Shimano SM-CRM81 Chainring 1x
Shimano SM-CRM81 Chainring 1x Info
The Shimano SM-CRM81 Chainring 1x is built specifically for Shimano's XT-level single-chainring drivetrain system, designed to work in precise harmony with Shimano's 12-speed MTB groupsets. Its Hyperglide+ tooth profile is engineered for smooth, reliable shifting under load — the kind of shifting that holds up on technical climbs and rough descents alike.
The narrow-wide tooth profile helps retain the chain without a dedicated chain guide, reducing drivetrain noise and keeping things tidy when the trail gets rowdy. Available in 30t and 32t, it covers a practical range of trail and enduro riding demands — the 30t suited to steeper, more technical terrain, and the 32t offering a touch more top-end speed for flow trails and mixed-gradient riding.
