The SRAM Quarq AXS Aero Power Meter Kit makes use SRAM's new X-Range gearing technology, offering smoother shifting and a wider gear range. The rings are combined with an integrated Quarq Dzero power meter that provides accurate power measurement.

Quarq DZERO Road Power Meter ChainsetFeaturing two high-quality carbon crankarms, this powermeter offers exceptional stiffness, strength and low weight performance on your road bike. Quarq has also equipped this model with two SRAM X-Glide aluminium chainrings for additional durability and precision as you clock up the miles. Designed for compatibility with most 10 speed and 11 speed drivetrains, this powermeter is fitted with a Quarq DZERO DUB spider power meter that delivers accuracy within 1.5%, measuring both legs. Another highlight is it comes complete with many of Quarq's renowned technologies such as MagicZero, AxCad and OmniCal as well as 10K Temperature Compensation and an IPX7 waterproof rating for accuracy and consistency in any weather conditions. DZERO Road Powermeter with X-Glide ChainringsImagine being able to shift smoothly at any time, no matter what. We're talking full-power shifts. Up, down, whatever the road demands. The benefit of X-Glide chainrings is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you'll never again compromise your speed and power in unpredictable road conditions. Quarq precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin—rather than the middle of the chain link—you get double the shift opportunities. No more missed shifts, ever. X-Glide puts you in the right gear, right now.Bluetooth and ANT+ CompatibleYour riding and training efforts deserve power measurement that reaches the highest standards of accuracy to help you reach personal records. Because without accurate data, you can't know if you are making the progress you're aiming for. With Quarq's premier DZero power measurement technology that uses Bluetooth and ANT+ connectivity, you'll have the technology to get real results.Reach new goals and explore new roads with a power meter that delivers on accuracy, durability, and reliability. The Quarq DZero DUB Power Meter is paired with the Quarq DUB Crankarms and SRAM's X-Glide 52/36t chainrings to have the perfect fit for most 10- or 11- speed groupsets.

This SRAM AXS app allows riders to see battery status, change component behaviour, personalise controls, get maintenance reminders and update firmware. X-SYNC: SRAM X-SYNC chain rings provide the highest level of performance and durability. The SRAM X-SYNC tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC rings are an integral part of the SRAM 1x drivetrain. DZERO: The Quarq platform for powermeters, DZero, is certified according to the DZero experiment, one of the most accurate and innovative Projects of science to study subatomic particles moving at the speed of light. With a new measuring circuit, a revised DMSDesign, improved accuracy throughout the entire Pedal rotation and software progress represented DZero represents the state of the art in power measurement technology.Buy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.

Building on what it learned with its Gen 2 Version, Stages has developed its technology even further for this latest model. Built on to a Shimano Dura-Ace R9100 crankset, it measures the power output of each of the rider's legs and the crankset is individually calibrated to ensure its accuracy. Stages produce power meters that both avid amateurs and professionals at the top of their game can trust. Reliable Readings In All Conditions To ensure consistency of measurement, Stages introduced a world-first feature to its power meters. This feature is called “Active temperature Compensation” and it is built in as standard to account for sudden temperature changes, which if not accounted for, would result in false and inaccurate data. Stable Connection Stages have made additional improvements to the Bluetooth and ANT+ transmitters and the accelerometer. This ensures a stable and powerful connection with your cycle computer is maintained and a faster sampling rate for more up-to-date feedback on your performance.
