Shimano XTR M9000 Shadow+ 11 Speed Rear Derailleur

With a refined Shadow RD Plus clutch rear derailleur, a new front derailleur structure and a new XTR chain (CN-HG900-11), M9000 offers the most stable drivetrain the industry has ever seen.

A new Shadow design optimizes the slant angle, lowering shift effort while improving shifting and driving stability while the derailleur is even lower profile protected further from harm’s way. The new Shadow Plus clutch has a simpler external clutch adjustment, and the derailleur has a wider range of adjustment for easier setup.
