Stages Cycling Power R Power Meter Crankset 52/36T Shimano Ultegra R8100

Stages Power R is pre-mounted on the drive side of a Shimano Ultegra R8100 crank and is suitable for all frames compatible with Shimano Hollowtech II cranks.

With a measuring accuracy of +/-1.5 %, an integrated acceleration sensor for measuring the cadence and active temperature compensation as a standard function, the Stages Powermeter also impresses with its easy handling. Especially for Shimano models, you can also choose between one-sided or two-sided power measurement. Via Bluetooth Smart and ANT+, the coupling with all common bike computers (Stages, Garmin, Polar, Sigma, Suunto, Wahoo, etc.) or smartphones is done within seconds.

Tour tested
Stages power meters have accompanied athletes on their way to three Tour de France victories in a row and many national and world championship titles. If you look at racing as the toughest test bench for the best products, the Stages Powermeter has proven to be the best powermeter.

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