I recently bought a new steel Bianchi as my first road bike, and I'm really enjoying it. I went to a guy who was very serious about measuring, and I'm busy trying to get used to the new position.
It seems to me that when I was riding my Gitane (I never claimed I wasn't a cliche) back in the 70s I was much more strapped on to a larger frame; it was a little scary, but I really felt like my whole body, or at least all of my legs, was (were?) involved in pedalling.
So I'm wondering if the theory of bike fit and bike build has changed over time. And, more to the point, if I follow through with my plan of picking up a vintage bike for the fun of it, do I try for the same measurements as my new Bianchi, or do I for that more stretched out feeling?
