I need to slip 1.25" steel bar through the links** A: A little over a half of a inch in the links **Q: should I use only one chain to secure bike?Or one to secure the removable tire to the bike itself & one from bike to the street bike rack?** A: One chain. Loop through removable tire AND frame and around bike rack. **Q: What lock do you recommend to use with this chain to secure a bike in a neighborhood (Consider it suburbs, medium traffic area) ??** A: Any good thick shackle lock, not to thick, it has to be able to go through the chain links. I recommend a lock as stated above with a built in alarm. Happy Biking. **Q: What is the chain links thickness (I mean is it like For example 10mm so it’s hard for thieves to cut it ?** A: 9.5250 Millimeters = 3/8" I believe most thieves will look at this chain and go elsewhere, it is pretty intimidating. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very strong and seems secure. *by D***U on December 25, 2020* I bought this to secure the rear gate to my property. It is tougher than i thought and look forward to using it. The outer covering is thick and looks like it will last many years. going to cut it to make 2 chains for two locks on either side of gate. It think it will only be able to be cut by a grinder or cut off tool. Nice chain. wish it was 12 inches longer. ### ⭐⭐⭐⭐⭐ Great chain, great price *by A***R on February 22, 2020* Very substantial chain....very durable. Great product for the money. Would be thieves will think twice, before trying to cut this bad boy. Would defintly buy again should the occasion arise. ### ⭐⭐⭐⭐⭐ 3/8" hardened steel for a bargain *by E***. on February 9, 2015* The best protection you can get from a bike lock is either from a heavy duty U-Lock, or a hardened steel chain; and even then, if a thief really wanted your bike, he would be able to steal it. You want just enough of a nuisance that they'll move on to the next bike. After many days of research, I settled on this chain and an Abus 92/80 Solid Brass Monoblock. If you're looking for a 3 ft 3/8" hardened steel chain, this does its job at a fraction of the price compared to the Trimax chain, or any other competitors. I'm currently living around a "safe" area so I justified my purchase of this decent 3/8" chain. If your area is more prone to bike thefts, I suggest you get the Trimax or even a thicker Abus chain (also sold on Amazon). The canvas/nylon blend covering is actually pretty thick and should adequately protect your bike from any scratches. Three feet is barely enough to fasten my rear tire and frame, if you prefer more give, I suggest you lean towards the Trimax. The links are indeed square and are slightly yellow from a special zinc coating. The welds don't look perfect, compared to the product photo, but they're pretty decent for the price. The chain itself weighs about 4 pounds, luckily my chain and lock fits around my waist when I ride. --- ## 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/11324792-guard-security-968-heavy-duty-hardened-steel-square-link-bike](https://www.desertcart.tn/products/11324792-guard-security-968-heavy-duty-hardened-steel-square-link-bike) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-09*
