Stages XT M8100/8120 Left Power Meter

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. Individual calibration for the dual-sided option means that you can trust the data produced by our system, as it's a real measurement and not an estimation.

Stages Power R drive-side meter for added compatibility or upgrading an existing Stages Power L meter to Stages Power LR

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.
