OK, crawdaddio

Knowing what you do about bikes, locks and thieves and adding a tour rider's desire for lightweight equipment, what sort of rig would you suggest for someone on an extended tour. Let's assume their paranoia level is not extreme, but not too casual. Assume we're aware of the usual precautions like locking it to something permanent in a well-lit area with some foot traffic (grocery store, library, museum or some other tourist attraction)

A friend recently recommended an aluminum cable lock made by the American Lock Company. Any experience with the lock or the company?

This has been a good thread. It's something I've always thought about, but could never come up with a comfortable decision.

Thanks in advance
