Shimano's innovative Shadow RD + 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 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 with taller tooth pully wheels that greatly lightens up the shift operation, allowing up to 20% less effort.
