Here's a question for those who work at bike stores. My roommate has a Trek Fuel 90 with the Hayes Hydrolic disc brakes. He wants to get a new set of wheels that he wants to run 'road' tires on. Obviously this won't be 700c tires, but something as thin as possible.

Anyone have an approximate price for: Two new wheels, the brake discs and a new cassette? He doesn't need amazing wheels, since he'll be doing city riding with these and mountain biking with the others.
