Bringing their expertise to the off-road market, the Stages Cycling XT M8100/8120 L MTB Crank Arm Power Meter has all the same benefits as their road based power meters. The unit itself adds just 15 grams to the base crank arm, and can measure power output up to 2,500 watts with +/- 1.5% accuracy. It has IPX7 water resistance to cope with use off-road in all conditions and automatic temperature compensation for maximum accuracy in rapidly changing conditions. Battery replacement is a tool-free operation and the firmware can be upgraded wirelessly.

Is my bike compatible with Stages Power Meters?

To help find your current crank model, check the inside of the crank arm for the model and length. The next step is to check the power meter's compatibility with your frame; if the space between your crank arm and seat stay fits a 10mm Allen key wrench between 5cm and 12cm from the centre of your bottom bracket, this should be compatible.

Still unsure? See this illustration for a guide of where to measure.
