The Abus Ionus Chain Lock offers up mid duty mobile protection for your beloved ride. With 8mm thick, hardened steel chain links, it'll fend off hand tools with ease. In fact, just about the only option you'll leave bike thieves are power tools, so if you lock your steed somewhere conspicuous, it'll be safe while you're running errands. And to make sure there's no weak link, Abus employed a pick resistant barrel. So make sure you don't lose that spare key, because if you do, you'll have power tools in your future. And more than likely, some strange looks from passersby. The Abus Ionus Chain Lock is available in one size and in the color Black.
