Must get and well worth it for 1X conversions
Excellent value and well worth it. Very nicely machined and have ZERO problems with figment. The oval round idea is not new ( Shimano was one of first to use it over 20 years ago but called it Bio Pace and it was on all 3 front chainrings). As a 1X ,it’s great and you do feel the power increase as the oval side comes round the top part as you stroke down the crank. The value is the biggest benefit as others are twice to three times more expensive. Installed on Marlin 5 upgraded to a 1X drive with a hollow tech crank set. No complaints and well with conversion in both weight saved and looks

Chainring
Fits my cannondale trail five perfectly, seems durable. Gives a bit more torque when riding through snow. I’m impressed

A Nice Chainring
I bought this chainring for a winter commuter bike. I typically use Raceface n/w chainrings, but I couldn't justify spending $45.00-$50.00 for a winter commuter. I thought I would try this brand, but I was skeptical of the quality. I am pleased with this product and it works well. The fit is not on par with the more expensive Raceface chainrings. I see reviews complaining about the chainring not fitting correctly - I had the same problem. However, ten minutes with a Dremel tool fixed that. I've taken this on many rides and I've had no problems with chain drop. In my opinion, for an inexpensive chainring, this does pretty well.

Looks good and seems like good value
This chain ring looks to be well made and works fine. The only issue I had was that in order to install this on my SRAM crankarm I had to grind the mounting tabs to actually fit onto the spider arms. The bolt holes are fine and spot on at 104BCD but the tabs were each about 0.5mm too long so the ring would not fit onto the crankarm. There is very little spare material around the bolt holes so grinding has to be very minimal and carefully done. I milled about .1mm at a time and kept checking fit until I got the ring to slide onto the crank arm. (this can easily be done with a dremel and grinding bit) It is best to do this very gradually so that you remove only the material that is necessary and not a bit more. (Keep in mind, I mounted this to a SRAM crankarm, this many not even be an issue with other crankarms). All things considered, this is good value for the money spent and worth the extra work to get it installed.

Nice 36T Chainring
I upgraded my bike from a 32T to this 36T chainring to get more speed out of my bike. This was a nice upgrade because I was able to pick up an additional 3 mph with no additional effort.

Great product
This is a great product that is light and inexpensive. I have purchased several of these and they have all held up and worked flawlessly.

Fantastic for those of us who bike uphill.
I purchased the 38t as I am more of a long distance biker on roads. Going from a round to oval chain ring, I'll tell you. You can tell that its easier to pedal. You get more power when you need it and less when you dont. Although, if you dont ride hills or inclines, this will not be as useful to you. On normal flat roads, this is, at best, fancy. You'll get looks about it but unless you're trying to pedal up a big hill to a trail you want or up a really big incline to try to get somewhere, it's not as useful.
