Does anyone know what EXACTLY this lock is? I found it on sale a at a local locksmiths. It's cheap, it's Abus and it's been sitting in their window for a while. I think it's an old CityChain, but I don't know the Abus rating or just how old it is. The guy at the shop has no idea. Thanks.
If you run a search on "Google", you may find the same lock in Abus listings in Europe. From the photo alone, it does not look like one of their heavy weight chains. In tests of locks, the only chains that "beat" a good U-lock for security are the super heavy six pound and eight pound chains. And, the best three pound U-locks are so good (such as the OnGuard Brute Mini), that most folks don't need an eight pound chain.
