Force 1 system, boasting phenomenal cyclocross functionality that crosses over just as well to road and gravel bikes. The Force 1 BB30 Crankset sits at the center of the group, driving forward with a clean chain line and exceptional chain retention.

At the center, a forged alloy spider provides a durable-yet-lightweight anchor while the SRAM X-SYNC chainring brings some extra chain retention features to the table to make this crankset really hum. X-Sync chainrings feature a distinctly tall and squared-off tooth shape that catches the chain earlier in the pedal rotation than standard, triangular teeth for improved chain stability and retention. The teeth's narrow, sharp profiles and rounded chamfer edges also help with chain retention, especially in minimizing chain deflection. SRAM also keeps the oft-muddy conditions of 'cross in mind: recesses help clear mud to move the chain swiftly through its rotation for smooth power transfer that reduces catches and mud suck.

SRAM Force 22 GXP Crankset SRAM Force 22 GXP Crankset
Beyond the 22 gears, the Force 22 GXP Crankset draws heavily from SRAM's Red technology for more precision and power than before. SRAM lays up the cranks with unidirectional carbon fibers. When placed parallel to each other, the strength of carbon fiber is maximized so that the loads work along the axis of the fibers. This also means the amount of carbon used is able to be reduced, which in turn means greater weight savings. The unidirectional carbon decreases flex, which means every pedal stroke counts for a bit more. The spider it's mated to is a forged alloy that includes the spindle on the non-drive side. SRAM chose to use a 130mm diameter spider, which means you're able to use it with most aftermarket chainrings. Taking the standard a bit further, however, the mounting bolt has been incorporated into the backside of the crank arm. This reduces deflection and ensures no skipped front shifts. Trickling down from the SRAM Red group are the Exogram chainrings. SRAM uses its "True 22" X Glide R chainring calibration, ensuring no missed shifts. They are machined from 5mm 7075-T6 aluminum and specifically designed for the 11-speed system with optimized shift ramp profiles and stiffness.

2x and 1x drivetrains have become the norm, rather than the exception, within the last few years. The SRAM GX gruppo provides several options for each layout. The GX1 1400 GXP Crankset with Boost 148 technology is SRAM's most modern aluminum 1x crankset. You'll need to use these cranks with the Boost 148 drivetrain, however, for compatibility. The SRAM GX1 GXP Crankset works with a single up front and will only mount to a Truvativ GXP bottom bracket. The GX crankset comes in several versions, including the value-oriented 1000 and the mid-range 1200, but the 1400 is the best there is. It's lighter than the others, thanks to hollow-forged crank arms, but it doesn't lose any stiffness to its solid-armed sisters. Mated to a forged aluminum spider, in fact, the GX is stiffer than most cranks on the market, even far more expensive competitors. The SRAM GX 1x chainring uses X-SYNC technology. Each tooth's thickness is CNC machined to work seamlessly with the chain's inner and outer links to hold the chain in place in any terrain. With X-SYNC you never need a front derailleur, tensioner, or chain keeper to maintain perfect control over your chain. This particular version of the GX crankset is Boost 148 compatible. Put simply, Boost 148 is a wider rear hub. It provides several advantages over the standard rear hub, including increased wheel stiffness and durability, tighter handling, improved frame geometry with shorter chainstays, wider and stiffer suspension pivots, a wider range of chainring options, and greater clearance for today's modern tires. The boost 148 option for the SRAM GX crank increases the spacing at the bottom bracket for a more direct chainline when using a wider rear hub.

SRAM NX 1x BB30 Crankset SRAM NX 1x BB30 Crankset
Whether you're building up your first mountain bike or looking to replace an old, worn-out crankset, the SRAM NX 1x BB30 Crankset features trickle-down technology from SRAM's top-tier offerings at an affordable price that will leave some cash in the bank for rent and a few entry fees. The crank arms are fashioned from light, stiff, and durable aluminum for confident and efficient power transfer from the pedals. At the center, a forged alloy spider provides a durable yet lightweight platform to power forward while the SRAM X-SYNC chainring brings some extra chain-retention features to the table and make this crankset really hum. X-Sync involves a distinctly tall and squared-off tooth shape that catches the chain earlier in the pedal rotation than standard triangular teeth for improved chain stability and retention. A narrow, sharp profile with rounded chamfer edges also helps with chain retention, especially in minimizing chain deflection and just generally helps keep the chain on track. SRAM also kept unexpectedly muddy conditions in mind, and includes recesses that help clear mud to move the chain swiftly through its rotation for smooth power transfer without any distracting catches or mud sucks. The SRAM NX 1x BB30 Crankset is compatible with BB30 equipped framesets.

