SHIMANO XTR RD-M986 Rear derailleur

The new 10-speed XTR Shadow PLUS rear derailleur sees a re-engineered architecture that provides a smooth, linear feel at the shifter and is remarkably stable despite suspension movement, trail chatter or inevitable cable contamination. The internal clutch system maintains chain tension through the roughest of terrain, fully adjustable with included tool and built in on/off switch round out the Shadow Plus RD.
