Shimano Deore XT is the original mountain bike groupset trusted by generations of mountain bikers around the world. Whatever the trail, whatever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high-performance workhorse you can count on.
The Shimano M8100 2x12 groupset is the first XT with 12-speed compatibility - a step that the XTR has taken before and that now allows even more bikers to use it. It consists of a two chainring crank (26 & 36 teeth) with 3 mm further out chain-line, front derailleur, rear derailleur, two shifters, Quick-Link chain and cassette with a 10-45 or 10-51 gradation. M8100 is the first 2x12 XT groupset - a step first taken by XTR, now accessible to a wider audience. As with the original XT, the focus is on endurance and performance, coupled with the riding pleasure and adventure that modern mountain bikers seek on the trails. Leave your mark - with the XT M8100 by Shimano.
