    Wheel fast.

    Shift smoothly across everything from steep, rock-strewn trails to smooth-buffed XC loops with the Shimano XT CS-M8000 Cassette. Whether you're overhauling your trail bike's chewed-up cassette or converting to a 1x11 drivetrain, this 11-speed cassette shaves precious grams while standing up to abuse on the trail with its mixture of lightweight aluminum and robust steel cogs. Rhythm step gear progression ensures precise shifting without annoying ghost shifts on the trail. The wide range of available gears saves your knees from undue stress on lung-busting climbs, available in 11-40T, 11-42T, or 11-46T versions to suit your riding style and local terrain.

    Great product for a great price!

      Picked this up for my new Yeti SB6 build, its the middle of winter here in Park City so I haven't been able to put some miles on it yet. So far it feels great and I'm excited to rip around come spring time!

      Cost effective 11 speed

      • Familiarity: I've used it several times

      If you are looking to upgrade your bike to 11 speed and don't want to or can't get an XD driver for your wheelset, this is the way to go. Have had great success with running it with either Shimano or Sram rear derailleurs.

      Not Eagle range..but way more economical

      • Familiarity: I've put it through the wringer

      I was an early adopter of 1x tech. And with the right chainring, I can get the range I need for almost a 100% of my riding. That said, bikepacking, snow biking and epic long rides find me desiring a little more range (usually reserved for a bail out gear--climbing). As a shimano fan (I've got X0 too) I've used mods on 10 speed to get a wide range rear. And this past year, I used a mod to put a 50t on my shimano 11x42. But--that ramps are so spread out on the 50t that you sometimes notice the delay in the chain jumping up to 50t ring (as it waits to find the ramp--only four on a 50t). Enter--the shimano 11x46t wide range cassette. Its not quite 50t or Eagle but its a fraction of the cost, full shimano manufacturing magic (meaning it will just work) and no aftermarket do-dads to buy and fiddle with to install. This one went on my full suspension XC rig for the epic big mileage days we sometimes do here so I'll be able to granny down on those late day monster climbs.

      Does the job!!!

      • 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 RD-M8000 Rear Derailleur, Shimano XT SL-M8000 RapidFire Trigger) to convert my baby (2016 Santa Cruz Heckler) to a 1 x 11. After a 100 miles the cassette is doing great. I got the 11-42 with a 32T chain ring and so far i can climb anything here in Jersey. The cassette is on the heavy but that was not a concern for me. 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


        I already have shimano xt m8000 11/42 cassette on my rolf ralos wheels but this 11/46 is Not compatible with my 10 speed hub... grazes in the rays rim

        A Smart Choice

        • Familiarity: I've used it several times

        The only thing the M8000 cassettes give up to their XTR brethren is weight. Otherwise, you're looking at excellent shifts, surprising durability, and a wide range of gearing options. Not the first choice for obsessive gram counters, but probably the best choice for anyone else running a Shimano drivetrain.

        XT is where is at...

          Been riding XT on my bikes as far back as I can remember. Not a racer, I don't need the expense or weight savings (and associated loss in strength) of XTR. This cassette is bombproof for the price point. Matched with an XTR chain you can't go wrong. Pro Tip get that locknut to the full torque. 40nm is a bit of grunt, but you don't want it coming lose during a 27mile alpine downhiller...take it from me.

          XT is where is at...

          Love your review!!! I am the same way!! Thanks for your review I just ordered what you did with the xtr chain and m8000 cassette. I wanted a durable cassette not a race cassette. It seems like they don't design some of the racing stuff to last as long. I would rather have durability.

          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.

            42 tooth cog is amazing

              Amazing range, shimano quality enough said

              Works Great

              • Familiarity: I've put it through the wringer

              This Is just one piece of the awesome XT 11 speed drivetrain. It’s nice to have a reasonably priced 42 tooth cassette without having to piece something together with an aftermarket cog. Jumping up from an 11-36 to a 11-42 allows you to go up in tooth size in the front while still having some easy gears for climbing. Overall this drivetrain is great and a no brainer if you are looking to make the jump to 11 speed.

              When will you have the 11-46 ready to ship? I'm ready!

              If I currently have a rear hub running a 10 speed shimano cassette, will that hub be able to run this 11?

              Yes, shimano 11 speed cassette fits on the same free hub body as 10 speed. SRAM 11 speed needs a new free hub body. I am currently using the same hub for shimano 11 speed as my old 8, 9, & 10 speed cassettes. One of the benefits of the shimano design vs. SRAM.

              Are there any compatibility issues running this cassette with sram XX1 derailleur & chain?
