JGbikeElite Round Oval Chainring 104mm BCD 30T 32T 34T 36T 38T Narrow Wide Single Chainring for 8 9 10 11 12 Speed MTB XC Trail e-Bike Fat Bike Mountain Bike Bicycle

Seems like a decent for the price chainring. Some other reviewers said they had fitment issues and it was the same with mine. I had to file down the inside edges of the inner chainring to get it to fit properly to my crank set. It was very easy to do but still bothersome. After filing it down slightly it bolted right on no issues. It came with it's own bolts but I used the originals that I had. Only time will tell if it will hold up to casual riding.Update!I took my bike out for a pretty decent run with this chain ring on it and it performed flawlessly! I like this oval chain ring. I have been running a round chain ring from day one, but I could tell especially on the climbs that this oval ring made a difference. I'm not in the best shape, and the trails I ride have some decent climbs, and I would normally need to dismount and walk my bike. But I made it through the entire run without dismounting once. So it definitely helped. Would definitely recommend!

Very nice chainring, easy to install and good durability. I used it to climb Mount Washington on my gravel bike, 32T with a 48T cassette for 1.5:1 gearing (12% average grade for 7.6 miles). Not sure how much more of a real world durability test one can do.

Good budget sprocket. Comes in a good selection of colors. Also, round or oval. Haven't rode much with it yet but seems to be holding up.

Super easy and fast to install the Corby bolts had a little trouble grabbing into the crank assembly, but with some blue locktight they won't be going anywhere. The narrow wide construction prevented any chain drop all weekend, about 20+ miles of trails.

Everything about this is great. For the price I expected I would have to replace it once a year. With that said, it's been a reliable throw-away/spare part for 2 years now (on my second one) and a good reminder of when I need to do an overhaul on my bike.

Highly recommend. Easy to install and good hardware.

I purchased in 2020 but did not install until 2021 because my desired use was a 2x 10 derailleur system. I saw reviews indicating folks wanted to drop to 1x, but I did not want to give up the availability of my little ring to help with steep climbs.Based on my experimentation, downshifting off of the JGBike ring works smoothly, which is the most important aspect since that's kind of the point of running 2x... Mid-climb, need some help.Shifting back up to the ring requires a little attentiveness... There's a chance for slippage, but it's a while-riding relatively smooth operation. If the chain hits the peak teeth, they will slip down into their appropriate slots as long as you have some momentum and aren't pushing too hard on that initial shift. Once locked in, you're good to go!I did scrape a small part of the ring with a chain slip, but not a big deal, and love the extra speed the size provides on flat or downhill! These rings are aluminum but thick and able to withstand my 220lb 6'3" frame bearing down on this ring full force with no warping or breakage.

Could include instructions for proper orientation

I already had a 32t round which is wearing very well and thought I would try the oval, I have found climbing on wet muddy sections easier with the oval ring and so far very happy with it, i expect that it will work as well as the other one made from the same material, given the cost this was an excellent upgrade to the bike.I do have to laugh when i read reviews from people that recieve thease and complain that they are not round LOL they are not supposed to be ;).

Great for the money, but no means perfect. BCD was a perfect measurement, however where the internal lugs meet the crank, it was slightly out, by all of 0.1mm so i found myself gently filing it flush until it seated properly, no real problem for me, just my experience, and for the money was the best course of action. Runs perfectly well on the trails with the other bits i also purchased from the same seller - sunrace/deore/kmc. Done several high speed bumpy runs now, can’t really beat it for the money.

The bolts are not the correct size for single speed ring. It caused me lots of issues, bolts got stuck, broke drill bits trying to get them out and the when trying to grind slots in bolts so I could use a flat screwdriver I damaged the chain ring so it was completely useless to me. Very dissatisfied, supply the correct smaller single ring size bolts!!!

Used for a 1x10 conversion on my mountain bike. Very impressed. Looks great, fits well, nice simple gearing. I did notice that female threads on the fasteners aren't very clean. Some had burrs that prevented the bolts from going in but screwing the bolts through from the back cleared them out and then they can be Installed correctly with a bit of blue loctite.

This chainring was bent and broken while I was cycling with my child. Luckily I was going slowly, otherwise it would be a fatal accident. During these 5 months I have used it, my bike was in shop for 1 month to replace the motor. So 4 months of normal rides...
