The XTR FC-M9100-1 is Shimano's flagship 12-speed 1x crankset: hollow-forged HOLLOWTECH II arms that are as light as they are stiff, built for cross-country and marathon racing. It comes without a chainring so you choose the size — fit an SM-CRM95 direct mount ring from 30 to 38 teeth.

Highlights

  • Hollow-forged arms — HOLLOWTECH II gives race-level stiffness at minimum weight
  • Three lengths — 165, 170 or 175 mm to suit your fit and your frame's clearance
  • Choose your ring — direct mount takes the SM-CRM95 in 30, 32, 34, 36 or 38T
  • Genuine XTR — the crankset the XTR M9100 groupset is built around

What you need with it

An SM-CRM95 direct mount chainring and a Shimano HOLLOWTECH II bottom bracket for your frame shell (threaded BB-MT801 or press-fit BB-MT800 / SM-BB94-41A). Use a Shimano 12-speed chain.
