Offering all the precision and functionality of the DURA-ACE power meter, the ULTEGRA FC-R8100-P power meter comes in a more affordable package. Scientific training requires accurate measurement and user-friendliness, and the new ULTEGRA R8100 power meter has both. Its dual-sided measurement is accurate within 1.5% and zero offset calibration is a quick and easy process. Perhaps most importantly, its long battery life, easy recharge, and ANT+ and Bluetooth®LE connectivity makes using and recording your workouts easier than ever. Integrated, waterproof, and rechargeable Li-ion battery - Up to 300+ hours (TBD*) of ride time * Depending on ANT+/Bluetooth®LE settings Accurate data collection - ±1.5% (TBD*) strain gage accuracy throughout the entire calibration range * Depending on ANT+/Bluetooth®LE settings - Proprietary strain gauge Possible to start quickly - Simple zero offset calibration with switch on transmitter Active temperature compensation - Software automatically compensates for temperature changes

The SRAM RED AXS power meter breaks with tradition — and breaks through to new levels of performance. SRAM reengineered road gearing: reducing front chainring size and adding more range to the rear cassette. They 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. These 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. - 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 - Speeds: 12 - BB Compatibility: All SRAM Road DUB BBs - BB Spindle Interface: DUB - Chainring material: Aluminum - Crank arm material: Carbon - Power Meter Type: ANT+ and BLE - Bottom bracket not included
