4iiii PRECISION Shimano XTR M9100 Power Meter

The 4iiii PRECISION Shimano XTR M9100 Power Meter is brings power to your M9100 or M9120 crankset. The 4iiii PRECISION power meter is a left-only crank arm-based power meter and replaces your current left side crank arm. It takes the power that is generated by your left leg and doubles it in order to determine your total power output.

Using 3D power meter technology capable of measuring tri-axial strain, the 4iiii XTR M9100 Power Meter is accurate to +/- 1.0%. In addition, it’s very lightweight, adding only 9 grams of weight to your crankset.

It features 100 hours of battery life and is compatible with both ANT+ and Bluetooth SMART devices. This means it’s compatible with your favorite bike computer, smart phone or tablet.
