Stages Cycling Power LR Power Meter Guarnitura 50/34T Shimano Dura-Ace R9200

Stages Power LR is pre-mounted on both the left crank arm and the drive side of a Shimano Dura-Ace R9200 crankset and measures power values of the left and right leg independently.

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.

Independent calibration for maximum precision measurement
Each Stages Powermeter is individually calibrated. This ensures +/-1.5% measurement accuracy and is the 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.
