Thanks for this site. It helped a lot. I am obviously in the 52/54 range as I expected. Actually even with the Caad10's more downward geometry its not that uncomfortable but I have been craving to buy a Cinelli and their geometry is way more upright. I tried Vigorelli at a bike shop 2 months ago. The bicycle was way heavier than mine but it was really comfortable and it was a smooth ride. My pocket says go for the 56 Vigorelli but my body needs 52 or 54. Thanks for the help. I think I wont buy another bicycle for at least 4 5 years, so it will worth it hopefully.
