Hi p001!
I have the Trek 7200FX and I love it!
I've had it for about a month now and it has almost 300 miles on it and I haven't encountered any problems at all. Sorry but I can't really shouldn't answer any of the technical questions about the components because I'm kind of new to having a good bike from a LBS, instead of Wallyworld.
I use mine for commuting and long rides in the hills of southern Indiana on the weekends. And like you, I am starting to itch for a faster (and more expensive) bike...especially after reading through the
Under $700 Roadbike Thread. Felt F90...drool!
