The Shimano XTR SM-CRM95 is a race-grade 1x direct mount chainring engineered for XTR M9100-series cranks. At 36 teeth it suits cross-country, trail, and all-mountain riders who want fast climbing without sacrificing top-end speed — delivered with the chain retention and shift precision XTR is renowned for.

Highlights

• Dynamic Chain Engagement+: Purpose-engineered tooth profile meshes with Hyperglide+ chain links for exceptional engagement and near-zero chain drop over rough terrain.
• Direct Mount interface: Shimano's proprietary direct mount system bolts the ring straight to the crank spider, reducing weight and stiffening the drivetrain compared with traditional BCD rings.
• Aluminium construction: Lightweight alloy body keeps rotating mass low where it counts most on a race-day crankset.
• 1x-optimised tooth geometry: Narrow-wide alternating tooth design locks the chain in place through rock gardens, root sections, and high-cadence efforts alike.
• XTR M9100 series integration: Engineered and tested as a complete system with FC-M9100 and FC-M9120 cranks for smooth, consistent power transfer lap after lap.

Dynamic Chain Engagement+

Shimano's Dynamic Chain Engagement+ technology uses a specially profiled tooth shape that is tuned specifically for the XTR CN-M9100 Hyperglide+ chain. Each tooth is shaped to guide the chain smoothly onto the ring even under load, reducing vibration and dramatically improving chain retention without the need for a chain guide in most trail conditions. The result is a quieter, more confident drivetrain that lets you focus on the ride, not the noise.

Compatibility & Fit

The SM-CRM95 36T is a 12-speed chainring using Shimano's Direct Mount interface. It is compatible with the Shimano XTR FC-M9100-1 and FC-M9120-1 cranksets (and FC-M9130-1). Chainline is 52 mm, suiting standard MTB hub spacing (135/142 mm) and Boost hub spacing (141/148 mm). Requires a Shimano Hyperglide+ (HG+) compatible chain — the SM-CRM95 is not designed for use with standard HG chains. Available in 30T, 32T, 34T, 36T, and 38T to suit a wide range of terrain and gearing preferences.
