Deore 12 FC-M6120 Crankset

Shimano's 12speed system comes to their Deore level with the FC-M6120 crankset. This version is compatible with boost, 148mm rear spaced, frames, for easier upgrading to your current bike. This 1x crankset uses the same dynamic chain engagement technology of their pricier cranksets, in an affordable package. The two-piece design adds rigidity and therefore efficiency to your pedaling, while the direct-mount chainring makes future swaps simple.
  • Shimano's new 12speed crankset for 1x12 systems

What do you think about this product?



Will this work on English Threaded BB 1.37x24t 68-73mm ?


What’s the spindle diameter? Bottom bracket for Soma wolverine?

24mm spindle diameter. BB-MT500-PA is the recommended press fit bottom bracket as per Shimano.


I'm currently running a Shimano Tourney, 42/34/24T, will this Deore crank work on my bike?

Hi Alan, This crankset is a mountain bike crankset for 1x12 drivetrains. In order to use it with your bike, you would need a new bottom bracket. If you are running an 8-speed drivetrain, you would also need to upgrade your drivetrain to at least 11 speed. Or you could look for an 8spd replacement crankset.
