I have rode the 2012 trek 7.3 fx and the allegro sport. Another to consider in this range is the specialized sirrus.

I like the sirrus better than the trek and it was on par with the allegro sport. because of the disc breaks and poor roads in my area, I opted to get an allegro X sport. I liked the 7.3 but felt like the handlebars should have been h igher, I couldn't get a comfy position on it. The sirrus was love, but I've been off of a bike so long, I didn't like the skinny tire. The Allegro was the goldilocks bike for me.

Of course, this is me being 5'9 with longer torso than legs. Your fit will obviously vary.

*get my bike tomorrow, yay!*
