Shimano XT Rear Derailleur M8000 SGS 11 Speed


Brand Shimano

The long-awaited Shimano XT 11 speed drivetrain has made its grand entrance! Featuring Shimano’s innovative Shadow Plus technology and a refined geometry, the Deore XT M8000 11-speed rear derailleur is designed to reign authority over today’s aggressive style of trail and all-mountain riding. By maintaining chain tension, the optimized slant angled Shadow system eliminates chain slap and greatly lowers the chances of dropping your chain. The easy-to-adjust chain stabilizer makes it quick and effortless to dial in the perfect amount of stability for varying conditions and terrain.

The XT M8000 rear derailleur employs a new hyper low-friction coating technology and an improved pulley design that greatly lightens up the shift operation, allowing up to 20% less effort. Finally, support for larger rear clusters is offered as well, with clearance on up to 11-46T rear cassettes for massive range.

Don't know which cage length to choose? Choose a long cage "SGS" derailleur if you have 3 chainrings on your crankset, and a medium cage "GS" if you have 1 or 2 front chainrings.
