I got my Trek 2000 back near the end of July (1st road bike) and I'm very happy with it, but know I'm going to need to upgrade it at some point. I'm looking at upgrading to either the Trek Madone 3.1 or the Specialized Ruby Elite. I just haven't decided on which one yet and really can't afford either one at the moment. The only thing I worry about is that I'm very comfortable on the Trek 2000 even though it's a men's bike and I'm at the extreme low end of what will fit that bike. I am 5 ft tall.
