The Shimano SLX FC-M7130-1 is a 1x12 crankset with hollow forged arms and a direct mount chainring. Its 56.5 mm chainline is made for frames with 157 mm rear spacing.

What it's for

A crankset for Shimano 12 speed bikes with 157 mm (Super Boost) rear hubs.

How it works

HOLLOWTECH II: hollow forged crank arms on a 24 mm axle with outboard bearings, for stiffness at low weight.

DYNAMIC CHAIN ENGAGEMENT+: a chainring tooth profile for single ring drivetrains that holds the chain and pedals smoothly.
