Shadow+: stabilizes chain movement in difficult terrain to eliminate dropped chains
Carbon outer cage plate
Sealed bearing pulleys
Imagine never dropping your chain again. Now imagine that you are riding a triple and have full shifting capabilities! The Shimano XTR M986 Shadow Plus Rear Derailleur is a revolution in rear derailleur design, allowing the cage to swing backward, but limiting forward motion. The result is a chain that stays in tension, never slapping the stays. The XTR M986 Shadow+ derailleur is a chain guide and rear derailleur all in one.
The XTR M986 Shadow Plus derailleur uses premium materials as well as Shimano's Shadow derailleur design that tucks the rear Derailleur further into the frame decreasing the likely hood of of it snagging on a tree branch or other obstacle. The XTR M985 Shadow Plus rear derailleur is compatible with both 2x10 and 3x10 systems.
