    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.

    • Shadow RD+ with stabilizer switch prevents dropped chains

    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 used it several times

    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.

    Bang for buck

    • Familiarity: I've put it through the wringer

    Bought this because I ripped my XTR derailleur off my bike with a rock. This derailleur shifts and performs similarly to the XTR. Its a bit heavier but only slightly and cost half as much.

    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.

      Get an XT

      • Familiarity: I've put it through the wringer

      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.

      Derailleur sheared

      • Familiarity: I've used it several times

      First of all, I want to say the customer service is top notch. I have now become a customer for life and will even stay true if the price is a bit more than the competition .
      That being said, I have run all XT m8000 on my bike. I recently replaced this derailleur due to a rock collision that bent the cage like a soft taco. After the new component was installed by my lbs (because my wife had it done for me while I was at work)...I took it on three rides...8 miles, 16 miles and 5 miles, all on hard packed singlet rack with minimal climbs. On the fourth ride day, I was riding the bike at the trailhead (not on the trail) and the body of the unit completely sheared I to three pieces. The connection point of the hanger had a small piece, the gear mech cable had a small piece and the main unit. No hits, no stress, just sheared into pieces. I have no idea how this could happen besides a bad mold on this particular batch. I will still use XT m8000, it shifts like butter and have had no issues before. The customer service rep was on target and helped get a new item in the mail on the fast track since I have a race in 8 days. Fortunately I was under 30 days and the customer service dept honored the return policy. I am a customer for life, competitive cyclist is great!

      Super Quiet

      • Familiarity: I've put it through the wringer

      The 11 speed XT drivetrain is sick and the derailleur is a large part of what makes it great. The clutch mechanism keeps everything quiet and is now easily adjustable with an external screw. The medium cage is perfect for a single ring setup. Overall this drivetrain is great and a no brainer if you are looking to make the jump to 11 speed.

      Gotta go 1X11

      • Familiarity: I've used it several times

      Just picked up an 11 speed xt drivetrain for my bike, and even though I haven't put in a lot of miles, I am impressed so far. The weight is great, the new clutch is awesome, with a great new lever, easier adjustment, and a better feel. Shifting is very smooth, even the leap in to the 42 tooth cog. Haven't tested durability yet, which i think is a good thing i haven't had that situation for, but if it is anything like my 10 speed xt, then we still have a very durable system

      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.

      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?
