I have a Trek 3500 that I need to lock up when I ride city trails, but I have been nervous as both of the wheels are incredibly easy to remove (flip a switch, rotate a lever a few times and they detach in seconds.)
I purchased a cable lock assuming it would be sufficient, but the more I read here about how easy cable locks are to remove I'm getting a little nervous as bike theft is a pretty big problem in my area.
Is a combination of a cable and a U-Lock the best? I purchased a decent (but not high end) cable lock, and I reviewed most of the suggestions for locks found in Best bike lock and the other threads. However the cost of a combination of these locks is around $120+.
In the end, its not the money (as having to buy a new bike obviously wouldn't be good), but is it worth it to invest so much into a combination of lock systems?
