Shimano XTR Shadow Plus Rear Derailleur (Long Cage)

From top-tier XC racing to punishing endurance stages, Shimano defines the rear derailleur with their XTR Shadow Plus 11-speed model.

Shimano's Plus derailleur technology is a one-way clutch system that stabilizes the cage and your chain when ripping over rough terrain. Chain slap and noise is virtually eliminated and dropped chains are practically a thing of the past. And of course, it retains XTR's legendary smoothness, light action and super precise shifting.
