Anodizing is wearing a little faster than other chainrings I have had, but for the price I think it is great. Used on a 9 speed touring bike I commute on. ### ⭐ One speed *by T***S on Reviewed in the United States on December 12, 2019* This sprocket will only fit a one speed. I have an 8 speed shimano w narrow chain and the sprocket would not mesh(new chain). I took the sprocket to my one speed and it fit perfect. ### ⭐ Not working on all bikes *by J***E on Reviewed in the United States on October 9, 2019* This does not work on my bmxrace bike, sproket fit on fine and was 44 t like i ordered, but the teeth are too thin , this is only for a 1/8in chain dont buy if you have a thick chain --- ## 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.tn/products/76333695-cooloh-single-chainring-40t-42t-44t-46t-48t-50t-52t](https://www.desertcart.tn/products/76333695-cooloh-single-chainring-40t-42t-44t-46t-48t-50t-52t) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-19*
