Stages Cycling Power L Powermeter | Crank Arm by Shimano - Ultegra R8100

Stages Powermeters are the perfect upgrade when it comes to significantly improving performance on the bike. The high-resolution Gen 3 Powermeter technology benefits from more than a decade of continuous product innovation.

In the Power L model, the pre-mounted sensor on the left crank arm measures the cyclist's wattage values with maximum accuracy. Data transmission is seamless via Bluetooth and ANT+. The powermeter sensor itself integrates seamlessly into the design of the Shimano Ultegra FC-R8100 crank arm with Hollowtech II technology and only adds 15 grams to the weight.
