Proven tour
Stages Power has led riders to three consecutive Tour de France victories, in addition to many more world and national championships. If you think racing offers the best product testing ground in the world, Stages Power is proven to be the best power meter in the world.
Active temperature compensation as standard equipment
Consistency of measurement is the most important characteristic of a power meter. Stages Power was the first meter to turn temperature compensation into an automatic process that ensures accurate readings regardless of environmental conditions. ATC is the key reason a rider can rely on Stages Power data in all conditions.
Individual meter calibration for the most accurate results
Each Stages power meter is individually calibrated to ensure an accuracy level of +/- 1.5%, which is the best in the industry for non-scientific power meters. Individual calibration for the double-sided option means that you can trust the data produced by our system as it is an actual measurement and not an estimate.
Stages Power R drive-side meter for added compatibility or upgrade an existing Stages Power L meter to Stages Power LR
While not widespread, there are some key bike models that are not compatible with the Stages power meter based on non-drive cranks due to interference with the power meter housing, for example the Cervelo P5 and many bikes with chainstay mounted brake calipers. 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.
