The Shimano XTR SM-CRM95 is a race-grade direct mount chainring built for XTR 12-speed 1x drivetrains. Designed to pair with the FC-M9100 and FC-M9120 cranksets, it delivers confident chain retention and smooth power transfer on demanding cross-country, trail, and enduro terrain — exactly where XTR is designed to perform.

Highlights

  • Dynamic Chain Engagement+: Shimano's advanced tooth profile keeps the chain engaged through rough, high-vibration terrain, dramatically reducing the chance of chain drop without a guide.
  • Narrow-wide tooth profile: Alternating narrow and wide teeth mesh precisely with 12-speed Hyperglide+ chain links for positive retention across all conditions.
  • Direct mount interface: Shimano's 4-arm direct mount system eliminates the traditional spider, reducing weight and simplifying chainring swaps.
  • Aluminium construction: Lightweight alloy provides an excellent strength-to-weight ratio for race and performance trail riding.
  • 30T for climbers and technical terrain: A smaller ring choice that maintains cadence and control on steep, technical climbs.

Designed for XTR Performance

The SM-CRM95 is the dedicated chainring for Shimano's top-tier XTR M9100 groupset. The geometry and tooth shaping work in harmony with XTR's 12-speed cassettes and the CN-M9100 chain to deliver precise, low-friction shifting and engagement. Whether you're pushing the pace on an XC course or navigating technical singletrack, the SM-CRM95 keeps power delivery clean and consistent.