You get it: one-by is the future of mountain biking, it's the only way to upgrade, it's the Next Best Thing for good reason, etc. You believe wholeheartedly in the hype--and rightfully so--but you can't drop a full month's rent on bike parts again or your roommate may do something drastic. Fortunately for you and your domestic situation, SRAM's NX 1x GXP Crankset makes one-by drivetrains more accessible for those not blessed with unlimited upgrade budgets. The introduction of the NX groupset has inspired a level of buzz usually reserved for technologies triple its price. It was created to be an entry-level, budget-friendly option, and its simple, solid construction won't necessarily be winning industry-wide awards for weight, but is already attracting serious attention as the most affordable one-by crankset on the market. In an age of carbon-fiber arms races, combing new technologies with economy is an innovation in and of itself. SRAM offers the NX in a variety of sizes and lengths, but the 170mm and 175mm GXP options are designed to be ideal for your XC, trail, or all-mountain rig, with a solid 6000-series aluminum construction and a GXP spindle. The SRAM X-SYNC chainring itself also boasts a durable aluminum construction, with each tooth machined to interact seamlessly with the chain's inner and outer links for smooth, powerful pedaling whether dicing down a steep backside hill or laboring along a winding climb.

SRAM Red BB30 Crankset SRAM Red BB30 Crankset
The engineers at SRAM improved upon the first-generation Red crankset by going bigger, and ultimately offering a lighter, stiffer, and more precise crankset. Built with Exogram technology, the new SRAM Red BB30 Crankset uses a larger carbon-optimizing structure, which enables them to use less material without sacrificing stiffness. The crankset features a considerably burlier arm shape than previous versions with a true hollow cross section. The design also allows SRAM to rotate the spider in order to utilize the large, sturdy crank arm as a bolt anchor and reduce the number of spider arms to four, giving the cranks a sleek, air-splitting profile. The rotated spider also reduces deflection from shifting, which minimizes the previous generation's occasional tendency to hamper the precision and crispness of front shifts. To ensure compatibility with aftermarket chainrings, SRAM still uses a 130mm bolt circle diameter on the standard cranksets and 110mm bolt circle diameter on the compact cranksets. SRAM's stiff X-GlideR chainrings are machined from 5mm thick 7075-T6 aluminum and have been carefully modified to work with the 11-speed drivetrain. The chainrings feature enhanced shift pins and shifted ramp profiles to work seamlessly with the Yaw-caged front derailleur.

SRAM Red GXP Crankset SRAM Red GXP Crankset
SRAM's Red groupset has solidified a spot among the frontrunners of the peloton with its precise, reliable, "True 22" shifting. The Red 22 GXP Crankset sits at the center of the group, guiding the chain with SRAM's innovative Exogram technology for exacting power transfer and clean gear shifts. While the original SRAM Red crankset used a carbon-wrapped foam core to mold the cranks, the current design incorporates a true hollow cross-section. By laying-up the carbon to create a higher volume spider and larger diameter crank arms, SRAM is able to use less material while maintaining the power-transferring stiffness we expect from a carbon crank. The spider was also rotated to take advantage of the new shape, situating the fifth mounting bolt on the back of the crank arm itself to reduce deflection during shifting and extra-mashy efforts. While the spider arms have been reduced to four, SRAM still uses a 130mm bolt circle diameter on the standard cranksets and 110mm on the compact cranksets for compatibility with aftermarket chainrings. The included SRAM Exogram chainrings are machined from 5mm thick 7075-T6 aluminum and feature SRAM's X Glide R design to complement the movement of the yaw-caged Red front derailleur. SRAM used extensive computer-aided finite element analysis to optimize stiffness, shift pin locations, and ramp profiles for smooth shifting that still allows the removal of any excess material to save weight. This particular Red 22 GXP Crankset is compatible with the SRAM/Truvativ GXP bottom bracket standard, including the low-friction hybrid ceramic bearing option.

