Wheel fast.

Keep your wheels rolling down the trail with the Shimano XT CS-M8000 Cassette. Packed with 11 gears of fun, this cassette features a combination of aluminum and steel cogs to keep weight down while staying tough enough to handle all the torque you can throw at it.

While the XT cassette holds onto a little bit of extra weight compared to its XTR sibling, the CS-M8000 stands out as a perfect choice for riders looking for top-level quality at a more affordable price point. Shimano engineers this cassette with rhythm step gear progression, ensuring precise shifting every time to eliminate pesky distractions such as ghost or missed shifts out on the mountain.

The Shimano XT CS-M8000 Cassette is available in two sizes to accommodate differing ride styles and needs, and the enormous 40, 42, or 46t cogs are knee-savers with one-by drivetrains. Both the 11-40t and 11-42t options feature a wide cassette sprocket and optimized gear steps to move the chain smoothly across their ranges and get you smoothly across varied terrain.

  • Aluminum and steel cogs
  • Three sizes: 11-40T, 11-42T, or 11-46T

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

      You are wrong. The 11-46 cassette fits on the same standard shimano freehubs and shifts quite nicely, btw.

      Greater Range

      • Familiarity: I've put it through the wringer

      Chose this XT to mate with the one-by system I switched over to. Loving the new range of cogs and simplicity of a one-by drivetrain.

      durable dependable, no worries

      • Familiarity: I've put it through the wringer

      it's kind of the go to cassette, hard to wear out, never any issues. no a lot more to say about the XT but thats probably a good thing.

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

      Hey Dusty! Looks like the estimated arrival time for first shipment of the 11-46 to get in is 8/09! If you or anyone else has any questions on it or would like any help placing an order feel free to reach out to me! Cheers, Connor

      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.


          • Familiarity: I've put it through the wringer

          This cassette has been great! Shifts smooth and is very durable. The one downside to this cassette is the weight, if you are looking save weight spend the extra $$$ for the XTR.

          Smooth shifting.

          • Familiarity: I've used it several times

          Good for the price 11 speed cassette. Works great with my XT rear derailleur, and chain. Chain moves up and down so smooth.

          42 tooth cog is amazing

            Amazing range, shimano quality enough said

            Do you think I can run the 40/42 on a Cannondale caad8 105? I've seen peopl on YouTube running a 40-42 tooth lol speed on their 105 but I'm always skeptical about what people post on YouTube
