my friend had one of those cheap cable locks on his bike, and he had forgot the combo a while back... it took prolly 2-3 mins to nibble through the cable with a pair of 8 dollar cable cutters, but it took only 2-3 seconds to just snap one of the joints where the cable is attached to the combo part, with bare hands... dont ever trust those ****ty cable locks. once i had found that out, i was almost compelled to steal peoples bikes who had that kind of lock just based on principal, but i'd feel too bad, being a past victim of bike theft.
