Shimano RD-M986 Rear Derailleur

The newest incarnation of the XTR rear derailleur features Shimano’s new direct mount option that positions the rear derailleur in a way that protects it from hitting rocks or other obstacles, creates a stiffer shifting platform, and makes rear wheel changes faster and easier. It also comes equipped with Shadow Plus clutch technology that effectively eliminates chain slap and reduces the chances of dropping your chain. With these new upgrades, the XTR group continues to push the standard for top of the line mountain components trusted by pros and every day riders alike.

  • Dyna-Sys Technology, for 10 speed drivetrains only
  • Compatible with standard dropouts and new Direct Mount dropouts
  • Shadow Plus Clutch technology
  • Carbon fiber outer plate

      Switched both bikes to xtr 10 speed and I am very satisfied with all of the Dynasys components. Don't scrimp on your drive train if possible.

          This is the second XTR derailleur I have owned. They perform flawlessly and I have never dropped a chain. Smooth and crisp shifting.

            Just had this derailleur installed about a month ago & so far so good. I have yet to have the chain fall off & the chain slap is virtually non existent. I hope it stays that way for the life of the derailleur.

            XTR does not get any better. Great fast shifting. Shadow plus works great with 1*10 drivetrain.

              Comments about Shimano XTR M986 Rear Derailleur:

              I built a Yeti SB66 from the frame up. Coming from a 5 year old XT RD is like night and day. Ultra low profile tucks neatly under the rear cassette out of the way. Fit and finish is great, as with anything XTR. I got this for a great deal as an OE take off part. No packaging included, but in perfect condition. Unless you just have to have the factory manual, this is a great option to buy.
