Guys...
I bought it used from a friend of my wifes son..needed money for college type thing...My wife agreed in to the purchase really before I could say much...
The frame is a 55cm... I am 5-10 1/2.. with a 30" inseem.. my arm are not the longest either.. and I am fat.
I think I should be on a 53.. but this one does fine. I ride for 1 to 2 hours 3-4x a week and I do fine.. So far i have lost 40lbs..with another 30lbs to go. Once I do that I will be looking at a new bike.
