Pioneer Dura-Ace R9100 Powermeter Crankset Pioneer Dura-Ace R9100 Powermeter Crankset
Proven in the peloton and available with Shimano's flagship new flagship drivetrain, the Pioneer Dura-Ace R9100 Powermeter Crankset adds data collection to your training, helps you analyze every ride, and doesn't compromise the drivetrain for those of us who appreciate a build where every component is the same make and model. Its sleek design integrates cleanly into the crankset and features dual-leg strain gauges for independent pedal data and other detailed metrics. It transmits those data to any ANT+ cycling computer, and pairing it with one of Pioneer's own cycling computers opens up an even wider world of torque vector analysis for those of us who want to dig into the really nitty gritty minutiae in search of marginal gains and a few extra watts. The system measures pedaling force, direction, and overall efficiency via dual strain gauges bonded to the crank arms. Either sensor unit captures 12 points of rotation at 30-degree intervals by measuring minute changes in the shape of the crank caused when force is applied while pedaling. From this, force is calculated in both the direction of rotation and the radial direction. The combination of these two force components indicates the direction in which the total force is being applied, which is shown using the system's force vectors. Also, a magnet ring that attaches to the bottom bracket measures the position of the crank, allowing precise display of the force vectors at every 30-degree interval throughout rotation. The force vectors for one full rotation are then wirelessly transmitted to any ANT+ head unit via the transmitter module bolted in the crankset's spider. The information centers around pedaling efficiency, giving riders the ability to target inefficiencies for improvement in training and racing. When pedaling efficiency is high, most of the rider's power is being used to rotate the pedals. So, the force measured in the direction of rotation at each of the 12 points is combined to give the total po...

Pioneer Left Arm Power Meter Installation Kit for Consumer Supplied Cranks Pioneer Left Arm Power Meter Installation Kit for Consumer Supplied Cranks
While dual-leg power measurement is arguably the end goal for obtaining the best data and range of metrics possible, it also comes with a price tag that isn't for the faint of heart. Pioneer gives riders an affordable way to gather precious power data with its Left Arm Power Meter Installation Kit for Consumer Supplied Cranks. Designed to pair with your current Shimano Dura-Ace, Ultegra, or 105 left crank arm, this kit provides single leg power readings to take your training to the next level without cleaning out your bank account. If you do decide to make the jump to dual-leg in the future, you're able to add Pioneer's drive side upgrade kit for the full compliment of power metrics. This system uses a strain gauge to measure pedaling force, direction, and overall efficiency as you ride, and it's right on par with industry standards at +/-2% accuracy. The power meter unit has a sleek profile on the inside of the crank arm, and only adds a claimed 22g to your frame. As you pedal, the sensors capture 12 points of rotation at 30-degree intervals, taking a measurement 16 times at each point to ensure accuracy. By recording information at multiple points, Pioneer is able to deliver a single accurate measurement that takes the entire pedal stroke into consideration.Riding through significant temperature or elevation fluctuations can wreak havoc on your power meter. Pioneer knows how frustrating it is to have to re-zero your device on-course, and how tough it is to recover momentum lost while you freewheel to let the unit zero. To address this common problem, it developed Zero Point Calibration with Active Temperature Memory Adjustment for its power meters. Essentially, the technology allows the power meter to anticipate and adapt quickly to environmental changes so that you don't lose access to accurate data when you need it most.The power meter is also compatible with ANT+, which makes using it with your favorite fitness apps or other ANT+ compatible devices simpl...

Pioneer Power Meter & Computer Color Kit Pioneer Power Meter & Computer Color Kit
One of the major criticisms Pioneer's new crankset power meters faced when first introduced was their extremely limited color palette, with cyclists lamenting whether mounting a power meter in Pioneer Red would ruin the carefully-curated aesthetics of their frames. We thought the criticism was justified, and so did Pioneer, so it created the Power Meter and Computer Color Kit, expanding the options for colors with pieces that cover the power meter and matching Pioneer computer. Not just choosing from a random list of colors, Pioneer matched the kit to pro team colors, and whether your favorite is among the chosen five or not, you can enjoy a range of colorful options that won't disrupt the clean style of your frame.

