I have a Trek 2100 back from 1995, my first "real" road bike. Put many memorable miles on that thing, and then recently upgraded to a Trek 5200, which I absolutely love. The 2100 has been slated to trainer duties now .
Here's a generic pic of the 5200...mine is in nude carbon, which I LOVE:
I put Nasbar titanium pedals on it; they were relatively inexpensive at $130, but only weigh 240 grams, noticably lighter than my old Looks. I am also running a Ciclosport CM434 computer with cadence on the 5200.
