INPEAK POWERCRANK Shimano XT M8100 Power Meter

INPEAK POWERCRANK Shimano XT M8100 Power Meter

The INPEAK POWERCRANK Shimano XT M8100 Power Meter is the perfect upgrade for riders with Shimano XT M8100 cranksets. This INPEAK power meter replaces your current left-side crank arm. It measures the power generated by your left leg and doubles it to determine your total watts. Data transmits via ANT+ or Bluetooth Smart, ensuring seamless connectivity with your preferred head unit or training app.

Designed in Poland, INPEAK made the POWERCRANK sensor to handle whatever the Polish climate threw their way. As a result, the INPEAK M8100 power meter is IP67-rated for water and dust resistance. Alongside water and dust protection, it features active temperature compensation from 23°F to 122°F. While the INPEAK can withstand any adventure, it is also one of the lightest options available and adds only 10 grams to the crank arm. Rain or shine the INPEAK Shimano M8100 Power Meter will dutifully record your stats ride after ride.

Product Details

Key Features of the INPEAK POWERCRANK M8100 Power Meter

• Robust Durability: The IP67 water and dust sealing and wide operating temp range means training in the snow or desert is not off the cards.
• Compact Design: Only 7.5 mm thick and 10 grams means the sensor fits most frames and adds minimal weight.

• Data Multiple Ways: ANT+ and Bluetooth Smart connects to head units such as a Garmin Edge and a variety of training apps such as Zwift.

Power Measurement

This INPEAK power meter measures left leg power and doubles the value to account for both legs (assumes both legs are generating the same force).

Compatibility

This power meter is compatible with Shimano M8100 cranksets. It can also be installed on other Shimano MTB cranksets, as long as they use Shimano’s Hollowtech II spindle interface. See Compatibility tab for more information.

Considerations

The INPEAK POWERCRANK M8100 Power Meter measures power only from your left leg. This means total power is estimated by doubling the left leg’s output. While this works well for many riders it may be less accurate if there is a strength difference between your legs. This is common with single-sided power meters and worth considering if precise total power is your priority. In addition, the +/- 2.0% measurement accuracy is less than other options, although for many riders this is only a few watts in either direction.

Advice From Our Staff

We believe this power meter is great for riders who want reliable power data without buying a full crankset. We feel it is a great upgrade if you already have a XT M8100 crankset as it is easy to install, offers good power data in a durable and affordable package.
