Stages Dura-Ace 9100 Power Meter 170Mm

The new single-sided Stages Power L meter is built on to a non-drive-side Shimano Dura-Ace 9100 crank arm and is compatible with all Shimano Hollowtech II road drivetrains.

Blemished power meter models may have very small blemishes during production. Apart from that the power meter and the crank arm are 100% new.

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
Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters.
