I did need to pick up a crank puller, but this product bolted right up and required very little rear derailleur adjustment for proper function. ### ⭐⭐⭐⭐⭐ So far so good. *by on Reviewed in the United States October 3, 2025* I haven't ridden the bike on any trails yet but the crank chainring is smooth. No skips in the chain when pedaling. The bike overall looks cleaner with out the front derailleur and multi chainring crankset that were on it. ### ⭐⭐⭐⭐⭐ Held up to a year of commuting *by on Reviewed in the United States April 5, 2024* For a chainring/crankset combo that had the branding of "SNAIL" on the chainring, I didn't have huge expectations. But I've used the 32t red chainring with the cranks for a year on my townie commuter with a 7-speed rear and it's worked great. Less chain drops than the previous single front chainring which was presumably the stock Electra. The townie stretched frame requires a super long chain, if you have a similar cruiser it worked fine with this setup with a SRAM 7-speed chain. Wear seems normal and the install was simple on square taper bottom bracket.Seriously, the chainring says "SNAIL" right on it, how can you go wrong? The weird branding and the price were what sold me when I was browsing for it. ## Frequently Bought Together - BUCKLOS MTB Mountain Bike Single Speed Square Taper Crankset -170mm Cranksets Bicycle Crank Set with 104BCD 32/34/36/38/40/42T Round/Oval Chainring Fit for Ebike/Commuter Bike - BUCKLOS Bike Square Taper Bottom Bracket - 68/80/90/100/110/120x110.5 113 116 118 122.5 127 140 152 156 166 174mm Bicycle BSA Brackets for Mountain/MTB/Road/Fat Bike/Ebike --- ## 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.hr/products/240574315-mtb-mountain-bike-single-speed-square-taper-crankset-170mm-cranksets](https://www.desertcart.hr/products/240574315-mtb-mountain-bike-single-speed-square-taper-crankset-170mm-cranksets) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-07*
