Road-tested
Stages power meters have accompanied athletes on their path to three consecutive Tour de France victories and numerous national and world championship titles. If we consider races to be the toughest test bed for the best products, the Stages power meter has proven itself to be the best.
Active temperature compensation as a standard feature
The most important function of a power meter is to provide consistent performance data. The Stages Powermeter was the first power meter to implement temperature compensation as an automated process, ensuring accurate measurements in any environmental conditions. ATC is the key factor for precise power measurement and the reason why athletes can always rely on Stages Power.
Individual calibration for maximum measurement accuracy
Every Stages power meter is individually calibrated. It guarantees a measurement accuracy of +/-1.5% and is the best in the industry for non-scientific power measurement systems. Individual calibration on the Stages Power LR means that the power output data from both sides are actual measured values and not estimated values.
