The ULTEGRA FC-R8100-P Powermeter crank offers the complete range of functions and the same precision as its DURA-ACE counterpart, but at a more attractive price.
Training under scientific conditions requires precise measurements, but also ease of use. The new ULTEGRA R8100 powermeter crank excels at both. Its bilateral measurement is accurate to within 1.5%, and zero calibration is quick and easy. Perhaps most importantly, however, is its long battery life, easy charging, and ANT+ and Bluetooth®LE connectivity, making it easier than ever to record and use training data.

< 1.5% Powermeter accuracy throughout calibration range * Depends on ANT+/Bluetooth®LE settings.
