Aha! You thought I was talking about a cable with an integral lock. Not at all—haven't seen one of those that can't be overcome rather easily. I was thinking of a cable with end loops, and a heavy U lock, which is what I use. The cable keeps everything together. Around this neck of the woods, seeing orphan bike wheels securely locked to immovable objects is fairly common, as is seeing a securely locked bike with a missing wheel.
No lock is completely secure. The idea is to make it more trouble than the thief thinks it's worth.
