The Shimano XT SM-CRM86 chainrings are purpose-built for aggressive trail and enduro riding, offering reliable chain retention and impact resistance in a lightweight, direct-mount design. Engineered with Shimano’s proven Dynamic Chain Engagement technology, these chainrings deliver consistent chain retention by improving tooth profile engagement, minimizing drops even on rough terrain. Compatible with DEORE XT cranksets, the SM-CR86 is available in sizes ranging from 28T to 36T in two-tooth increments, allowing riders to fine-tune their drivetrain for optimal cadence and terrain coverage. The compact 28T option is ideal when paired with a mid-cage rear derailleur and a 9-45T cassette, creating a lightweight setup that maintains wide-range gearing without the added bulk of a traditional drivetrain. Reinforced for durability and designed for modern 1x drivetrains, the SM-CR86 chainring ensures high-performance efficiency and durability for demanding mountain bike conditions.
