Rated 4 out of 5 by 2 reviewers.
Rated 4 out of 5 by Mid range product for low price Had an issue at the start of 2013 with my front derailleur so ended up in the middle ring for most of the hard riding through till September. Had obvious wear and tear on the old middle ring so opted for a like for like replacement. I'm a big rider, 6'4" and 16stone and generate alot of power, so the middle ring coped very well with abuse for a few years before developing bad chain suck on any muddy rides through wear of the teeth. **Warning** be sure to check your chain wear before fitting new ring, a worn chain on new rings will have just as many problems as a new chain on worn rings. Sometimes you just have to get both! 11 February 2014
Rated 4 out of 5 by Good over all I use this as the middle chain ring (32t) on a Truvativ FireX GXP... I had to sand off the plastic on the inside to make it fit (clearance issue)... But the bolts and overall fit is perfect.... But it does it's job well and have been using it for 6 months (racing, all weather riding)... So I would recommend this product 29 September 2013

Would the 36t SLX chainring fit an XT M770 crank set? If not, please would you advise a suitable 36t chainring.

Answer: 
This chainring would not be ideal due to the spacing of the chainring teeth (for 9-speed). The M770 chainring is listed by Shimano as compatible; however the tooth counts that you require are not currently available.

The Blackspire chainrings are known to be fully compatible with Shimano cranksets.

Answer: 
The 32t version has a composite inner which may foul the tabs on your standard Deus XC cranks. The 36t version is a standard 4-bolt so will likely fit ok. If fitting different brands of chainring to the same crank be aware that the shifting pins/ ramps are likely to be in slightly different positions, so it may not be as smooth as if all rings were matching.
