Power Meter G3 R with Chainrings - Shimano Dura-Ace R9100

The new Gen 3 single-sided Stages Power R meter is built on to a driveside Shimano Dura-Ace R9100 crank arm and is compatible with all frames that fit Shimano Hollowtech II cranks.

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.

Single drive-side power meter increases frame compatibility or upgrades an existing Stages Power L meter to Stages Power LR.  Stages Power R offers increased compatibility with direct mount brakes and frames that lack adequate chainstay clearance, as well as the ability to upgrade existing Stages Power L power meters to Stages Power LR bi-lateral (dual) meter systems.
