Hi, I'm another bike Nazi from Portland, OR.
No, just kidding.
I'm a high school senior here in Portland and ride my back too and from school. Thus, I've had two bikes stolen in my relatively short life Stupid cable locks. Never leave your bike locked with a cable, even for an hour. But you probably knew that. I also cycle to cross-train for running--biking is more fun than running, I have to admit.
I'm currently on the market for a new bike, and have been looking at cyclocross bikes because it would be possible to do some trail riding, keeping things interesting, you know. But I don't have much money, so we'll see.
Anyways, this looks like a useful place, and you'll probably see me in the mechanics section a lot asking stupid questions about truing wheels and the like.
