I’ve gone from 34 to 36 and now 38.. cheap and cheerful and to be honest feel as good as items 3 or 4 times the price. ### ⭐⭐⭐⭐⭐ Bargain *by G***E on 9 January 2021* A cheap narrow wide ring with bolts, what's not to like? Like all Al rings gotta be careful not to bash as it doesn't bend back like steel. Graphics a bit much but worked on my 2x9 with a bit of fettling for chain clearance on inside and changes fine ### ⭐⭐⭐⭐ Snail chain ring *by N***S on 4 April 2021* What can I say, it works fine so far. The snail brand name is printed on one side and it's blank on the other, enabling you to flip it over and have a passion black side showing (preferable) (lol) It's narrow wide and made out of aluminium. At £10.99 it was the cheapest 1x nar/wide on Amazon, but the quality looks to be pretty good regardless. I've coupled it with the cheapest crank and external bottom bracket listing on Amazon (in a ghastly red chrome, with hilariously unpronounceable chinglish branding), both of which coming in at under £50! Does it work? Yes, it works great for my work bike. Is it strong? As strong as needed to ride to work. Would I trust it on the trails? Nope. ## Frequently Bought Together - Chainring 104 BCD 32T 34T 36T 38T Narrow Wide Single Chain Ring with 4 Pieces Sprocket Bolts for Road Bikes, Mountain Bikes, BMX MTB Bike - Boao Chainring 104 BCD Chainring 32T Chainring Narrow Wide Single Chain Ring with 4 Pieces Sprocket Bolts for Road Bikes, Mountain Bikes, BMX MTB Bike(36T,Black) - KMC Unisex - Adult X9SL Ti-N X9 SL 9 Speed Chain, 114 Links --- ## 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.gr/products/209750741-boao-38t-narrow-wide-chainring-104-bcd-with-4-sprocket](https://www.desertcart.gr/products/209750741-boao-38t-narrow-wide-chainring-104-bcd-with-4-sprocket) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-11-14*
