At the start of this summer I bought a nice Fuji Roubaix, and have been riding it constantly. As this next year begins, I'm planning on using it to make the 6 mile commute to campus from my apartment instead of bothering to drive such a short distance. I'm wondering what you guys would suggest for security.
When I have it at my apartment, I plan on taking it into my room and, if there's going to be a lot of people in the apartment, locking it up in there. On campus it will likely be left on the rack where I work, as most of my classes happen nearby there, and it is out of the way of much foot traffic so I'm not too concerned about the security there (I work in transit, and I've seen many bikes that were left on buses just left on the racks without a lock for months at a time).
If I do take it to a different rack, it won't be in any one place for too long. I have one of those Bulldog Mini U-Locks, which seem like they'll work great if I can figure out a way to carry it. I had been carrying it in my bag, but I recently saw a picture of somebody who carried it by running the U part under their seat bars and letting it hang there for the ride. It seems to me like that could damage the seat but... thoughts?
I know I need to get the locks to replace the quick release levers on my wheels and seat, and I've already talked to my LBS owner about that. Any other recommendations?
