SRM SRAM XX1 MTB Power Meter

The SRM SRAM XX1 MTB Power Meter combines world–renowned SRM power measurement technology with SRAM’s best in class XX1 drivetrain. Completely sealed from the elements, the 1X MTB SRM 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.



Crank Arms:

  • 165 mm | 170 mm | 175 mm

Chainline Spacing:

  • Standard (48-50 mm) | Boost (51-53 mm)

SRM PC8 Bundle:

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


  • 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.



This SRM power meter uses the SRAM Durable Unified Bottom Bracket (DUB). DUB bottom brackets are available in BB30, PF30, BSA (threaded), PF89/92, as well as fat bike standards. Contact us if you have questions on the compatibility for your bike.
