Questions & Answers

Has anyone ordered the 30T ring, and how does it compare to the picture?

I placed an order for a 30T. It appears to be identical. The bolt pattern is the same. The color grey is the same. Graphics are kept to the absolute minimum.

Is there a set of mounting bolts included with this chainring?

IT'S NOT JUST THE CHAIRING THAT MAKES A DIFFERENCE.

Is this compatible with the Shimano XT M785 crankset? Are you interested in doing 1x12?

Unfortunately, this does not work for the reasons listed below.
1. The angle of the mount is unique.
2. This is for an 11-speed transmission, not a 12-speed transmission.

Selected User Reviews For SHIMANO SM-CRM81 XT M8000 1x Chainring

It's also fun and light, with a lot of engagement
5/5

If your converted 1x has a chain drop problem, this is most likely the solution. I put it on and haven't dropped a single chain since. It's also fun and light, with a lot of engagement. This is something I would strongly suggest. This is what I used to attach it to the Shimano FC- The MT700 crank is perfect for the job, though the chain needs to be adjusted. Depending on the situation, you may want to use spacers.

Bolt spacing is important
3/5

The Chainring seems to be of very high quality. The bolt spacing, on the other hand, is not readily apparent from the description. I threw away the packaging and now I'm unable to return it because it doesn't fit my mountain bike. It may have been a fantastic chainring in the past, but it is now completely useless.

Improved chain life and noise reduction, replacing the previous version SM-XXXXXXXXXXXXXXXXXXXXXX CRM80 (square shape type with a deeper cut)
5/5

br>The previous version is cool, but the chain is quickly worn out. After replacing the old chain with this new one, the chain life is much longer and there is less noise. br> I can confidently say that this CRM81 is superior to the previous CRM80!.

It's effective Other 4 bolt 96bcd cranks would not work on XT M8000 XT double cranks
5/5

This ring is only for the asymmetrical holes on the newer XT cranks. My 1 x 9 works well with 30 teeth. There has yet to be a chain drop. It's well worth the extra money to get this one rather than the less expensive ones that are likely to fit incorrectly.

There are no drops in this chainring
5/5

It's effective at what it's designed to do. It's just that I wish they made a 36t! The product is of excellent quality.
