Tested or Tour

Stages Power has led riders to three consecutive Tour de France victories and manyautres world and national championships. If you think racing provides the world's best testing ground, then Stages Power is the world's best power meter.

Active Temperature Compensation (ATC) as standard equipment

Consistency of measurement is the most important feature of a power meter. Stages Power was the premier meter to make temperature compensation an automatic process, ensuring accurate readings whatever the environmental conditions. ATC is the main reason why a rider can trust Stages Power's data in all conditions.

Individual meter calibration for more accurate results

Each Stages Power sensor is individually calibrated to guarantee an accuracy level of +/- 1.5%, which is the best accuracy level in the industry for non-scientific sensors. Individual calibration means you can trust the two-sided data produced by our system, because it's an actual measurement, not an estimate.

Stages Power R for enhanced compatibility or upgrading an existing Stages Power L meter to Stages Power LR

Although not widespread, some key bike models are not compatible with the Stages Power L crank due to interference with the power meter housing, e.g. Cervelo's P5 and many bikes fitted with chainstay-mounted or standard Boost brake calipers. Stages Power R offers enhanced compatibility with these models, as well as the possibility of upgrading existing Stages Power L meters to Stages Power LR bilateral (dual) meter systems.
