Stages Cycling Power L Power Meter Crank Arm for XT M8100/8120

The Stages Power L is pre-assembled on a left Shimano XT M8100 crank arm and is suitable for all frames that are compatible with Shimano 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.

Stages Power R for additional compatibility or the possibility to upgrade an existing Stages Power L to a Stages Power LR:
Although this is not a common problem, there are some bicycle models (e.g. Cervelo P5 or others with Direct Mount brakes or boost standard) where the Stages Power L is not compatible with the frame/brake due to interference from the power meter housing. The Stages Power R provides enhanced compatibility with these models. It also opens up the possibility of upgrading existing Stages Power L to Stages Power LR (double-sided) systems.
