The SRAM Quarq AXS Aero Power Meter Kit makes use of a unique direct mount aerodynamic X-SYNC chainring with an integrated Quarq Dzero power meter that improves aerodynamic performance, while providing impeccable chain retention and accurate power measurement. Unique one-piece chainring design features a built in Quarq Dzero Power MeterPower meter is accurate within +/- 1.5% and balances power between left and right leg separatelySingle chainring design simplifies functionality and reduces weightX-SYNC chainrings provides impeccable chain retention8-bolt direct mount interface - only compatible with SRAM Red D1 and Force D1 cranksThe X-Sync chainring features a special laser-etched finish that is more durable, improving the usable life of the chainring; this isn't just for race day only. The unique X-Sync narrow-wide too profile is not only supremely efficient and durable, but it also provides impeccable chain retention. Unlike other SRAM chainrings, the Quarq AXS Power Meter uses a unique 8-bolt direct mount interface that is only compatible with SRAM Red D1 and Force D1 cranks.The integrated Quarq Dzero is cleverly packaged as part of the chainring, reducing weight and making it possible to switch the power meter between compatible Red chainsets. The power meter has a power balance feature, that measures power from left and right legs separately and is accurate within +/- 1.5%, giving a highly accurate reading to help you train and ride harder.

The SRAM RED AXS™ power meter breaks with tradition — and breaks through to new levels of performance. We reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. We also maintained a 13-tooth delta on all chainring pairs, ensuring precise shifting for any setup. This results in more useful gearing and better shifting across all configurations. Our power meters are also designed with Quarq’s premier DZero™ power measurement technology fully integrated into the crankset. Welcome to the pinnacle of the power meter. Features: X-Range™ gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear Integrated power measurement Power meter is fully integrated into the chainring set for lighter weight Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride Power balance measures left and right legs separately Improved front shifting performance for crisp and accurate front shifts Unique chainring shape results in a lighter weight, stiffer, more durable crankset Integrated chainring design significantly reduces weight DUB™ bottom bracket adds durability, simplicity and broad compatibility Specifications: Speeds: 12 Crank arm length: 170mm, 172.5mm, 175mm, 177.5mm BB Compatibility: All SRAM Road DUB BBs Chainring Size: 46/33, 48/35, 50/37 Bolt Circle Diameter (BCD): Direct Mount (DM) Chainline: 45.0mm BB Spindle Interface: DUB Chainring material: Aluminum Guard: No Guard Crank arm material: Carbon Color (Crank arm): Natural carbon Power Meter Type: ANT+ and BLE

Shimano Dura-Ace R9200 12 Speed Power MeterWith a rechargeable battery and Bluetooth LE and ANT+ connectivity, the Shimano Dura-Ace FC-R9200-P power meter is a user-friendly training partner. A vital tool for serious cyclists, this model delivers reliable, waterproof, dual-sided power measurement. Bluetooth LE and ANT+ ConnectivityThe Dura-Ace FC-R9200-P power meter brings everything a data-driven cyclist could want. Its integrated, waterproof design brings all-weather reliability while delivering accurate information including left/right balance. A rechargeable Li-ion battery is user-friendly and Bluetooth LE and ANT+ connectivity ensure easy setup.Hollowglide Chainring TechnologyWith hollow technology on the outer chainring, its Hollowglide construction ensures high rigidity while its hollow structure cuts down on weight yet maintains strength. This provides better power transfer and quicker and more precise front shifting performance.Hollowtech II Forged Crank ArmsA lightweight crankset not only reduces your bike's weight but decreases rotating mass to aid in acceleration. The challenge is to reduce the weight of the crank without reducing its strength and rigidity.Shimano's advanced forging technology has solved the problem through the Hollowtech crank. Just like high-quality frame tubing, a hollow crank arm can provide amazing strength and rigidity at a very lightweight.The Best Balance of Stiffness, Strength and WeightThe concept of Hollowtech II technology is focused on producing a superior crankset that will maximise your power transfer. The rigidity of the crankset ensures pedalling efficiency while its low weight, a key element of the crankset, aids in cycling longer distances over which you need to pedal more. Naturally, Shimano strove for the optimum balance between the conflicting needs of stiffness while producing a lightweight crank.The addition of Hollowtech II technology integrates the bottom bracket axle with the right crankarm for more stiffness and weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedalling stability, allowing for more efficient power transfer.The Shimano Dura-Ace R9200 12 Speed Power Meter has been developed by pursuing the optimum balance of stiffness & rotating performance in a lightweight and beautiful crankset design.Features: Series: DURA-ACE R9200 Series Integrated, waterproof, and rechargeable Li-ion battery Up to 300+ hours of ride time *Depending on ANT+/BluetoothLE settings Accurate data collection 1.5% strain gauge accuracy throughout the entire calibration range *Depending on ANT+/BluetoothLE settings Proprietary strain gauge Possible to start quickly Simple zero offset calibration with switch on the transmitter Active temperature compensation The software automatically compensates for temperature changesA 2-year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).Buy Shimano Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
