Shimano XT FC-M8000 Single Ring Crankarms

Rider Tuned for any Terrain

The long-awaited Shimano XT 11 speed drivetrain has made its grand entrance! The new Shimano XT Cranks are beautifully forged out of aluminum and turn on an updated bottom bracket that reduces both the weight and bearing drag, while improving its performance in muddy conditions. Through Shimano’s proven Hollowtech ll technology, the XT M8000 Crankarms receive a shot of stiffness and more weight savings. Additionally, the asymmetrical bolt pattern strategically places the strength spots where the most pedal force is exerted, providing more stability and trail-crushing responsiveness.

Pair these cranks with the appropriate Shimano single chainring and shred some trails!

I bought these cranks to replace the deore cranks which came stock on my bike and had developed an unfixable "creak". The XT cranks work great, no creaks, good stiffness, look great and are properly light. Add in the great value and its a no-brainer which crank to pick.

I bought a full 1x11 XT m8000 drivetrain. The crankset was the last part I purchased. It has such a bad chainline in comparison to the last race face cranks I was using that it seems unsafe to use the two largest cogs on the cassette. This is with the corresponding XT chainring up front too. Considering that it is a whole set designed for use with each other it is very disappointing that it is such a bad match.

Don't be fooled, you are not buying a 1x crankset here. It is the same crank for a 2x set up. What this means is, in order for the crank to work properly with an 11 speed cassette you would have to use a granny ring and front derailleur. Otherwise the chainline from the large front ring to the large rear ring is far too extreme (can't stress this enough). This crank is falsely advertised as a 1x crank and it is not designed to be.

With this crank, if you need to backpedal even less than half a turn in the two largest cogs, you will drop your chain down the cassette. I feel that it is unsafe for this reason. If you are on a technical climb and need to backpedal to avoid an obstacle, you may as well just forget about it. Please note that this issue occurs with other crank sets too but this is the worst I have seen it.

There are options to buy other chainrings like one made by One Up. They say they correct the chainline to 49mm from the 50.4 that it originally has. But I can not verify if this is true. I also don't know if they are just sticking washers behind the chainring. Either way, SHIMANO should not be advertising this as a 1x set up. I feel like I have been taken for my money here and I wish that I had gone another route.

It is rideable and it indexes just fine but with the extreme stress of the angle of the chain due to the poor chainline, I have deep concerns that the chain will eventually break while riding or it will drop and either way cause injury.

Hope this helps future customers.

Comments about Shimano XT FC-M8000 Single Crankarms:

This is a Shimano crankset, and that means that it's about as aluminum gets, which I guess some might argue is actually as good as anything we've got right now gets, but in any case, this seems like a really well-made crankset, at a very good weight and price. The only things I don't like about these cranks are the finish, which is gets wrecked if you hit it ( I liked the old silver arms for that), and the the new asymmetrical spider. It limits the rings you can use, though there are many good options from Shimano and Wolf Tooth, and really just seems kind of pointless. I'm sure there are good arguments for it, but I still wish they could just make more cross-compatibility in all of this stuff, for cryin' out loud!

Comments about Shimano XT FC-M8000 Single Crankarms:

I bought these when I converted my 2014 Remedy to a Shimano 1x11 drivetrain. I didn't want to spend a lot of money so I settled on these. They've ended up being a great value. My only complaint is that the writing on the side of the cranks has already started to rub off after only 4 rides, but since this is purely cosmetic, it's not a big deal for me.

But honestly my cranks are amazing too.

I couldnt be happier with how they work, how easy they were to install, and how great of a price I got on them. Only ordering knockoff parts from China was cheaper. I searched EVERYWHERE.

XT all the way...

By Ryderjin

Comments about Shimano XT FC-M8000 Single Crankarms:

Has there ever been a reason to NOT buy Shimano XT? Sure, XTR is shinier, and SRAM stuff look great... but with XT, you get 100% performance at consistently the solid value.

Crankset is solid. Build is better than ever!

BTW, I dropped down in length (170 from 175), and adjusted my gearing just a tad lower... and for my height (5'9"), it just feels right! I really do notice a difference in my knee and my back. In fact, it makes me mad that I've been riding a stupidly long crank for so many years!

    This description is confusing. Is this for a 1x11 or is it compatible with a 2x setup? I'm looking for shorter crank arms for a 2x10 deore crankset.
