The new Gen 3 Stages Power meter is built onto a Shimano Dura-Ace R9100 crankset. The Stages Power meter is placed on both the drive and non-drive side of the crank in order to independently measure a rider's left and right legs. Tour Proven. 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. Active Temperature Compensation 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 no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions. Individual meter calibration for the most accurate results. Stages Power meters are calibrated individually to ensure a +/- 1.5% accuracy level.
