Stages Cycling Power L Power Meter Crank Arm for Shimano Ultegra R8000

The Stages Power meter is built on to a non-drive side Shimano Ultegra R8000 crank arm, is compatible with all frames that fit Shimano Hollowtech II cranks and impresses with its low additional weight of only 15 grams.

With an accuracy of +/-1.5 %, an integrated accelerometer for measuring cadence and an active temperature compensation as standard function, the Stages Powermeter also impresses with its simple handling. For Shimano models you can also choose between a single-sided or dual-sided power measurement system. Via Bluetooth Smart and ANT+, the Stages Power can be connected to all common head units (Garmin, Polar, Sigma, Suunto, Wahoo, and others) as well as to smartphones in seconds.

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.

Active Temperature Compensation as standard equipment
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.

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. Individual calibration for the dual-sided option means that you can trust the data produced by our system, as it's a real measurement and not an estimation.
