Stages Gen 3 Ultegra R8100 Left Side Crank Power Meter

Non-Drive Side Powermeter Crank Arm

This is the new single-sided Stages Power L meter built on to a non-drive-side Shimano Ultegra R8100 crank arm and is compatible with all Shimano Hollowtech II road drivetrains. This new meter is founded on Stages Power technology, including Stages' defining Active Temperature Compensation feature in a package that offers the most technical cyclist the data they crave. When combined with the Stages Performance Ecosystem of Stages Link and Dash, Stages Power L gives additional data that the most advanced cyclists need to bring out their best performance.

Individual Meter Calibration for the Most Accurate Results

Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters.

Active Temperature Compensation

Consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions.

Tour Proven

Stages Power has carried riders to three consecutive Tour de France victories, plus many more world and national championships. If you believe racing provides the world's best product proving ground, then Stages Power is proven as the world's best power meter.
