The Shimano Deore XT SM-CRM85 is chainring that incorporates modern technologies to meet the needs of the contemporary MTB with a 1×12 setup.

The Direct-Mount construction allows for easy and quick installation on cranksets from the XT series (FC-M8100, FC-M8120, FC-M8130).

The Dynamic Chain Engagement+ (DCE+) technology ensures that each tooth accurately guides the chain, reducing the risk of derailment and providing quiet and smooth operation even on rough terrain.

Combined with a HG 12-speed chain, the transmission delivers power efficiently and smoothly, while the Direct-Mount design reduces unnecessary parts and increases stiffness.

Ideal for XC, Trail, All-Mountain, and generally MTB bikes that use 1×12 drivetrains.
