Winning the one-by race.
The latest generation of Shimano's road and mountain drivetrains has seen some pretty extravagant changes. Of the changed groups, none may be as heavily altered as the new XT, and the biggest changes worth mentioning may be those resulting in the XT FC-M8000 1x Crank Arms. With trickle-down technology like Hollowtech II construction and smaller bearings with improved seals, Shimano's XT Cranks may be winning the race to provide the self-sponsored racers of the world with one-by drivetrains.
While the improved bearings are nice in that they're lighter, smoother, and have less chance of debris gumming them up, we have to admit that bearing issues have never been one of our great concerns with Shimano kit. Ditto crank arm stiffness, and the Hollowtech II cold-forging process is a big reason why. Despite making the crank arms hollow to save weight, Shimano's cold-forged construction doesn't sacrifice strength or efficiency, so the crank arm assembly is both lighter and stronger than designs with solid arms. Installation is just as easy as you'd expect, with the simple, durable, and effective thru-axle and pinch bolt design returning to celebrate yet another year as the amateur mechanic's favorite system.
- Upgraded crank arms ready for everything on-trail
- Lighter construction delivers impressive durability
- Improved bearings roll smoother and are better protected

Shimano makes the best cranks! Use them!

I'm replacing the OEM SRAM drivetrain on my '16 Yeti ASRc with Shimano...can't wait to ride this Spring!!

Shimano's tried and true XT crank optimized for 1x and hollowed out for lightness. Just a great crankset at a great price. Love it, I also went with the absolute black chainring and love the system works.
Brendan LewisGreat Crank
- Familiarity: I've used it several times
This crank was simple to install in place of the older XT crank I had before. It's stiff and light, Set it and forget it!
Neil V.Will this fit my 2016 beargrease carbon x7? I believe it has a 41x121 bb. Or do you have better/similar recommendations from raceface? Thx!
Victor C.They have boost and fat bike sizes. Cheer´s

Great crank

This is a really great crank. Not too pricey, but good and stiff, and looks good too! I put a red AB oval ring on mine, and it is a sight to behold!

I purchased a stock Specialized Rumor for my wife and have been upgrading components as time/money permit. For $95 you will never find a better set of crank arms. I am changing her over from a 3 x 9 to a 1 x 10 system with XT all the way through. Great purchase, easy to maintain and will take any physical abuse you want to apply to them.
Matthew V.Does this crank set come with chainring bolts?
Victor C.Yes, they come with chainring bolts :-)

Press fit or threaded bottom bracket ?
Scott GartmanHi Blair,
These will work with a few different bottom brackets, it will depend on which frame these are going into.
Todd C.Best bang for your buck!
Very nice and light crankset
Mark Smith Stoked!
I have always wanted XT cranks. I can't believe I got them at such an awesome price with free 2nd day shipping. Love the goat!
Peter C.I interes 180mm you have?
Dennis B.Works great!

These are used on a trail bike with a 32 tooth OneUp ring. Chain line is great, no issues after several hundred hard miles.
Eric B.Why would this only work with 11 speed? Couldn't it work with a 10 speed single as well?
Aaron S.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.
John BamfordEmployeegood cranks, no BB
The tech specs made me beleive that this came with a shimano bottom bracket, but the crank arms do not. Still real solid crank arms to say the least but wish for the price it came with a bottom bracket, for the same price I could have gone with a zee crankset and it would have come with chainring and BB
Eduardo B.Hi,
I have a Scott Spark 950 with shimano fc m622 crankset, will this xt crankset fit with the bottom bracket installed? I think its BB92
Ruben HernandezDoes this crankset come with a bottom bracket??
Matthew PizzaHi Ruben,
No, these crank arms do not come with a bottom bracket.
If you have any other questions, feel free to reach out to me directly.
Thanks,

I love the new 1x11. I have waited some time for XT to come out with the 1x11 for a upgrade and it was well worth the wait. Flawless shifting and light weight.
Cory DavisGreat way to go 1x

Shimano XT has always been my number one choice for drivetrain and brakes. The value provided is the best in the industry and as the years go on, XTR technology always trickles down to the XT level.
The new M-8000 series cranks are no exception to the above statement. The cranks are plenty light and stiff and are easily mounted with their thru axle and pinch bolt design. It is worth noting to absolutely follow the torque specs for the pinch bolts printed on the non-drive side crank. Tighten the bolts in sequence, to assure even clamping force, make sure the plastic clip is seated and flush, and use a torque wrench to achieve the recommended setting. Ride your bike then check these again.
All in all these are a great crankset, packing performance and value in a sleek black package...About that black finish-
The black coating is wearing off very quickly due to shoe contact with the crank, leading to a polished surface beneath. This doesn't really bother me, but it can be a bit unsightly. A person could use one of the many aftermarket crank protection films on the market, or some clear 3M tape.
I just received this crankset from Backcountry and it does not appear to be optimized for 1x. The spider has bolt holes for two chain rings. I already have a single narrow-wide installed on a 2x crankset. It looks like this "1x" set will still give a chain line as if running a double. I assumed this crankset would only take single and would position it toward the large cog side by 2 or 3 millimeters.
