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.
  • For 10 spd drivetrains
  • Compatible with standard dropouts and new Direct Mount dropouts
  • Shadow Plus Clutch technology
  • Carbon fiber outer plate

    Comments about Shimano XTR M986 Rear Derailleur:

    I did a complete upgrade of my drivetrain and this was a major part. Wow, I'm running this with a XT 3x crank, XT cassette, KMC Gold 10SL chain and XT trail pedals with XT B-spec. shifters on a 2013 Giant XTC. This derailleur in conjunction with these parts is beautiful! Effortless shifting and shift on the fly performance. Would highly recommend the XTR shadow plus set-up. No more chain slap, keeps everything right where it should be...on the bike!
    I would say next to buying a good set of wheels, this would be a must for the next upgrade on your bike.
    Thanks to Jenson for there unbelievable service, prices and honesty, You guy's rock, keep up the outstanding work!

    XTR rear derailer review

    Pros

    • Durable
    • Easy To Install
    • Lightweight
    • Smooth shifting

    Cons

    • Limited Compatibility

    Best Uses

    • Mountain Biking

    Comments about Shimano XTR M986 Rear Derailleur:

    Put this derailer on a 1x10 conversion on my bike and my daughters. Added a 42 tooth rear chain ring and a custom b screw cassette clearance adjustment. The derailer works great on my Orbea ALma 29er but has an issue on my daughter's Scott hardtail in one high gear. Not enough of an issue to force a change back. Not the derailers fault as they weren't made for huge rear chain rings. The only complaint I have is the resistance to shifting in a few gears due to, I assume, the clutch. Otherwise works great at eliminating chain slap. I am happy.

      This derailleur has been great! I have not noticed much with the clutch system, but then again, I live in Illinois so probably not much of a proving ground!

        I installed this on my 9 speed xt drive train even though it is a 10spd derailleur. I had to use a 9 speed SRAM shifter that has the same 1:1 ratio as a 10 SPD shimano. Works almost perfect. The clutch is great I have not dropped a chain since switching. No more chain slapping either. I have noticed the chain loosened a bit after a few months, but the clutch has adjustment capability.

          Comments about Shimano XTR M986 Rear Derailleur:

          As with almost everything XTR - it is not a need.
          If I had a bike outfitted with XT, I would not be motivated to upgrade. In this instance, the entire drive train was being replaced and the difference in price between the XT & XTR was not significant due to a sale. It works as advertised and looks great. The new clutch system seems to be working quite nicely.

            Swap my XT rear derailleur for this XTR. I'm very happy I did. Gear change is as smooth and reliable as you'd expect from an XTR product. You pay more but you get more.

                The Shadow Plus clutch worked perfectly with my XX1 conversion. Raced and all-around trained with no chain throw issues, no chain guard needed on my XX1 cranks and chainring. Absolutely recommend this for 1x10 if not going for 1x11.
