Stages Cycling Power R Power Meter Guarnitura con 52/36T Chainring per Dura-Ace R9100

The most advanced power meters in the world.
Nearly a decade of relentless development. High-resolution Gen 3 electronics with enhanced signal strength. Certified water resistant to IPX7 standards. Active Temperature Compensation. Magnet-free cadence. ANT+ and Bluetooth transmission. Universally compatible. This is the gold standard for power meters.

The Stages Power meter R for Shimano´s Dura-Ace R9100 crank set is built on to a drive side Shimano Dura-Ace R9100 crank arm and is compatible with all frames that fit Shimano Hollowtech II cranks.

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.

Stages Power R drive-side meter for added compatibility or as an upgrade
While not widespread there are some key bicycle models that are not compatibile with the non-drive crank arm based Stages Power meter because of interference with the power meter housing, for example Cervelo's P5 and many bikes with chainstay mounted brake calipers or Boost-standard. Stages Power R offers increased compatibility with these models as well as the ability to upgrade existing Stages Power L power meters to Stages Power LR (dual) meter systems.
