I got another bike for commuting to school and I am wondering how best to protect it at school. I am going to try to lock it inside but not sure if that will be possible. I know I can use a U lock to lock both wheels to something, but I'm not big on having to remove the front wheel all the time and having the fork banging around in the ground. I am considering getting a cable lock to keep in my bag to lock the front wheel up and using the U lock on the rear. I would leave the U lock on the rack, that way I don't have to carry it around but ill have the cable lock on me at all times if I have to lock up somewhere different.

Sound like a good plan? Any recommendations for a relatively thin/light cable lock long enough to get both wheels?

Thanks!