SRAM Red Road Chainring SRAM Red Road Chainring
With its introduction of the Red group, SRAM again proves that it's always on the leading edge of component design and technology. The SRAM Red Road Chainring is an integral part of the Red group and serves as a platform for precise shifting across SRAM's 22-speed gear range. It's also got a sleek aesthetic that builds on the SRAM Red 10-speed chainring design. The colorway title, "falcon grey," calls to mind the swift and precise dive of a peregrine, which is appropriate since the SRAM Red Chainring's improved shift timing pins and ramps increase shifting speed and precision when integrated with the Yaw-caged SRAM Red front derailleur and chain. SRAM engineers borrowed design components from the X-Glide drivetrain technology found in their top-end XX mountain group to create a road version, X-GlideR. The new SRAM Red Chainring is also stiffer, thanks to precise machining of the 5mm 7075-T6 aluminum, which improves power transfer and facilitates faster, quieter, and more precise shifting than comparable chainrings. It's available in several size options, allowing you to maximize your cycling experience based on your specific gearing needs.

Sloppy shifting is the bane of serious climbers. You know the feeling--you shift, nothing happens, and then BANG! You slam down two gears and totally lost momentum. SRAM's Red-X Glide Chainring is ridiculously responsive, though, so you'll never have to wait for your chain to drop down or jump a ring when you really need it to. By redesigning the chainring to better align with the chain's pins and increasing the number of points where shifts can engage, SRAM was able to speed up shifting to light-speed levels, so there's never a delay between moving the lever and switching up your gearing. SRAM manufactured the Red X-Glide from CNC-machined 7075-T6 aluminum for serious stiffness, and designed it with a multitude of BCDs, teeth options, and colors, so you can find the perfect one.

SRAM Rival 1 GXP Crankset SRAM Rival 1 GXP Crankset
With one-by drivetrains firmly established as a viable option in the mountain and cyclocross realms, SRAM is now in the process of expanding the one-by paradigm to the road with its Rival 1 group. The Rival 1 GXP Crankset sits at the center of the group to guide the chain through the pedal stroke with perfect lines and outstanding chain retention. While some of us at Competitive's office remain skeptical of a sole chainring's utility in more mountainous regions, others are eager to sacrifice a top-end gear or two for the weight savings and clean simplicity of the new options. Whatever the case, this setup certainly shows promise for riders living in less aggressive topographies and may be an ideal setup to ditch the front derailleur and save some weight for crits and time trials. The crank arms are fashioned from forged aluminum for efficient power transfer at a much lower price point than their carbon fiber counterparts. The chainring's teeth feature a distinctly tall, squared-off profile that catches the chain earlier and releases it later in the pedal rotation than standard triangular teeth, improving chain stability and retention. The teeth also have rounded chamfer edges to aid chain retention and minimize deflection. SRAM also keeps b-road adventures in mind by including recesses that help clear mud.

Building on the original X-Sync's renowned chain retention ability, the X-Sync 12-Speed Direct Mount Chainring changes things up with claims of even better chain control. As with the original design, each tooth is CNC-machined to support the chain's inner- and outer-link widths by providing a variable thickness from tooth-to-tooth, so the chain and chainring essentially lock together as you pedal and push away mud with ease. The departure in design lies in the tooth shape. Where the original X-Sync teeth took on a boxy shape, X-Sync 2 is narrower to accommodate the 12-speed Eagle chain and features teeth that more closely resemble those of a shark. Boasting aggressive profiling, these teeth hold the chain securely in place like a megaton aquatic predator latching onto a precisely thrown oxygen tank, then let it to glide seamlessly back to the cassette for smooth, friction-free turns.

It's no secret that SRAM's revolutionary 1x11 drivetrain platform has risen to dominance in the world of mountain bikes. While it originally debuted at the top-end of the market, SRAM has thankfully trickled down 1x11 technology into more wallet-friendly groups, notably the X1 groupset. The SRAM X1 1000 BB30 crank you see here goes to show that the company is as dedicated to the everyday rider and weekend warrior as it is to the pros. The X1 crankset comes in several versions, including the top-notch 1400 and the midrange 1200, but the 1000 is where you get the best bang for your buck. It doesn't get the hollow-forged arms of the 1400, and it uses a slightly heavier 6000-series aluminum for its arm material than the 7000-series used in the 1200, but all told, the 1000 crank gives up only 50 grams of weight compared to the lightest 1400. Mated to a forged aluminum spider, in fact, the X1 1000 is stiffer than most cranks on the market, even far more expensive competitors. Like the XX1 and X01 cranksets, the X1's X-SYNC chainrings -- available in size from 30 to 38 teeth -- feature a special alternating-offset tooth profile that "locks" the chain onto the ring to prevent dropping, even over the most abusive and bumpy terrain. The SRAM X1 1000 BB30 Crankset is available in two arm lengths -- 170mm and 175mm -- and in the color Black. It is for use with BB30 or PF30 bottom bracket platforms only, not standard threaded bottom brackets, and it comes with a 32-tooth chainring.

