A super thick, core hardened steel chain with a heavy, top quality lock is perhaps the most secure way to lock your bike. However these chains are so heavy and cumbersome, that they generally work best as a second, stationary lock which you leave wherever your bike is regularly secured for long periods of time.
Security that works is generally heavy, and often too heavy to carry on a bike. There are no easy answers to this problem. The best compromise is either a short length of chain such as the Protector 16mm, but even a 1.0 metre length of our 16mm chain weighs 4.5kg plus the weight of the lock.
