The SRM SRAM XX1 MTB Power Meter combines world–renowned SRM power measurement technology with SRAM’s best in class XX1 crankset. 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 32-38T.

Compatibility

Crankset: This power meter works with SRAM XX1 Eagle DUB 3-bolt cranksets, which can be purchased on this page along with the power meter.

Chainrings: This power meter requires a 104 BCD 4-bolt chainring MTB chainring, size 32T or larger. If you don't already have a 4-bolt chainring, we offer several different MTB chainrings to choose from. In most cases, we recommend the Quarq SRAM X-SYNC 2 12-Speed Chainrings for best performance.