SRAM XX1 Eagle 12-Speed BB30 Direct Mount Crankset - Boost SRAM XX1 Eagle 12-Speed BB30 Direct Mount Crankset - Boost
One-by drivetrains have seen a surge in popularity as of late, and SRAM continues to lead the way towards simplified shifting and single derailleur drivetrains with its all-new, 12-speed XX1 Eagle group. Not to ignore other industry trends, the SRAM XX1 Eagle 12-Speed BB30 Direct Mount Boost Crankset bumps the chainline out three millimeters to pair with your shiny new Boost-equipped frameset for race-worthy power transfer, impeccable chain retention, and a flash of golden flair. Building on the original X-Sync chainring's renowned chain retention ability, Eagle's X-Sync 2 chainring changes things up with claims of even better chain control. As with the original, each tooth is CNC-machined to support the chain's inner- and outer-link widths by providing a variable thickness from tooth-to-tooth, so the chain and chainring essentially lock together and push away mud with ease. Where the original X-Sync teeth took on a boxy shape, Eagle's chainring boasts aggressively profiled teeth that hold the chain like a wild-eyed kitten clinging to a catnip-soaked mouse toy before letting it glide seamlessly back to the cassette for smooth, friction-free spinning. SRAM utilizes its Carbon Tuned technology to fashion the XX1 Eagle arms with a proprietary, hollow carbon layup that increases stiffness where it's needed and minimizes excess material for an overall reduction in weight. The direct-mount chainring interface also affords the option of quickly subbing different sized rings for different shapes of terrain, giving the true all-mountain racer the start-line flexibility to adapt to a given course.

SRAM XX1 GXP Direct Mount Crankset - 156 Q-factor SRAM XX1 GXP Direct Mount Crankset - 156 Q-factor
SRAM's XX1 GXP Direct Mount Crankset achieves a low 156 Q-factor by taking advantage of two of the crank's essential design characteristics: spider-free mounting and a single chainring. The result places the pedals over a centimeter closer to the bottom bracket than they'd be on a 168. Though that may not seem like much in the vacuum of a tech spec sheet, that centimeter can feel like miles when the extra clearance provides a bit more room for error on the ragged edge. Except for the narrower profile, this crankset features the same lightweight, carbon stiffness of the wider model. The standard XX1 chainring-to-chain redesign returns unchanged, featuring a pattern of wide/narrow teeth with tall, square edges to maintain early, confident engagement for popping up rocky climbs or dropping the hammer in a finale. The direct mount version also affords the option of quickly subbing different sizes of rings for different shapes of terrain, giving the true all-mountain racer a bit of start-line flexibility to adapt to a given course, and SRAM's GXP design uses a 22mm gutter on the non-drive side to reduce friction and weight without sacrificing the drive side's power transfer.

SRM SRM Powermeter Rotor 3D+ SRM SRM Powermeter Rotor 3D+
Rotor cranks are among our favorites, both for their brutally industrial design, as well as their incredible stiffness and shifting performance. SRM is also among our favorites, as the accuracy of its power meters is tough to beat, and the integration of the power meter into various cranksets is top notch. No surprise, then, that we're offering this combo. It's simply the top dog in an increasingly-crowded field. The SRM measures power output using strain gauges, and then transmits that data wirelessly to any ANT+-enabled head unit. It's functional at essentially all cadences and power outputs, and delivers results with +/- 2% accuracy. The Rotor crank arms pick up where drillium left off, but it's executed in a refined, functional manner with none of the structural questions left by drillium. This is to say that every unnecessary gram has been precisely CNC-machined away, and what you're left with is what you need, and not a bit more. The 839-gram combined weight for power meter, chainrings, and crankset is shockingly low, and gets us thinking what else we'll need to add to get our bikes to UCI minimum, as the power meter was always kind of a handy boat anchor.

