No chain which you can carry is a deterrent for thieves - Having had a lot of experience with Motorcycle theft, i use an Almax III chain, which is the toughest out there, but i doubt i could ride 500 meters with it.

Cables, chains and similar are a complete waste of time - double d-locking is the only secure method.
