Stages Ultegra R8100 L+R Power Meter

Take your workouts to the next level and improve your cycling performance with the Stages Ultegra R8100 Dual-Sided Powermeter. Suitable for the Shimano Hollowtech II Race crankset, this power meter provides accurate and reliable power measurements, giving you insight into your performance and allowing you to optimise your workouts.

Years of experience and innovation
The high-quality third-generation power meters from Stages, a company with years of experience in (professional) cycling, are handmade in the United States. Constant improvements in their power meters and individual calibration ensure optimum accuracy, with only a maximum measurement deviation of 1.5%. The Active Temperature Compensation (ATC) Technology ensures accurate power measurement regardless of environmental and weather conditions. In addition, the optimised internal accelerometer ensures a wireless and precise measurement of your cadence.

Battery life and connectivity
The CR2032 button cell battery offers you about 175 hours of battery life and is easy to replace. On the left crank arm you can even do this without tools, for the right crank arm you only need a Phillips screwdriver. The integrated LED indicator provides you with battery level and calibration information. The ANT+ and Bluetooth connection ensure optimal data transfer and connection to almost all modern bike computers. Finally, IPX7 water resistance means you can train in wet conditions with confidence.

Double-sided or single-sided?
A double-sided power meter is a bit heavier than a single-sided power meter, but will provide you with even more accurate and comprehensive data. The double-sided measurement, as in this Stages Dura-Ace R9200 double-sided power meter, provides information on both legs, making it easy to spot left/right differences, for example. A single-sided power meter simply doubles the single-sided measurement to determine the total power output.