Pioneer Power Meter Installation Kit for Consumer Supplied Cranks Pioneer Power Meter Installation Kit for Consumer Supplied Cranks
If you're riding current generation aluminum crank arms but missed out on a powermeter model, then chances are good that the Power Meter Installation Kit for Consumer Supplied Cranks is your ride metric salvation. It adds data analysis to your alloy crank, letting you train smarter by analyzing your entire pedal stroke to help identify weaknesses and areas for improvement. The kit consists of a magical box, and the process is simple. Just drop your Shimano crankset into the box, drop the box in the mail, and wait for some seven to ten business days. During that time period, the alchemists at Pioneer will be transubstantiating your crankset from a shapely alloy article to a power-gathering data magnet. When the crankset returns to you, it will have a Pioneer power meter installed. Pioneer recently updated the original list of compatible cranksets, which was limited to Shimano Dura-Ace 9000 and Ultegra 6800. In addition to those two racing stalwarts, the powermeter installation kit now accommodates cranksets including the new Dura-Ace 9100, 105 5800, XTR Trail M9020, and XT M8000. The list also expands beyond Japan to include products engineered in Italy (Campagnolo Potenza), the US (Cannondale's Si and Si-SL2) and FSA's SL-K, a crankset whose ubiquity has made it a true citizen of the world.

Pioneer Right Side Power Upgrade Kit Pioneer Right Side Power Upgrade Kit
By splitting its complete power meter system into multiple, free-standing pieces, Pioneer essentially provided a gateway to get into the watts-measuring game gradually rather than dropping over $1,000 at once. The Right Side Power Upgrade Kit is actually just a box that, if you drop your drivetrain crank arm and chainrings in and ship it off to Pioneer, transforms your mundane crankset into a power meter-equipped data monster. Of course, the process isn't magical or mysterious at all. It's simple. While Pioneer has your drive-side crank arm, it will install a power meter sensor to it, and the only labor you need to worry about is re-installing the crank. The Right Side Power Upgrade Kit is perfectly capable of functioning as a stand-alone power meter; however, when combined with Pioneer's non-drive-side power meter, it opens the door for more accurate measurements by logging numbers for both legs rather than just doubling the readings recorded through a single crank arm. While the Single Leg system works well, the Dual Leg model takes your numbers and training to the next level.

Pioneer Shimano Dura-Ace 9000 Single Leg Power Meter Crank Arm Pioneer Shimano Dura-Ace 9000 Single Leg Power Meter Crank Arm
Since being introduced in 2013, Pioneer's crank arm power meters have become ubiquitous everywhere from T1 at a local triathlon to 86 podium appearances for the men and women of UnitedHealthcare Pro Cycling Team. Two years in, the technology is proven, but the huge metric-gathering, data-crunching capabilities that Pioneer built into it mean the entire system -- a Dual Leg Power Meter and Pioneer computer -- also comes with a huge price tag. The pros may need all of that extra information, but for a typical Cat 4 or a fitness-focused recreationalist, popping for the whole system may be overkill -- at least initially. The new Shimano Dura-Ace Single Leg Power Meter Crank Arm addresses these needs, providing a more affordable entrance to the world of Pioneer power metrics that leaves the door open for future upgrades. Upgrade path aside, the Single Leg Power Meter is an impressive piece of tech on its own, and since it broadcasts wirelessly with ANT+, chances are good that it's already compatible with your current head unit or wearable. It measures pedaling force, direction, and overall efficiency by monitoring 12 points of rotation at 30-degree intervals across the pedal stroke. At each point, the deflection caused by radial and tangential forces on the crank arm is scanned 16 times to ensure a claimed +/-2% accuracy. The system's Active Temperature Memory Adjustment feature maintains that accuracy in temperatures ranging from 14 to 122 degrees Fahrenheit, so it stays on point even in extreme conditions. This eliminates the need to freewheel in the middle of a race in order to zero the system, a situation that can cost you precious momentum during a solo effort or make you lose your safe position near the front just as the race hits a climb. The unit also has a waterproof rating of IPX6 and IPX7, so it can handle inclement conditions as well as extreme temperatures. The system uses Shimano's top-tier Dura-Ace crank arm as a platform, matching the meter's unmatched...

