Popular Shimano XTR M9100 XC 1×12 32 Groupset

The XTR M9100 XC 1×12 groupset by Shimano – speed, focus control

The XTR XC M9100 1×12 groupset was uncompromisingly designed by Shimano for use in Cross Country competition. Increasing shifting efficiency, ensuring intuitive and smooth operation and creating predictable drive behaviour – these were the objectives, with 12-speed compatibility naturally representing the most striking progress. The groupset includes a light, stiff crank with an easily replaceable Direct Mount chainring (32 teeth), which, together with the Quick-Link chain, ensures smooth forward motion and even pedalling. Also included are a Shadow Plus rear derailleur and a cassette with innovative Hyperglide+ Micro Spline construction. On the cockpit side, Shimano surprises with a shifter (right) in an I-Spec EV design, which offers even more adjustment possibilities and thus more flexibility.
