Shimano Deore FC-M6120 12-Speed Chainset FCM6120C2

Shimano Deore FC-M6120 12-Speed Chainset The Deore FC-M6120 12-Speed Chainset offers high value and utilises Shimano’s vast knowledge to grant performance to any mountain bike that encounters even the trickiest and roughest terrain. Forged crank arms donate excellent rigidity to provide efficient power transfer on the most demanding trails. The driveside crank arm is joined seamlessly to the oversized, HollowTech II axle to create a single form that is both strong and lightweight. The oversized axle uses a 24mm diameter that allows the use of wider spaced and larger bottom bracket bearings (available separately) that are more durable and robust. A strong chainring is attached via a sturdy direct mount format and provides a 55mm chainline when used with frames that have a 148mm O.L.D. Compatible with 12-speed HG chains this chainring provides silent running even through mucky conditions. Includes Driveside crank arm and axle assembly Chainring (already installed onto the driveside crank arm) Non-driveside crank arm Bearing preload cap
