Change Shimano XTR 9100 1x12V / 11V SHADOW + GS short box

The Shimano XTR 9100 change keeps many of the features of its XTR line partners intact. Designed to withstand maximum intensity pedaling on the most abrupt routes, the brand guarantees smooth development changes as it has always been able to provide. Thanks to the original Shadow RD + technology for MTB with a much less oversized core and a structure that accompanies the cassette at all times, it allows to admit large crowns of 34 teeth, while stabilizing and reducing the fall of the chain. This increases its compatibility with the new bicycle frames on the market and disc brakes. It is fully optimized for the new drive system with the controls of the same line with 2-Way Release, Instant Release and Multi Release technologies.
