Shimano RD-M8100 XT 12-Speed SGS Rear Derailleur

Shimano RD-M8100 XT 12-Speed SGS Rear Derailleur Shimano’s RD-M8100 XT SGS Rear Derailleur is intended for use with 12-speed, 1x drivetrains. The low profile Shadow Plus design and switchable clutch mechanism reduce the chances of the derailleur hitting the chainstay on rough terrain, and make shifting light, easy and precise. A rubber bumper and tension spring keep the drivetrain quiet and smooth, with the direct cable routing preventing any snagging on vegetation on narrow trails. The pulleys have 13 teeth with bearings to keep friction low and the link pin bushings are fluorine coated for increased smoothness and to make shifting lighter. Suitable for use with 51 tooth cassettes, the derailleur can cope with a 41 tooth difference, so is suitable for most wide range, 12-speed cassettes.
