Mountain biking has rapidly evolved since the previous introduction of Shimano’s top level XTR groupset. Shimano sees different directions in mountain biking with wheel sizes and riding styles changing and now defines four main categories within mountain biking. Competitive Cross Country is driven by physical efforts while Enduro focuses on more technical challenges but both have equivalents at the non-competitive Trail level. To serve mountain bikers who will only settle for the best, Shimano today introduces the new rider tuned XTR M9000 groupset. 

New XTR M9000 provides range and ensures rhythm for diverse riding styles and terrain to create smooth, harmonic pedaling - the ultimate goal of a drivetrain. 

Crankset FC-M9000-1 for 1x11-speed 

The 1x11 drivetrain is the best option if you are a competitive Cross Country or Enduro racer and you know exactly your skills and the level of terrain you are going to face. 

The FC-M9000 is a race specific crank arm with a cold forged super strong construction and a 158mm Q-factor. It comes without chainrings. But it is no problem to realize 1x, 2x or 3x setups with the corresponding chainrings. 

The XTR 1x chainring is optional available and features retention technology with a unique tooth profile that eliminates the need for chain retention devices. 

Optional chainrings: 

• 30 teeth
• 32 teeth
• 34 teeth
• 36 teeth

Only compatible with HG-X11-speed chains.
