You're in college. If you should ever have IGH problems, it will be quite expensive to repair. If I were you, I'd just keep the Trek 1000 and make occasional upgrades when necessary. Try to find a bicycle co-op in your area. Just join the co-op. Invest in a few tools. Then do your own repairs and installments.

You'll be more thankful in the long run. Trust me!

PS.

Don't over invest in a bike that could very well get stolen on one of our college campuses...
