This is all great input!
Cyccommute you have some valid points.
This got me looking at specs again. The Tiburon has a 700X42 tire and the Trek 7200FX has a 700X35 tire. Does this make a huge difference?
Again traveling on regular (potentially potholed) paved roads and unpaved roads, but no moutain climbing. I may experiment with an MTB at some point.
Thanks!