Pioneer spent the past three years working with pros to continuously improve upon its first power meter offering, testing its technology with riders who depend on reliable, accurate measurement systems. The latest version, the Shimano Ultegra 6800 Single Leg Powermeter Crank Arm, provides you with an efficient way to chart your performance and improve upon your training whether you're looking to podium in your next tri or dominate the local time trial series. Rather than requiring you to invest next month's mortgage to gain access to power data, Pioneer offers the Single Leg model as a more affordable introduction. As your training and ambitions progress, you can easily upgrade to Pioneer's complete power meter setup to track more detailed, in-depth measurements, but the single leg power meter will tell you everything you need to get started. This system uses dual strain gauges to measure pedaling force, direction, and overall efficiency as you ride, and it's right on par with industry standards at +/-2% accuracy.

PowerTap G3 AMP 35 Carbon Clincher Wheelset PowerTap G3 AMP 35 Carbon Clincher Wheelset
The PowerTap G3 Amp 35 Carbon Clincher wheelset brings together two pieces of kit that are always appropriate for any occasion in the saddle. The Amp carbon rim (actually a re-branded Reynolds) 35mm depth is ideal for virtually any conditions you might encounter. It excels on alpine climbs, sweeping descents, chip seal and stones, and long days spent alone in the wind, making 35mm the most versatile choice for a cyclist looking for aerodynamic advantages with a one-wheel quiver. The real draw of the wheelset is the diamond in the rear hub, though, PowerTap's own G3 power meter, which ensures that your efforts will be appropriately metered and monitored across a long day of effort in the saddle. Obviously, the G3 rear hub doesn't actually involve diamonds, but it does feature eight strain gauges and a claimed +/- 1. 5% accuracy rating -- solid gold numbers that continue to set the industry standard. As you send watts down to the pedals, the G3 sends these numbers up to the head unit via the ubiquitous ANT+, so chances are good that your current head unit is already compatible with it. Changing the battery, updating firmware, or servicing the unit can all be effected in minutes with the use of PowerTap's handy little tool, making this one of the most home mechanic-friendly power meters on the market. As we noted above, the Amp rim is actually built buy Reynolds but with some PowerTap branding laid over the top. The result is a price drop in the four-digit range when compared with G3-equipped carbon hoops from manufacturers whose decals add a premium to cost. The wheels are anything but bargain bin, though. In addition to the depth's versatility, the Amp 35s feature the same slightly rounded spoke face that's become so common across the industry for its ability to temper the violent lateral forces of crosswinds and yaw angles. The rims also adopt the increased width of more expensive models, sitting at a healthy internal width of 17mm. Wider rims increase structur...

Quarq DFour Power Meter Crank Arms - BB30 Quarq DFour Power Meter Crank Arms - BB30
Though Quarq is technically part of the SRAM family (SRAMily' No, we wouldn't do that to you.), the BB30 DFour Power Meter Crank Arms prove that the brand doesn't take a Hatfield/McCoy approach to inter-brand compatibility. The DFour is, essentially, the DZero model but with one fewer chainring bolts and a bolt circle diameter (BCD) that fits Shimano's latest generation of 11-speed road chainrings, specifically Dura-Ace 9000, Ultegra 6800, and 105 5800. That means that, with the exception of the latest Dura-Ace 9100, the DFour is compatible with every 11-speed road drivetrain Shimano has engineered to date, so fans of the Japanese company aren't relegated to choosing between more expensive or less accurate power meter options. The BCD may be Shimano, but the crank arms themselves are all SRAM. They're built with the same Exogram construction process used in the brand's top groupsets, so they're around 200 claimed grams lighter than the aluminum model. The BB30 version of the DFour also ships with the spacers and wave washer hardware required to install it in a BB386EVO bottom bracket--a bottom bracket standard that the aluminum DZero isn't compatible with. Except for that compatibility difference, the DFour incorporates every piece of technology Quarq crams into the DZero. Chief among these is the power meter itself, which saw a healthy amount of retooling. Overall, Quarq claims that "150 documented improvements" inform the evolution from the previous models to DFour, but the most important is to the heart of the meter itself: the strain gauges and measurement circuitry. It still incorporates five strain gauges strategically placed throughout the spider in order to measure the Newton meters you're throwing into the pedals. It's also still got the same claimed accuracy of +/- 1. 5%, so its numbers are 0. 5% more accurate than most meters, but the new design requires less correction in order to maintain accuracy in drastic temperature changes.

