Round Oval 104BCD 30T 32T 34T 36T 38T Narrow Wide Chainring Single Chainring for 6/7/8/9/10/11/12-Speed

Threaded so you have to run on the inside.

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

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.

I went up from a 30T Round to this 32T Oval Deckas, which is my very 1st oval, and I immediately loved it. Everything just seemed smoother and more natural. The thing is your feet still travel in a perfect circle so I didnt feel much difference in that regard. Instead, all the oval goodness is happening in the way that the chain travels around the ring and where stroke power meets with it. Long story short this has helped my climbs especially with slower, steeper, and technically more difficult routes. Quality is there and there is a slightly deep cut/longer tooth so the chain seats into the ring really well. time will tell how long it lasts but for $15 it's an affordable replacement when it gets worn out. Just ordered my 2nd ring for another bike. It's an old full sus schwinn that is my frankenstein restoration project. Downside, installation is not the easiest only because I could not find any specific markings that tells you how to allign the oval with your cranks and there are no instructions include. That being said it's pretty easy to figure out. This ring is great, and I highly recommend you give it a go.

The product fit perfect

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.

Bolted right up with out the snails. The oval chainring is seamless - power when you need it - easy when you don’t.. Same chain, same rear cassette rides like new. I will buy again and again. Thank you!

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.
