The Deore XT RD-M8100-SGS rear derailleur provides fast and precise shifting operations over a wide gear range. Guide and tension pulleys with 13 teeth and sealed bearings as well as a rubber damper reduce noise and increase ride comfort. They also improve the chain's grip under all conditions.
The Shimano RD-M8100 is specifically designed to work with 12-speed 1x drivetrains and is suitable for use with both the large 10-51 tooth and the smaller 10-45 tooth Shimano CS-M8100 cassette.
Shimano's new Direct Mount Rear Derailleur system gives more space around the rear frame dropout resulting in easier rear wheel removal but also allows frame designers to shorten chain stays, increase axel sizes and move suspension pivots.
