For sale is a high-performance Shimano XTR M985 rear derailleur, the pinnacle of the 10-speed Dyna-Sys era. This model features the iconic Shadow Plus technology, including the gold-colored clutch switch that provides superior chain tension and eliminates chain slap on rough terrain.

The derailleur is in good working condition with some cosmetic scuffs from normal trail use (as seen in the photos). The cage is straight, and the shifting remains crisp and precise. Perfect for weight-weenie builds, retro-MTB restorations, or anyone looking for pro-level shifting performance.