Quarq DFour Power Meter Spider Quarq DFour Power Meter Spider
The DFour Power Meter Spider is for cyclists already equipped with a Quarq Elsa RS eight-bolt power meter who are interested in the improved functionality of Quarq's latest, DZERO technology. This smart spider lets you keep the components from Quarq (spindle and crank arms) and Shimano (chainrings) that you're currently using, letting you upgrade to more precise power data without forcing you to toss perfectly a perfectly good crank chassis. If you've got the Prime crank and want to up your training/competitive game, then the upgrade makes obvious sense. If you're already rocking a previous generation of Quarq's 8-bolt powermeter spider, then the reasons are, admittedly, less compelling, and are defined by the internal changes Quarq made to the meter. Of these, the most important is to the heart of the meter itself: the strain gauges and measurement circuitry.

Quarq Elsa R Power Meter Crank Arms - BB30 Quarq Elsa R Power Meter Crank Arms - BB30
For competitive riders looking to maximize every watt in training and racing scenarios, the Quarq Powermeter BB30 Elsa R Power Meter Crank Arms use SRAM's Exogram hollow carbon crank arms for uncompromising stiffness and power transfer. They're compatible with road bikes fitted with a BB30 bottom bracket interface and SRAM's 10 and 11-speed chainrings/groups (both Yaw and non-Yaw). The Elsa R measures power at the crankset spider with Quarq's OmniCal power measurement for greater precision. In fact, you'll find its spider-fitted power meter delivers +/- 1. 5% power accuracy readings, as well as power measurements along both the left and right cranks with its Power Balance Technology. This is crucial in evaluating weaknesses in both legs when you're looking to improve your training and racing times. Another benefit, as opposed to chainring-dependent power meter cranks, is the ability to swap out chainrings to better suit your riding needs and local terrain. Communicating with ANT+ cycling computers, the Elsa R wirelessly transmits power and cadence data to popular cycling computers, such as Garmin's Edge 500, 510, 800, 810, 1000, and Forerunner 910XT models. It's also compatible with TrainingPeaks WKO+, TrainingPeaks, Golden Cheetah, and Strava cycling apps. Furthermore, you'll find its replaceable CR2032 battery lasts some 300-hours of riding time, while its IPX-7 rating ensures protection from heavy showers and soaking road spray.

Track your training progress on the road, gravel, or cyclocross course and get the most out of every ride. To get the most accurate data, Quarq measures power at the spider in the heart of the crankset, capturing data at the transfer point between the crank arm and chainring. With a +/- 1. 5% accuracy window, rest assured that you're getting the right readings to keep your training on track. Quarq has also addressed the pesky issue of temperature changes wreaking havoc on power measurement accuracy. The Riken AL comes with Quarq's 10K temperature compensation technology, the result of an extensive programming process that uses over 10,000 data points to facilitate accurate power measurement regardless of temperature. 10K temperature compensation is factored into every pedal stroke for continuous and consistent power readings. Tackle those high mountain passes and hot summer rides with confidence that your ride files will accurately reflect every watt you put into the pedals -- no need to stop and re-zero along the way. The Riken AL measures cadence with an AxCad accelerometer, which means there won't be any unsightly magnets hanging off the frame to capture pedal rotations. An LED light on the face of the spider provides information for setup, and ANT+ ID lets the power meter recognize your specific head unit for quick installation and easy operation. We don't recommend taking these crank arms swimming, but in case you overshoot a corner and end up in a winding mountain stream, the Riken AL has an IPX7 waterproof rating, meaning they'll survive submersion in up to one meter of water for 30 minutes.

