Stages Cycling is mounted on a Shimano Ultegra R8100 crank arm on the drive side and is compatible with all frames that fit Shimano Hollowtech II cranks.
Product highlights
-
Tour de France tested : Stages Power has led riders to three consecutive Tour de France wins and many other world and national championships. If you think racing provides the best testing ground in the world, then Stages Power is the best power meter in the world.
-
Active Temperature Compensation (ATC) 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 regardless of environmental conditions. ATC is the main reason a rider can trust Stages Power's data in any condition.
-
Individual Meter Calibration for More Accurate Results : Each Stages Power sensor is individually calibrated to ensure an accuracy level of +/- 1.5%, which is the best accuracy level in the industry for non-scientific sensors.
