STAGES CYCLING Power Meter L Shimano | Ultegra R8100

Train like a pro.
Stages power meters have accompanied athletes on their way to three Tour de France victories in a row. You have also been on the bike at many national and world championship titles. If you see racing as the toughest test bench for the best products, the Stages power meter has proven to be one of the best power meters.

The Stages Powermeter L for your Ultegra R8100 crank.
The power meter is pre-assembled on the left crank and, once the correct crank length has been selected, can be exchanged for the existing crank arm extremely quickly and easily.
The advantages compared to other systems: there is no intervention in the tuning of the bike or the gears, you can continue to use your preferred pedals and it is assembled and ready for use in just a few minutes. To always be up to date, you can use the Stages app to update the firmware wirelessly at any time, check the battery charge level or calibrate the power meter.

Thanks to the flat design of the housing, the Powermeter L fits almost any frame. Before final assembly, please check whether there is enough space for the frame and other components. Please refer to the operating instructions.

Active temperature compensation as a standard feature
Providing consistent performance data is the most important function of a power meter. The Stages power meter was the first power meter to implement temperature compensation as an automated process, ensuring accurate readings in any environmental condition. ATC is the central key factor for precise power measurement and the reason why you can always trust Stages Power.

Independent calibration for maximum precision measurement
Each Stages power meter is individually calibrated after assembly. This ensures +/-1.5% measurement accuracy and is the industry best for non-scientific power measurement systems. The system also measures your cadence via the integrated acceleration sensor.
