SRM Takes Mountain Bike Power Meter Cranks Single File for 1x Drivetrains (UPDATED)
The new SRM 1x PowerMeters bring an updated design to their off road crankset power meters, and it’s way cleaner than the prototypes we spotted at Sea Otter last year!
The unit is completely sealed from the elements and uses a smooth, flat external housing to keep mud and debris from sticking to it. Inside, their solid state battery is good for up to 700 hours of riding. It’ll be upgradeable to their externally (i.e. user) rechargeable battery when it becomes available later this year.
The 1x SRM uses a standard 104BCD spider to accommodate standard size chainrings, and they claim it adds just 70g to the crankset. It’s available on SRAM XX1, Cannondale SiSL2, FSA K-Force Light and Shimano XT cranksets, and you can choose between SRAM XO1 X-Sync rings (32t-38t) or Race Face Narrow-Wide Single-Rings (30t-38t).
They communicate wirelessly via ANT+ to the SRM Power Control 7 or any other ANT+ cycling computer that’ll read power data.
