Didn't work for me at all. I was planning to use this as a replacement for the 2nd ring on a Race Face crankset. Big ring replaced with a bash guard and this was going to take the space of the 2nd ring to make it a 1x10 setup. I was really excited to see the way this was threaded, but it became clear that the tolerances were off. The space for the big ring is just a hare bigger and it looks like that was what this was engineered to - unfortunately, that made it too small for the second ring space.Like others have said, the bolt holes line up but it doesn't seat correctly on the crankarm. If you want to go through the hassle of grinding it down, you can do that, but I really didn't feel like taking a Dremel to a brand new ring.

Had to grind it a little to make it fit but it worked great once I got it bolted on.

Upgraded my entry level 8 speed mtb to 1X and used this chainring on the front. I've got over 100 mi on it and have never had the chain jump off yet. Couldn't be happier especially for the money. Looks great too.

This chainring didn't fit on the middle position of my truvative isoflo crank. It did fit on the outer position; however, at this position there is greater cross gearing that is causing wear on the narrow teeth of the ring. Also, on the 30t the mounting holes are very close to the teeth, so I'm worried that the chainring will snap if I bottom out on a rock.On the plus side, the chain has not jumped the ring. It's been solid.I have this paired with a 11-40t cassette in a 1x8 conversion. It works. I've been pleased with my first four rides.Don't expect this ring to last forever.

used this Gear ring for the first test conversion from 3x9 to 1x9. the included bolts made this easy. i quickly removed my shamano Saint triple cranktook all the old gears off. droped this right on (lettering out) used the included bolts and put everything back together. this replaced the middle 32 tooth ring. my cassette is a 9 speed 12-36 and a long cage deroe rear derailer. i took it for a quick spin and like the range. i have on my Hardtail 26er. i like the simplicity of 1x i plan t install a zee10spd short cage (will handde the 12 to 36 and give me a clucched dear derailer. and use a sram 9 speed shifter. or add in a 10 speed cassete . will be going full blown 1x11 on my FS now that i know i like the configuration. is it wares out i will probibly replace it with a race face or wolf 30t but for 19.99 it was worth it to see if i would like the change. I DO! good macineing nice and light and includes the bolts what more can i say......

I had a professional bike tech install this on my 2015 Diamondback Hook 27.5 MTB, which was dropping the chain seemingly every 5-10 minutes of riding. I also spring for a new WTB 8-speed chain, and I've had solid shifting with no dropped chain ever since. The mechanic thought I was wasting my money and said my factory chainring was only about 3% worn; I acknowledge that the teeth were still in good shape, but I keep see when riding how warped it was. Thing ring seems more rigid. For the price, I'll be content even if it wears out in 2 years. It's a simple, inexpensive replacement.

Whats not to like? I converted my older full suspension to a 1x with this and it was a super easy job. Nice color options too and it comes with hardware to mount. It's threaded so you don't need to use the back side of the traditional barrel type hardware. I added a Race Face bash guard and a bit longer hardware to compensate for the extra thickness. I highly recommend this if you're considering.
