Sounds like a great winter project building up a new bike. Maybe you should take one of those classes they offer at some of the LBSs. Then you could tinker with your own bike, or if all else fails buy a couple of books like I did and read and play. Nothing like being able to work on your own bike. My hubby just bought a Specialized Roubaix. Its a beauty, expensive, carbon, but alas, there is nothing to upgrade on it. For me, that's half the fun. I think Crystal sold her Cross-check, I don't see it in her listings. Check out her web-site though, she has great information.
