Stages Shimano XT M8100/8120 Power Meter

The Stages Shimano XT M8100/8120 Power Meter brings Stages power to your MTB bike! Compatible with the XT M8100/8120/8130 cranksets, the Stages power meter is accurate, durable and ready to handle the toughest terrain. Simply remove your current left-side crank arm and replace it with the Stages power meter and you’re done!

The power meter is extremely lightweight – adding only 15 grams to the weight of the crank arm. All Stages power meters are compatible with both ANT+ and Bluetooth SMART devices, which means you can use your favorite bicycle computer as well as a smartphone or tablet.

The Stages Generation 3 power meter features radio antennas that are 6x more powerful than the previous version. This means better compatibility with both bike computers and watches. The new versions also feature improved accuracy (+/- 1.5%) and have an LED indicator light on the housing for improved ease of use.



Crank arm lengths: 165 mm | 170 mm | 175 mm



The Stages power meter is compatible with XT M8100/8120/8130 cranksets. It is also compatible with all other Shimano x100/x120/x130 series MTB cranksets such as the XTR M9100/M9120/M9130 or the SLX M7100/7120/7130.

    Cheap and reliable. Always agrees with my left side garmin vector 3; and paired with my drive side stages power meter, gives me perfectly consistent numbers, compared with my trainer. It’s a 9.5 out of 10, just because is left only.
