The SM-CRM85 is the genuine Deore XT direct mount chainring for Shimano's 12-speed FC-M8100, FC-M8120 and FC-M8130 cranks, available from 28 to 36 teeth. Change your gearing or replace a worn ring in minutes: it bolts straight onto the crank's direct-mount spider with no chainring bolts.

Highlights

  • Five sizes — 28T and 30T for steep, technical riding; 32T for all-round trail; 34T and 36T for speed and strong legs
  • Made for the chain — the HYPERGLIDE+ tooth profile is cut for Shimano 12-speed chains and keeps the chain on over rough ground
  • Direct mount — one ring, no spider, no bolts to work loose
  • Genuine XT — the same ring the cranks ship with

Compatibility

Fits the direct mount of Shimano FC-M8100-1, FC-M8120-1 and FC-M8130-1 cranks. Use a Shimano 12-speed chain. Check your frame's chainring clearance before going up in size.
