Stages Cycling Power L Power Meter Crank Arm for GRX RX810

The Stages Power L Powermeter is pre-assembled on a Shimano GRX M810 left crank arm and is suitable for all frames that are compatible with Shimano GRX Hollowtech II cranks.

Tour proven:
Stages Powermeter have accompanied athletes on their way to three consecutive Tour de France victories and many national and world championship titles. If racing is seen as the toughest test bench for the best products, the Stages Powermeter has proven to be the best powermeter.

Active temperature compensation (ATC) as standard function:
Providing consistent performance data is the most important function of a power meter. The Stages Powermeter was the first power meter to implement temperature compensation as an automated process, ensuring accurate measurements under any environmental conditions. ATC is the central key factor for accurate power measurement and the reason why athletes can always rely on Stages Power.

Independent calibration for maximum precision measurement:
Each Stages Powermeter is calibrated individually. This ensures a +/-1.5% measurement accuracy and is the industry best value for non-scientific power measurement systems.
