Stages R8000 R Dx power meter

The Stages LR power meter is pre-assembled on both the left crank and the driver's side of aShimano Ultegra R8000 crankset, measures the performance of the left and right legs independently of each other and impresses with its basso additional weight of only 35 grams.

With a measuring accuracy of +/-1.5 %, an integrated acceleration sensor for cadence measurement and active temperature compensation as a standard function, the power meter also convinces Stages with its ease of use. Especially for Shimano models you can choose between single-sided or two-sided power measurement. Via Bluetooth Smart and ANT+ pairing with all common bicycle computers (Stages, Garmin, Polar, Sigma, Suunto, Wahoo, etc.) or smartphones takes place in a few seconds.

Tested in the race
Power meters Stages have accompanied athletes on their way to three consecutive Tour de France victories and many national and world titles. If you see running as the toughest test bed for the best products, Stages have proven to be the best power meters.

Active temperature compensation as standard function
Providing consistent performance data is the most important function of a power meter. Stages meters were the first to implement temperature compensation as an automated process, ensuring accurate measurements in all environmental conditions. ATC is the key factor for precise performance measurement and the reason why athletes can always rely on Stages meters.

Independent calibration for maximum accuracy
Each meter in the Stages is individually calibrated. This ensures measurement accuracy of +/-1.5% and is the best in the industry for non-scientific power measurement systems. Individual calibration means that the output power data of both sides are actual measured values and not estimated values.