The CR2032 gives you up to 300 hours of ride time, and when do you have to replace it, you can do it yourself, without any tools-- this is far better than having to mail it back to the manufacturer, which is what most systems require. To boot, Quarq designed the Riken R to be waterproof for 30 minutes while submerged under one meter of water. To communicate data to your head unit, the Riken R uses ANT+ wireless so your current computer is most likely already compatible with it. The Riken R uses an AxCad accelerometer to measure cadence, and it's compatible with various training software such as Training Peaks WKO+, Golden Cheetah, and Strava. This model is compatible with BB30 bottom brackets and SRAM 10- and 11-speed and Shimano 10-speed drivetrains. For 11-speed Shimano compatibility, check out the Elsa RS model.

Quarq SRAM Red DZero Power Meter Crank Arms - BB30 Quarq SRAM Red DZero Power Meter Crank Arms - BB30
For the self-sponsored racer who uses multiple bikes in different disciplines, the powermeter game can turn into an exercise in astronomic expenditure. Quarq's SRAM Red DZero Power Meter Crank Arms address economic concerns by combining every key piece of powermeter technology in Quarq's stable with a redesigned measurement circuit, the same relatively attainable price that defined the new system's predecessors, and the ability to quickly swap between frames and chainrings for omniums. The result is an uncompromising platform whose less-capable predecessors were ridden to sprint victories, solo stage wins, and grand tour podiums by Katusha and Ag2r-La Mondiale in 2016 alone. Since the Red DZero represents an improved version of that model, we're eager to see what it can do this year in both the peloton and our own bottom brackets. As with the rest of the DZero line, the Red model still incorporates five strain gauges strategically placed throughout the spider in order to measure the Newton meters you're throwing into the pedals, and--except for the alloy spider--it features the same Exogram carbon crank arms and graphical treatment as the standard Red crank. It's also still got the same claimed accuracy of +/- 1. 5%, so its numbers are 0. 5% more accurate than most meters, but the new design requires less correction in order to maintain accuracy in drastic temperature changes. Fewer corrections mean the latest SRAM Red power meter model also better rations battery life than the previous generations, though when the battery does go out, you can still change it without tools or having to ship the whole thing to the manufacturer. The Red DZero system's accuracy is further boosted by the return of Quarq's 10k dynamic temperature compensation technology, which alleviates the need for constant, mid-race zeroings in variable conditions. Even if it's just coasting for a few seconds or toggling through your head unit to the proper option, it can still be the difference be...

Quarq SRAM Red Power Meter Crank Arms - BB30 Quarq SRAM Red Power Meter Crank Arms - BB30
You've been hearing about the benefits of training with a power meter from your ride buddies for a few years now, and we don't blame you if you've found it exhausting to sort through the plethora of hyperbole from manufacturers claiming to have the best power meters on the market. For whatever reason you've found yourself here, looking at Quarq's SRAM Red BB30 Power Meter Crank Arms, and we can say that if you'd like to blend a self-sponsored price tag with pro-level training functionality, this power meter is the place to start. Any power meter will employ a slightly different "thinking" mechanism to actually measure watts, and in the case of the Red Power Meter, the thinking is carried out by five strain gauges strategically arranged throughout the Exogram Hollow spider. They continuously work to measure the Newton meters you're driving into the pedals, and they do so with a claimed accuracy of +/-1. 5%, which is 0. 5% more accurate than many meters on the market. Quarq decided to make them ANT+ compatible as well, so you won't have to deal with swapping out head units or wearables to adapt the crank arms to your existing setup. Taking into account that most of us have a stronger leg, the SRAM Red crank arms use proprietary Power Balance technology to chart the power you're generating in both crank arms separately, giving you the advantage of being able to analyze weak spots in each leg as you ride familiar climbs and tackle grueling interval sets. Rather than include a battery setup that requires a full range of tools or needs to be mailed in to be changed, the batteries on the Red crankset have over 300 hours of life, and once they run out, they require no tools to be swapped for a fresh battery. One of the most notable features of the Red crank arms is their 10k dynamic temperature compensation feature, which was developed to address power meters' weakness in the face of rapidly rising or falling temperatures. Having to stop and back-pedal in the middle o...

