Stages Cycling Power Meter L Ultegra R8100

Featuring a Shimano Ultegra R8100 crankarm (left arm only) and a Stages Cycling (non-drive side left) power meter, this model is developed to give you world-class training on your road bike. Compatible with all frames that fit Shimano Hollowtech II cranks, this model offers +/- 1,5% accuracy in all conditions, so you can enjoy precise data measurement. It is also both ANT+ and Bluetooth Smart ready for seamless integration with your wireless smart device, making it easy to run Stages Link, Training Peaks, Strava, Garmin Training Center and others. Powered by a high-quality CR2032 coin cell battery, it provides up to 200+ hours of battery life and comes with a range of ride-enhancing technologies, so you can get the most out of every training session. Whether you’re training for an event or trying to beat your own personal best, this power meter is engineered for performance.

Tour Proven

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 world’s best product proving ground, then Stages Power is proven as the world’s best power meter.

Active Temperature Compensation as Standard Equipment

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. Active Temperature Compensation (ATC) is the key reason a rider can trust data from Stages Power in all conditions.

Individual Meter Calibration for the Most Accurate Results

Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is the industry best for non-scientific power meters. Individual calibration means that you can trust the data produced by the Stages Cycling system, as it’s a real measurement and not an estimation.
