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.

Individual meter calibration for the most accurate results. Stages Power meters are calibrated individually to ensure a +/- 1.5% accuracy level, which is an industry best for non-scientific power meters. Individual calibration means that you can trust the data produced by our system.

Accelerometer based cadence measurement
Wirelessly upgradable firmware
LED indicator displays battery level at start up (with no need for connect to an app) and confirms successful zero reset