Quarq SRAM Red Power Meter Crankarms - GXP Quarq SRAM Red Power Meter Crankarms - GXP
Step up your training game with industry-leading accuracy and data tracking ability with the Quarq SRAM Red Power Meter GXP Crankarms. Featuring the same Exogram hollow construction as the standard Red crank arms, these cranks track power data with a claimed accuracy of +/- 1. 5% so you can get the most out of every ride. The Red Power Meter Crank arms communicate via ANT+ connectivity protocol, which makes them compatible with most head units. Power Balance technology means each crank arm gets charted separately so you can analyze the balance in your pedal stroke to identify any weaknesses and get to work improving them. It also measures cadence with an AxCad accelerometer, and it's compatible with various training software such as Training Peaks WKO+, Training Peaks, and Golden Cheetah.SRAM addresses the tendency of elevation and temperature changes to wreak havoc on accuracy with its 10K dynamic temperature compensation feature. By mapping an estimated 10,000 data points to record how the unit responds to temperatures ranging from zero to 130 degrees Fahrenheit, which, in real world terms, means this meter will read consistently no matter where you ride without annoying stops to re-zero and recalibrate along the way.Keeping with the weather theme, SRAM made a point to ensure this power meter can endure extreme conditions. It'll survive being submerged under one meter of water for 30 minutes, and while we can't recommend taking it swimming, you can rest assured it'll come out the other side of a mid-mountain dip in a stream after a mis-timed turn.Out of all its features though, our favorite may be the ability to change the system battery yourself. Other systems require you to mail in your crankset for battery swap-outs, but the Red model runs on an easy-to-find CR2032 battery and boasts a tool-free user replacement system as well as a predicted 300+ hours of ride time per battery for more time in the saddle.

Quarq SRAM XX1 Eagle DZero Power Meter Crank Arms - BB30 Quarq SRAM XX1 Eagle DZero Power Meter Crank Arms - BB30
Quarq introduces the SRAM XX1 Eagle DZero Power Meter BB30 Crank Arms by noting that they embody every piece of Quarq technology produced during the past decade of powermeter R&D. With the latest XX1 model, all of that technology is paired with hollow Carbon Tuned XX1 crank arms, which can safely be dubbed the epitome of the last decade of SRAM's R&D. Unlike the standard XX1 Eagle and vanilla XX1 cranksets, which are direct-mount, the DZero Eagle features a four-bolt spider compatible with an X-Sync 2 or X-Sync 104 BCD chainring, depending on your drivetrain. We do like the simplicity and modularity of the direct-mount chainring design, but the powermeter's strain gauges and electronics live in the spider, so eliminating it isn't an option in the Quarq system. As with the rest of the DZero line, the XX1 model incorporates five strain gauges strategically placed throughout the spider in order to measure the Newton meters you're throwing into the pedals, and--except for the alloy spider--it features the same Exogram carbon crank arms and graphical treatment as the standard Red crank. It's also still got the same claimed accuracy of +/- 1. 5%, so its numbers are 0. 5% more accurate than most meters, but the new design requires less correction in order to maintain accuracy in drastic temperature changes.

