XT M8000 1x Crankset
The new Shimano 11-speed XT group borrows a huge swatch of technology from last year's updates to the top-end XTR line, resulting in a component group that closely mirrors its more expensive sibling and offers a more affordable option for those of us on a budget. The XT M8000 Crankset keeps the gears turning with advanced Hollowtech II construction and chain management features to keep you on track and zooming down the trail.
While Shimano's bearings have always been solid, the M8000 gets an update with smaller bearings and improved seals for an even smoother ride that efficiently transfers power into forward motion. The Hollowtech II cold-forging process results in crankarms that are both stiffer and lighter than most solid crankarms, and they install in a flash with a thru-axle and pinch bolt design.
The M8000 chainrings bring some additional chain-retention features to the table to make this crankset hum, including Dynamic Chain Engagement (DCE) design, a special tooth shape that results in a claimed 150% better chain retention than standard chainring teeth. The DCE tooth shape is a signature squared-off and slightly hooked profile that grabs the chain when it needs to, and lets it slide by at the back end of the pedal stroke for smooth power over any terrain.
The XT M8000 1x Crankset is available with several chainring size options, allowing riders to maximize the trail ride experience based on their specific gearing needs.

What do you think about this product?

Gets the job done
- I've used it once or twice and have initial impressions
They look elegant on the bike paired with my xt 32t chainring and full xt drive train. You cant go wrong with the price for these aluminum cranks, however if I had the money for xtr cranks, I would go buy those in a heartbeat!

Sold as 1x, still uses 2x spider
- I returned this product before using it
I bought this Shimano XT 1x specific crankset for my conversion from 2x10 to 1x11 thinking it would help achieve the proper chainline and hopefully avoid any issues when backpedaling on the largest two cogs. After receiving the crankset delivery, I discovered that the only difference between this and the 2x version is that this contains 4 chainring bolts and no chainring (as I expected), while the 2x has 2 chainrings and 8 bolts?! I thought a mistake had been made in what was sent to me when I made this disovery. This 1x crankset actually uses the same 2x spider as the XT crankset sold as 2x!! Sure, a 96BCD ring is supposed to be attached in the larger chain ring position, but it seems like a crankset sold as 1x specific would have a spider for only one chain ring positioned a bit further in toward the non-drive side. Normally, with a 2x, we avoid crosschaining between the big ring and three largest cogs and also avoid using the 3 smallest cogs while in the small ring up front. With a 1x, we need to ride in all 11 cogs and need to move the chain line in a couple millimeters. It's common for many to experience the problem dropping the chain on the largest two cogs while backpedaling, I think this set is getting returned. XTR 1x crank apparently has a true 1x spider, but the price is more than I can justify. I'll probably just keep the old 2x XT cranks since they will have the same chain line and I can reuse my existing Wolf Tooth narrow-wide single ring. At this time, the Tech Specs on this product page indicates Compatible Components: Shimano 11-speed 1x drivetrains AND Rings: 1 Note that there is no indication that it is also compatible with 2x drivetrains and 2 Rings. Yet, the Tech Specs do indicate multiple options for Arm Length and Chain Ring Sizes: Arm Length 170 mm, 175 mm Chainring Sizes 30 t, 32 t, 34 t It would save a bit of hassle if the website description and photos made it clear that the spider wasn't 1x specific on the Shimano XT M8000 (1x11S w/o CR). In my attached photo, you can see that the spider has bolt holes for two rings. Hopefully this helps others avoid purchasing this crankset in hopes it will achieve an optimal chain line for a 1x drivetrain.

Anybody from CC care to clarify this? One-up specifically addresses the chainline from the double spider in this case by adding an offset to their chainrings for the M8000 series cranksets. Does the Shimano M8000 single speed chainring have a similar offset to the One-up rings? I suspect this is the case because Shimano ships the 1x rings with 11.4 mm bolts vs. 9 mm bolts with the 2x rings, but would like some confirmation.

Above post is non-sense since the 1x specific chainrings from Shimano have the proper chainline spacing built into them when using this crankset

Better than ever!
- I've used it several times
XT stuff is the real deal. With the latest update, XT honestly feels like XTR. Don't get caught up in the status race. Unless you're a really serious racer, it's hard to make an argument for XTR from a value perspective.

Jump off the fence if your thinking about buying this.I bought & installed XT M8000 1X 175mm/32t paired with XTM8000 11sp.11-42t and the XT RD M8000 on my GT 29er Zaskar Elite Hard-tail.I made the jump from SLX 3 chain-ring.So Freaking glad I did,love it.Buy it,you will not regret it.

Will this fit an 8 speed Shimano XT? More teeth? What's the advantage?
September 12, 2019
Do you have a weight on these? Thanks
June 29, 2017
Is the bottom bracket included?
June 30, 2017
The bottom bracket is not included with this crankset. The bottom bracket you will need will depend on the frame you're installing the crankset on. Feel free to reach out to me directly and I'd be happy to steer you towards the correct bottom bracket!

is this set available in boost or do i need to buy the arms and rings sperately?
August 3, 2016
Hey Ian, for a bike with Boost spacing, you'll want the Shimano XT M8000 Boost 1x Crank Arms ( SHI00AX ) paired with the Shimano XT M8000 1x Chainring ( SHI008O ). Let me know if you have any other questions or anything I can help out with - feel free to give a shout to my direct line 801.204.4547 or email! Best, Connor

February 22, 2016

February 23, 2016
Hey David - With the Shimano XT BB-MT800 Bottom Bracket (Item# SHI008U) this XT Crankset will work on your Bronson. Feel free to shoot me any additional questions. Kyle L. - email@example.com - 801-736-4337

I currently have 1 X 10 Shimano set up. Will this crank work with 10 speed gearing or only 11 speed?
January 19, 2016
Hey James, I chatted up Shea from Competitive Cyclist and he says it WILL work with a 1X10 set up.

Whats the difference in the XT M8000 that comes with the chainring and the "FC" version where you buy the crank arms and chainring separate?
December 31, 2015
There is no difference. They are the same parts, we simply offer the package in addition to the individual parts.
December 15, 2015
looking at this 1x crankset. What else will i need to upgrade? thanks
December 20, 2015
Hey Ian W, It depends on what bike you are putting these cranks on and what components you have now. Feel free to shoot me an email so I can help you figure out what else you might need. Dan Be. firstname.lastname@example.org 801-736-6396 ext 4999
September 30, 2015
Hi, is this a complete crank, bottom bracket and ring set up or just the crank arms and chain ring?
September 30, 2015
Hey Blakely, This is just the crank arm and chain ring, the bottom bracket is not included. Are you looking to upgrade components on your bike or switching to a 1x11 drivetrain? Feel free to shoot me any more questions about Shimano parts or anything bike related. Kyle Expert Gearhead email@example.com 801-736-4337
