At Escapa, we know how important the power meter is—discover our selection of the best brands.
The Stages Power R - Shimano Ultegra R8100 - 172.5mm is pre-installed on a Shimano Ultegra R8100 crankset and is compatible with all frames that support Shimano Hollowtech II cranksets.
Active Temperature Compensation (ATC) 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.
Independent calibration for maximum measurement accuracy
Every Stages Powermeter is individually calibrated. It guarantees a measurement accuracy of +/-1.5% and is the best in the industry for non-scientific power measurement systems.