Quarq SRAM XX1 Power Meter Crank Arms - BB30 Quarq SRAM XX1 Power Meter Crank Arms - BB30
Power meters aren't just for roadies anymore. The Quarq SRAM XX1 Power Meter Crank Arms are specifically designed for BB30 systems with a CNC-machined aluminum spider that houses the power meter. Five strain gauges, placed strategically throughout the spider, measure the Newtons applied to the pedals. With a claimed accuracy of +/- 1. 5%, the SRAM XX1 Power Meter Crank Arms effectively and accurately take your training to the next level. The Quarq Power Meter communicates with your head unit via ANT+ wireless. That means there's a good chance that it's compatible with your existing system. The Power Meter also features Quarq's proprietary Power Balance technology, which measures and displays the power that you're generating in both crank arms separately, so you can determine which leg you're getting more power from, and thereby tweak your training program to even things out. Another nice feature with the Power Meter is the tool-free battery replacement, so you can swap the batteries and go riding, rather than pulling your cranks off the bike and mailing them in for a replacement. One ongoing issue with power meters is their susceptibility to fluctuating temperatures, where rapidly rising or falling mercury necessitates one or more mid-event zeroings. The XX1 Power Meter now addresses this with a dynamic temperature compensation that includes over 10,000 data points. It figures out the atmospheric details for you with minimal drift, so you can focus on turning the cranks, not babying them.

SRM Campagnolo 4-Bolt Powermeter Crankset SRM Campagnolo 4-Bolt Powermeter Crankset
SRM pioneered the crank-based power meter way back in 1987, and has continued to set the standard by which the rest of the industry follows ever since. The SRM power meter boasts an exceptionally precise accuracy window of less than one percent, making it the virtually unassailable bench mark for measuring power in research settings. Paired with Campagnolo's carbon fiber crank arms, the SRM Campagnolo 4-Bolt Powermeter Crankset delivers impeccable power transfer, accurate measurement, and a dash of Campy style. But don't take our word for it; just watch the final two mountain stages of 2016's Giro to see what a guy like Nibali can do with this here crank apparatus. SRM measures torque with four measuring bridges along the spider in the heart of the crankset to capture data at the transfer point between the crank arm and chainring, which is then plugged into an equation along with pedal velocity to determine power output. With a less than +/-1% accuracy window and a reading range of zero to 4,200 watts, rest assured that you're getting the right readings to keep your training on track. Although the crankset looks strikingly similar to Campagnolo's standard Record crank, it does have some differences. SRM worked with Campagnolo to develop a custom carbon fiber crank arm that integrates seamlessly with the SRM spider. Despite this necessary difference, the SRM Campagnolo crankset still features the renowned Cult bearings, which Campy claims enjoy 3. 5 watts of improved pedal efficiency with each pedal stroke and the lowest coefficient of friction available courtesy of the perfection of ceramic bearings and Campy's top-tier races. The crank arms are essentially Record crank arms minus the Record spider, so they're made with the same Ultra-Hollow technology to deliver exceptionally light weight yet impeccably stiff power transfer. The SRM Campagnolo 4-Bolt Powermeter Crankset was designed to pair with SRM's separately sold Powercontrol head units, but is also comp...

SRM Dura-Ace 9000 Wireless Powermeter SRM Dura-Ace 9000 Wireless Powermeter
This version of the SRM Power Meter features a larger diameter than Shimano's 7900 version. This adequately accommodates the larger FC-9000 crankset. In addition to allowing the crankset to fit properly, the new platform also provides more accurate measurement of the offset forces and torque patterns for your left versus right leg, which means more accurate overall power measurements. The wider diameter holds two batteries, which equates to almost 3,000 hours of use before needing to be recharged. SRM uses its tried and true eight strain gauges for measuring data. The 9000 Power Meter features an accuracy of +/- 2. 0% between 30 and 255 rpm, with a wattage range between 0 and 4096 watts, for that wild finishing sprint. The FC-9000 crank is the same Dura-Ace crank being touted for its versatility. You're able to run compact or standard rings on the same spider. Thanks in part to the four arm design, it is also lighter than, but just as stiff as, its predecessor. It uses Shimano's Hollowtech II and Hollowglide technology to create a stiff yet lightweight design with an unrivaled weight-to-stiffness ratio.
