Stages Cycling Power LR Set Biela Power Meter 50/34T Shimano Ultegra R8100

The Stages Powermeter LR is pre-mounted on both the left crank arm and the drive side of a Shimano Ultegra R8100 crankset, measures power values of the left and right leg independently and impresses with its low additional weight of only 35 grams.

With a measurement accuracy of +/-1.5%, an integrated accelerometer for measuring cadence and active temperature compensation as a standard feature, the Stages Powermeter also impresses with its easy handling. Especially for Shimano models can additionally be selected between a 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, and many more) 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 bed for the best products, the Stages Powermeter has proven to be the best powermeter.

Active temperature compensation as a standard feature
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 central key factor for accurate power measurement and the reason why athletes can always trust Stages Power.

Independent calibration for maximum precision measurement
Each Stages powermeter is individually calibrated. This ensures +/-1.5% measurement accuracy and is industry best for non-scientific power measurement systems. Individual calibration on the Stages Power LR means that the output power data from both sides are real measured values and are not estimates.
