SRM Shimano XTR MTB Power Meter

If you are looking for the ultimate power meter for your Shimano MTB crankset, look no further! 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 32-38T.

    • Magnet-less cadence
    • Left/Right Power Balance
    • Automatic temperature compensation
    • Bluetooth SMART
  • PM7 – Standard power meter spider version. You save $300 with this version.

SRM PC8 Bundle:

  • SRM PC8 Bundle: You get $249 off the standard price of the PC8 when you bundle it with a SRM power meter.

Chainrings:

  • Please note – if you also need a chainring, we have several MTB chainrings to choose from. Please make sure you select a 104 BCD 4-bolt chainring, size 32T or larger.

Compatibility

Crankset: The SRM Power Meter for Shimano is compatible with Shimano XTR M9100/M9120/M9130 cranks. It is also compatible with all other Shimano x100/x120/x130 series MTB cranksets. This includes the XT M8100/M8120/M8130 or the SLX M7100/7120/7130. It is not compatible with x000 series cranks such as the XTR M9000, XT M8000 or SLX M7000.

Bottom Bracket: This power meter uses a 24 mm Shimano MTB spindle and must be used with a 24 mm Shimano bottom bracket.

Tip - If you already have a Shimano MTB crankset on your bike, then this power meter will fit your bottom bracket perfectly as all Shimano cranksets use a 24 mm spindle.
