The XTR M9100 XC 1x12 groupset by Shimano - speed, focus control
The XTR XC M9100 1x12 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.
