Best Chainring Bike Chain Guards in 2026

Most people settle for flimsy, round-link chains that offer nothing more than a false sense of security against determined thieves. The ABUS 12KS changes that dynamic by utilizing a unique squared link design that prevents burglary tools from gaining the necessary grip to cut through. This isn't just another heavy chain. It is a massive 1/2-inch thick hardened steel barrier requiring 10 tons of force to breach. I was particularly impressed by the inclusion of a nylon sleeve, which solves the common problem of heavy metal scratching up expensive motorcycles or ATVs. Whether you are securing an industrial container or a residential gate, the anti-corrosion coating ensures this remains a reliable deterrent in harsh outdoor environments for years.

After weeks of testing this heavy-duty setup on various outdoor equipment, the sheer build quality of the ABUS 6KS chain is immediately apparent. Unlike standard round chains that allow bolt cutters to get a firm bite, the unique squared link design makes it incredibly difficult for tools to gain the necessary grip for a clean cut. The 1/4-inch thick hardened steel is built to withstand massive force, yet the inclusion of a nylon sleeve is a thoughtful touch that prevents the metal from marring your motorcycle or ATV paint.
