Keep moving forward.

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.

Better than ever!

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.

Is the bottom bracket included?

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?

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

Unanswered Question

Can the XT 1x be converted to a 2x if desired. are the crank arms the same for both the 1x and the 2x

will this fit a santa cruz bronson frame 2015? And what length should a certain rider chose? 170 vs 175

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.

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.

I currently have 1 X 10 Shimano set up. Will this crank work with 10 speed gearing or only 11 speed?

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?

There is no difference. They are the same parts, we simply offer the package in addition to the individual parts.

looking at this 1x crankset. What else will i need to upgrade? thanks

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.

Hi, is this a complete crank, bottom bracket and ring set up or just the crank arms and chain ring?

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.
