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

    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...

      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 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

          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.

          Works Great

          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.

          Climbing goat

          • Familiarity: I've used it once or twice and have initial impressions

          I recently upgraded my 10 speed xt drive train to the 11 speed drive train, and have no complaints what so ever. Light weight for how big this cassette is, ramping is cut well, and shifts through each cog incredibly well, and durable. Shimano knocked it out of the park with what they have put together. Price doesn't get much better either for a solid 11 speed cassette.