TruVativ Descendant 11-Speed BB30 Direct Mount Crankset TruVativ Descendant 11-Speed BB30 Direct Mount Crankset
Celebrating the start of the new season with a brand new crankset only to need another around the solstice isn't our idea of efficiency. Unless you're a pro crushing the DH race circuit, you should be riding on componentry that gives you the freedom to take risks and do something stupid every once in a while without falling apart. Enter Truvativ's well-respected Descendant line. For 2017, parent company SRAM called for an upgrade, and the resulting Descendant 11-Speed BB30 Direct Mount Crankset delivers new, streamlined aesthetics as well as SRAM's inventive new X-SYNC chainring profile.In starting with solid 7000-series aluminum, Truvativ gave the Descendant the enviable blend of lightness and bump-crushing rigidity that trail and all-mountain/enduro riders need as distinctions between categories continue to grow blurrier. While saving weight with aluminum, Truvativ also added a direct mount ring, slimming down the overall design and cutting grams compared to bulkier bolted designs. Anticipating riders wanting to add extra protection to vulnerable chainrings, Truvativ made the Descendant compatible with bash guards, which is good, because you'll want to protect the X-SYNC chainring's impressive profile for as long as possible. SRAM's efficient new chainring hasn't earned its extensive praise for nothing: squared-off teeth cling to your chain and refuse to let in everything from bouncy root lattices to thick patches of mud.

Tracing its history back to being the unbranded crankset behind a multitude of podiums earned by the members of SRAM's pro team, Descendant cranksets have enjoyed an illustrious history. Now known by name by the public for its workhorse capabilities and budget-friendly price, the Descendant 11-Speed BB30 Direct Mount Boost Crankset was treated to an update for 2017. If you're looking for a versatile, bombproof crankset that won't blow your travel budget for the summer, you won't find much with a better fit than the Descendant. A 7000-series aluminum construction is responsible for much of the Descendant's behavior, allowing it to occupy a reasonable price point and equipping it with the combination of stiffness and lightness that adapts it so well to all-around trail and all-mountain riding. While you're launching off a drop bigger than you expected or dicing through a rocky, hand-numbing line, you can ride with assurance that the Descendant won't fall apart. The direct mount ring also simplifies the design, allowing the streamlined new aesthetics to stand out and trimming bulk over bolted models. For added peace of mind, the Descendant accommodates a bash guard to add protection for the chainring, and includes SRAM's impressive X-SYNC chainring for precise chain retention, its squared-off teeth holding onto chains admirably through muddy, wet conditions and dry days alike.

Truvativ's Descendant line has enjoyed a long history as a workhorse group of components, tested on the rigors of the pro circuit before being released to the masses. For 2016, parent-company SRAM sought to freshen up the somewhat outdated aesthetics of the cranksets, and the resulting Truvativ Descendant 11-Speed GXP Direct Mount Crankset represents a clean, well-executed makeover that firmly announces Descendant's march towards the future. Stiffness and durability earned the highest priority as SRAM redesigned the Descendent Crankset, but ease of use and overall practicality were clearly considered as well. In adopting a direct mount ring, SRAM shaved weight from prior models, and it bestowed a single updated X-SYNC chainring upon it, complete with its commendable tooth profile to engage your chain early and help it function eagerly in muddy, sticky conditions. Made with forged 7000-series aluminum, the Descendant's construction blends lightness and durability with uncompromising rigidity to handle big hits and hard landings without showing distress. Plus, for those of you have a habit of bashing your chainring on rocks more times than you can count during a ride, the Descendant gives you the option to add a bash guard for extra reassurance, and it also works with any of SRAM's 1x drivetrains.

Truvativ's Descendant line of cranksets have been quietly tucked away on the flashy builds of SRAM's pro riders for years now, and they've earned themselves a pretty devoted following amongst the public more recently for their rugged construction and palatable price tag. To bring the Descendant line into 2017 this year, parent company SRAM made a few choice upgrades to aesthetics and gave the Descendant 11-Speed GXP Direct Mount Crankset Boost the gift of its chain-grabbing X-SYNC chainrings; in our opinion, making a good thing even better. SRAM constructs the Descendent crankset with 7000-series aluminum for its ability to remain light and impressively stiff when called upon, keeping the walls solid throughout the entire design rather than compromising structural integrity to save weight with a hollow construction. The Descendant has earned praise already for its low weight despite this decision, and on this version, the direct mount ring eliminates more bulk, letting the clean updated aesthetics of the crank be showcased uninterrupted. As you confidently crush trails that used to leave you clinging white-knuckled to the bars, the Descendant's X-SYNC 32t chainring will be latched onto your chain, its commendable squared-off teeth expertly guiding it around and around whether the day features dusty singletrack or mud of unknown depths.
