The XTR M9100 XC 1x12 groupset by Shimano - more efficient than ever

The Shimano XTR XC M9100 1x12 groupset makes no compromises in Cross Country competition, because in terms of shifting efficiency, intuitive and smooth handling and controllable drive behaviour it is the best thing Shimano has brought to the MTB market to date. The 12-speed compatibility is of course the most striking progress. The groupset includes a light, stiff crank with an easily replaceable Direct Mount chainring (34 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.
