Stages Cycling Power R Power Meter Crank Arm 39/53T for Shimano Dura-Ace R9100

The STAGES CYCLING Power R Powermeter crank will delight competitors and cyclists who want to train precisely to improve their performance. It is used in particular by Team Sky riders, including Christopher Froome and Geraint Thomas, winner of the last Tour de France. This straight crank offered here in the Shimano Dura-ace 9100 version with powermeter is only 20 grams heavier than the version of the Japanese manufacturer. This crank features a further improved precision of +/- 1.5% thanks to four strain gauges positioned along the entire length that detect the smallest deflection of the crank and thus determine the power. The crank also includes an internal cadence sensor based on an accelerometer coupled with a gyroscope. All data is then transferred to your computer or smartphone thanks to dual Bluetooth and ANT+ connectivity and used directly via the StagesPower app to create your training plans and analyse your performance.

Important information:
The integrated sensor on the crank has a thickness of approx. 5 mm. Before mounting, check that the distance between the crank and the frame is greater than 5 mm.
