Kreisā kloķa svira ar jaudas mērītāju Stages Power L Shimano Ultegra R8100 (U81L)-172.5MM U81L-D
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. Stages Power L (left-sided only) is built on to a non-drive side Shimano ULTEGRA R8100 crank arm and is compatible with all frames that fit Shimano Hollowtech II cranks. 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. 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.
