Stages Powermeter Left arm Shimano 105 R7000 black (1R7L)-172.5MM

Stages Cycling has been in the cycling technology business for over ten years, with dozens of our employees bringing vast industry expertise to launch and drive the company. Stages is the global leader in commercial indoor bike and power meter production. Stages Power meters are all hand-crafted by our beloved production team in Boulder, Colorado, USA, working alongside Stages engineers, whose number one initiative is to propel innovation.

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 worlds best product proving ground, then Stages Power is proven as the worlds best power meter. Stages Power L (left-sided only) is built on to a non-drive side Shimano 105 R7000 crank arm and is compatible with all frames that fit Shimano Hollowtech II cranks. 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. 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 for the dual-sided option means that you can trust the data produced by our system, as it's a real measurement and not an estimation.
