    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.

    The Workhorse Groupset

    • Familiarity: I've put it through the wringer

    I think that the XT groupset is one of the best you can buy at this point. They are fairly light, very reliable, and will last forever. Not to mention, it's super affordable! Easy to install and also really easy to maintain. Might not be the ultra light race set up you want, but is just flat out reliable.

    Best Cassette for my Bike

    • Familiarity: I've used it several times

    This was the best thing I could have done for my Surly Krampus. The stock 1 x 10 was tough to use for climbing. When I switched to 1 x 11 it helped tremendously for climbing and extended the amount of time I could spend on my bike. There is just barely enough clearance with my plus sized tires (29 x 3). The bike Gearheads really helped me in getting the right set up. Consulting them before buying may really save you a lot of time and frustration for your next set up.

    That's a big cog you got there.

    • Familiarity: I've put it through the wringer

    Who would have thought that one day the large cog would be bigger than your brake rotor. I was skeptical of 1x for a long time but riding it on a long bikepack in Baja made me a believer. The jumps between gears are a bit big in some cases but the shifting is smooth and the low end gearing is great for hauling a loaded bike up long mountain passes

    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

        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?
