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.

Gives a bit more torque when riding through snow. I’m impressed ### ⭐⭐⭐⭐⭐ A Nice Chainring *by G***. on January 24, 2021* 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. ## Frequently Bought Together - DECKAS Round Oval 104BCD 30T 32T 34T 36T 38T Narrow Wide Chainring Single Chainring for 6/7/8/9/10/11/12-Speed - BNVB Bike Crank Arm Set， 170mm 104 BCD Mountain Bike Crank Set with Bottom Bracket Crank and Chainring Bolts for MTB BMX Road Bicyle, Compatible with Shimano, FSA, Gaint (Black/Red/Silver) - DECKAS Round Oval Chainring 104BCD 32T 34T 36T 38T Narrow Wide Chainring for 6 7 8 9 10 11 12 Speed Chains --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/273026365-round-oval-104bcd-30t-32t-34t-36t-38t-narrow-wide](https://www.desertcart.sn/products/273026365-round-oval-104bcd-30t-32t-34t-36t-38t-narrow-wide) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-31*
