MTB cranks and chainrings

The Shimano XTR FC-M9100 1-speed crank stands for highest drive efficiency at low weight. With her, Shimano has properly advanced the 1-speed evolution. It offers optimum power transmission and maximum speed for the new XTR systems, which only use 1 chainring - and is compatible with the new 11- and 12-speed cassette. It’s lighter. It’s stiffer. It’s smoother. What else would you expect from next gen XTR? Optimal power transfer for maximum speed? Splined interface chainring? Don’t worry, you get it all!Features - XTR FC-M9100-1 11/12-speed Crank FC-M9100-1 Q-Factor 162mm Compatibility 1x11-speed with CS-M9110-11 cassette 10-45 + RD-M9100-GS rear derailleur 1x12-speed with CS-M9100-12 cassettes 10-45 and 10-51 Mounting system Direct mount (Lighter and stiffer design & easy exchangeable chainring by direct mount and one key release) O.L.D 142mm Chainring SM-CRM95 Available in different gradations (30-32-34-36-38) - Chainring is not included!
