Can I install a Shimano R8100 power meter on a Shimano 8000 or 6800 crankset?

Yes, you can install a Shimano R8100 power meter on a Shimano 8000 or 6800 crankset as they both use the same interface – which is called Shimano Hollowtech II.

Stages Shimano Ultegra R8100 Power Meter

Please note, the color of the crank arms won’t be exactly the same (a cosmetic issue only), but they are very close so most customers are ok with this.

Please note, these power meters attach a sensor to the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 10 mm of clearance for Stages power meters. Also, please make sure that you don’t have a bottom bracket mounted rear brake (used on some aero and TT bikes). Please refer to the image below.
