Precision Training and Dura-Ace Trickle-Down Functionality in an Ultegra Package
Offering all the precision and functionality of the DURA-ACE power meter, the Ultegra FC-R8100-P power meter crankset comes in a more budget-conscious 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.
The R8100 features an integrated, waterproof, and rechargeable LI-ion battery with up to 300+ hours of ride time depending on Bluetooth mode and settings. The unit's software automatically compensates for real time temperature changes.
