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.
- A cassette that solves the budget vs bling conundrum
- Blend of aluminum and steel cogs sheds weight where possible
- Gearing increments ensure you've always got the right gear
- Compatible with Shimano or SRAM 11-speed drivetrains

11 Gear of Fun
XT is the gold standard for Shimano MTN bike parts and this cassette fits perfectly into that standard. I bought this because my old one just had too many watts on it... over 3000 miles of dirt covered brutality in it. New chain and a new cassette = brand new bike feel!
Wyatt MaxwellEmployeeGood Casette
Paired with mine shimano xt di2 derailleur, this cassette is buttery smooth throughout all gears with regular chain maintenance. I would say this cassette is a close second behind sram's eagle drive train.

11-46? HUGE RANGE
HG freehub? NO PROPRIETARY HUB!
Classic stylings, great range, and reasonable pricing for a fantastic piece of componentry.

NickGreat Product - Perfectly priced!

Decided to upgrade from a 10spd to 11spd. Thought about saving a few $ and going with the SLX cassette. But, based on the price difference, I figured might as well pay the little extra. Happy I did. a Buddy of mine purchased the SLX blend ripley and converted to the M8000 rear derailleur at the same time I went m8000 full rear (xtr shifter). There is a noticable difference in how smooth the shift quality is on my bike vs his now. He went so far as to ride my bike, feel the difference, then come back to comp cyclist and purchase the XT cassette.

What a great cassette ,durable great price what also you can ask...
Blake T.Reliable, seems to be long wearing
- Familiarity: I've put it through the wringer
Reliable, even wear, works with any 11 speed chain. 12 speed would be great but this is a tremendous value.
robEmployee46 was what I needed
- Familiarity: I've put it through the wringer
The 46 tooth is just enough of a granny to make almost any climb doable.
switched from a 42 tooth and it was a great choice.
#1 HeadbandEmployeeShimano value and quality-thumbs up
- Familiarity: I've put it through the wringer
The shear volume of great reviews on the XT lineup speaks for itself. I'm running an XT 1x11 (46t) drivetrain and love it. Yes, there is a pretty large jump between the 37t and 46t granny gear but its nothing that's gonna ruin your ride. The 46t cassette I bought is the most cost effective drivetrain upgrade out there. You can retrofit your 10spd HG freehubed bike into an 11 spd 1x gear monster with just a shifter, cassette and chainring...that's all you need. Yes, there are prettier, shinier, more goldier cassette options out there, but for shear bang-for-the-buck upgrades, nothing beats the XT drivetrain. Good stuff to get your goods going.
Don MyersGearheadGood but cheap 1X11 solution
- Familiarity: I've put it through the wringer
This is great solution for anyone who wants a good but cheap 1X11 solution. Shimano cassette is made of great materials/construction, crisp, and effortless shifts. This cassette it does the job well, like shimano XT components typically do.
Mike NewberryEmployeeGreat componentry
- Familiarity: I've used it several times
Shimano makes the best stuff...love the 42T (up from the XTR 40T). Smooth shifting, easy install, etc. Run a Shimano chain w/quick link.
Porter TrappGearheadThe 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.
Christian CerasoBest 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.
Steve CookEmployeeThat'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.
Update. Still running strong with no shifting issues. Lots of miles on cogset.

I bought my wife the 11-46 because she excels at downhill riding far more than the uphill stuff. Now she can climb anything. Compatibility questions? Hit me up at adickinson@backcountry.com
Josh RGearhead11-46 has big jump on the low end...
- Familiarity: I've used it several times
See my prior review...love shimano stuff...it 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.

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...
William H.Soooo Pat ... are you sayin' you made the 11 speed 11-46 into a 12 speed by adding the 42 teeth to it?? How so?
Patrick P.Hi William,
Sorry for late reply.. Cassette still 11 speed, i did removed the 17t and what i have right now is 11-13-15-19-21-24-28-32-37-42-46.
Do you need a long cage to run the 46?
