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: 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 Cervelos 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. - 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 means that you can trust the bi-lateral data produced by our system, as its a real measurement and not an estimation.
