Stages Power meters are ridden by world and national champions in every discipline of cycling. From weekend warriors to Erin Huck, Nate Hills and the Yeti/Fox Shox Factory Race team, Stages Power for MTB is ridden by the best athletes in the world.

Built on a non-drive-side Shimano XTR M9100/M9120 crank arm, the new Gen 3 single-sided Stages Power L meter offers durable and accurate power measurement.

Consistency of measurement is the most important feature of a power meter. To this end, Stages Power was the first meter manufacturer to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions.

Stages Power meters are calibrated individually at the brand's state-of-the-art Boulder, Colorado facility to ensure a +/- 1.5% accuracy level. Individual calibration means that you can trust the data produced by its system.
