The SRM Shimano XTR MTB Power Meter brings SRM’s world–renowned power measurement technology to your Shimano crank. Completely sealed from the elements, the SRM MTB Power Meter can be used in the nastiest, muddiest conditions without fail. The power meter is accurate to 1.0%, features a rechargeable battery and is available in a 104 BCD spider design for rings ranging from 32-36T.
