Stages Power L - Shimano Ultegra R8100 Gen3

The Stages Power L Shimano Ultegra R8100 power meter is a single-sided powermeter for cranks of the Shimano R8100 series. It measures the power on the left crank arm. The Stages power meter is now available in the 3rd generation. It is positioned discretely on the inner side of the left crank arm, weighing in at a mere 15g.

It's accurate (±1.5%) and easy to install. Stages L power meters always come mounted to the left crank arm. So all you have to do is find the model, which is compatible with your existing crank set and simply swap the left crank arm.

For Ultegra R8100 riders Stages offers a power meter as a replacement non-drive crank arm for existing Ultegra model cranks. Riders looking to add power to their existing crank need only select length, as the Stages Power meter for Ultegra fits all styles of Shimano road crankset, including: compact and standard.

The special thing about Shimano: the Stages Shimano Ultegra R8100 Powermeter fits not only to cranks of the same series, but to all Hollowtech II road cranks (eg Ultegra R8000 or 105 R7000).

Frame compatibility

Since the power meter is placed on the inside of the crank arm, a clearance of at least 10mm between crank and chain stay / direct-mount brake is needed. Especially bikes with direct-mount brakes may cause problems.

To ensure your bike is compatible with the Stages Power Meter, please perform a simple check with a 10mm hex key:
