    The shadow knows.

    Bringing constant refinement to the 11-speed XT drivetrain, the Shimano XT RD-M8000 Rear Derailleur offers improved chain retention when you're riding across jarring, rock-strewn trails. Benefiting from trickle-down technology from the XTR group, Shadow RD+ technology keeps the chain from bouncing around with its handy stabilizer switch. The Shadow design is optimized for increased stability with its slanted position, allowing for silky-smooth shifting in every gear.

    The XT's robust aluminum construction takes a serious beating without fuss, equating to worry-free confidence when you're rallying across technical terrain. In conjunction with a low-friction shift cable, Shimano claims shifting requires 20% less effort. Other key features include an easy-to-adjust chain stabilizer for effortless fine-tuning, as well as Direct Mount attachment with compatible frames for a stronger and lighter mount interface. As a bonus for riders with older frames not compatible with Direct Mount, the included link attaches in a conventional manner.

    My, what a long cage you have.

    • Familiarity: I've put it through the wringer

    With the advent of 1x and the huge big cog, derailleurs have had to keep up with long cages. XT the best working, everyman components on the market. Shifts well and never needs adjustments.

    XT is the everyman groupo

    • Familiarity: I've put it through the wringer

    No, it's not XTR, but mechanically it is the same, and only a little heavier, but a good bit cheaper. I love XT and see no reason to go with anything else. XTR is for the racers with sponsors, XT is for the rest of us

    Big bang for your buck

    • Familiarity: I've put it through the wringer


    The XT rear derailleur's does shift cleaner than other XT products in the past. The clear advantage is Shimano's new clutch design to provide chain retention, so you can run a 1X configuration with a 11-46 cassette. If you have any questions on this product, I will be happy to help you out.

    Smooth operator!

    • Familiarity: I've put it through the wringer

    I bought this after Shae( She is great) from the bike dept at backcountry recommend it as part of the parts ( Race Face Narrow Wide Chainring, Shimano CN-HG600 11-Speed Chain,Shimano XT CS-M8000 Cassette, Shimano XT SL-M8000 RapidFire Trigger) to convert my baby (2016 Santa Cruz Heckler) to a 1 x 11. After a 100 miles the the derailleur is still smooth and is tougher that it looks. I had a couple of bad crashes that had me fearing the worst, however it is still going. I could not be happier; all done at a very reasonable price. My only regret is that i did not changed sooner to a 1 x11

    Great. Consider adding Goat Link

    • Familiarity: I've put it through the wringer

    I use this on a 11 x 46t XT cassette. It is crisp, however it does take a while to dial in. I added the Goat Link 11 and it made the derailleur perform incrementally better.

    Bang for your Buck

    • Familiarity: I've used it several times

    M8000 rear derailleur is pretty sweet for the money. Shifts crisp and smooth every time. It is more quiet if you pair it with a sram cassette and chain. Does the trick.

    Solid Performer

      I've had about a half dozen rides so far on my complete XT 1X11 set up, on mixed single-track, moderate downhill and serious climbs. So far I love it! I know it's not as light as the SRAM drivetrains, but the cost and simplicity of the drivetrain swap pays big time. No dropped chains, no mis-shifts. I'm really loving it. Coming from a 3X or 2X set up, I don't have the top-end road speed, but who cares! If you're thinking about upgrading, do it.

      This is my third XT rear der ad I've run one them on my other bikes. I tried Sram on my Yeti but went back to XT. Running this newer version on a 2x11. Shifts well and the chain stays on. Can't get anything better for the price and they are very reliable.

      With a 34T oval should I go for the med or long derailleur? I have not decided on the cassette yet. probably stick to 42 and get in shape.

      What cassette size will this handle? Or the longcage version? I need 11-42, but would like to upgrade to 11-46.

      Can I use this RD with a Shimano Saint 10sp shifter and Shimano XT 10sp cassette? I need to replace my Saint derailleur and would like to use this RD-M8000 if it's compatible with my current 1x10 setup.

      With apologies to Virginia, it is possible to run a Shimano XT M8000 rear derailleur with a 10-speed cassette and shifter. I did so for some 1,500 miles of the 2,000 miles I put on my bike last year and plan to carry over the same setup (Sunrace MX3 11-42T 10-speed cassette with Saint 10-speed shifter) this season. Shifting was smooth, precise, and immediate through the full range.



      I chose the M8000 after reading up on other experiences at MTBR.com, and because it offers an upgrade path to 11-speed and can better accommodate a wide-range cassette than the M786.



      Only criticism to date is having to replace the jockey wheels as the bearing for the tension pulley seized up.

      So I can use the medium length RD with the 11-42 cassette if I'm running it 1x11, right? The long cage is only required for the triple, right?
