Reliable chain retention with the DEORE XT Chainring for trail-tuned drivetrains
What Our Gearhead® Experts Are Saying:
"I’ve run the SM-CR86 in both 28T and 32T setups depending on the rear cassette, and I never worry about the chain dropping—even when the trail gets rowdy. It’s lightweight, stiff, and integrates flawlessly with my XT crankset."
We need a chainring that can match our pace and our terrain, and the Shimano DEORE XT SM-CR86 delivers just that. Built for trail riders who demand dependable performance, this direct-mount chainring features Dynamic Chain Engagement technology to maintain a confident connection through rocky climbs and fast descents.
Offered in 28T through 36T options in 2-tooth increments, it adapts easily to a wide range of gearing preferences—whether we’re running a compact drivetrain for tech-heavy trails or a full-range setup for big-mountain days. Reinforced for impact resistance and fully compatible with DEORE XT crankarms, this ring lets us dial in our drivetrain without compromise.
