My F70 is also 3 years old. I've ridden 3 Pan-Mass Challenges on it. I like it very much. I have the smallest frame they made, with 650 wheels. No toe overlap. It has been crashed, and came out better off than me. It is quick and not a harsh ride like other Al frames I've ridden. The carbon seat stays and fork really work. Felt has made a very good line, and most of their frames have shorter top tubes than other brands so they tend to fit women well.
