Shimano SM-CRM75 Chainring 1x

The Shimano SM-CRM75 Chainring 1x is built for Shimano's XT-level 1x drivetrain systems, giving mountain bikers a dedicated narrow-wide chainring designed to work in lockstep with the rest of the XT group. The alternating tooth profile grips the chain securely across rough terrain, reducing the need for a separate chain guide on most trail setups. Available in 30t, 32t, and 34t options, the SM-CRM75 lets you dial in your gearing for the terrain you actually ride — whether that's steep technical climbing or rolling singletrack where you want a bit more top-end. It's a direct-mount chainring designed for Shimano's direct-mount crankarms, so fitment is clean and chainline is dialed from the start.
