    Wheel fast.

    Shift smoothly across everything from steep, rock-strewn trails to smooth-buffed XC loops with the Shimano XT CS-M8000 Cassette.

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.

    11-46 has big jump on the low end...

    • Familiarity: I've used it several times

    See my prior shimano just works. That said, the 11-46 leaves me a little puzzled. Bought it for a new bikepacking rig set up 1x--that is, a bike I'm going to lash a bunch of stuff too, up to 20lbs of water at a time and go ride singletrack for a few days on end... As such, I'll spend a fair amount of time twiddling between climbing gears and I find myself missing a 42ish gear... The 46 bailout is great. But the next step is 37. For regular mountaing biking or flatlanders wanting a bailout gear, this is probably great as it maintains a nice spread across all the other 10 gears. But for my intended use in the rocky mountain west, I could ditch the 11t in exchange for more choices for climbing.


    • Familiarity: I've put it through the wringer

    I really like this Shimano 11 speed i bought two cassette one XT 11-46 for my Warden and SLX 11-42 for my other bike to upgrade from 10 speed.. Instead i modify the 11-46. disassemble 11-42 and added the 42 teeth to 11-46 .. 'Just for fun' and so far so good cassette is working just fine...


    1 X 11 Upgrade

    • Familiarity: I've used it several times

    I have been making my own 1 x 10 systems for a few years now with XT cassettes and a wolf tooth 42t. Finally decided to upgrade to a 1 x 11 system using the XT 46t.

    The Shimano XT systems never fail. You may add a few grams of weight over the XTR, but for half the price you can't go wrong with XT. The entire XT product line is bullet proof.

    1 X 11 Upgrade

    Excelent price-quality-durability ratio

    • Familiarity: I've put it through the wringer

    I´ve been using a mix of Shimano 1X11 for 3000 Km (Rear derailleur and shifter XTR M9000, Crank, Chain and Cassette 11-42 XT M8000) and it has working flawlessly, shifting is smooth and quick, even under load on step climbs, So now that my cassette is coming to the end of its life I will stick with this mix. Now shimano relases the 11-46 cassette, I would love to purchase one on this range to increase the number of teeth in my front chainring and gain speed, but would the 11-46 work with XTR RD-M9000 Medium Cage Rear shifter?

    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.

            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?
