Frame size suggestion
 

Currently I am riding 52 Caad10 Track. Because its track geometry I dont feel perfectly comfortable and I prefer more upright position. I also have been craving to buy a Cinelli and I found two good deals but with the sizes I have never ridden. I found Cinelli Vigorelli Steel frame set small size (50) and Vigorelli Aluminium large size (56). I can either buy one of these two or pay extra 250$ and buy size 54. What would you suggest?

My height is 1.73 and inseam 77cm.
Caad10 track (M) 76cm standover 51.4cm stack . 40cm reach
Vigorelli Alu (L) 81cm standover 56cm stack 40cm reach
Vigorelli Steel (S) 77cm standover 51.5cm stack 39cm reach

I'd suggest using this fit calculator as a starting point:

If you're actually after an upright position, though, the Vigorelli's probably not going to work out for you.

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.

Yeah, you right. I am going for the 52 probably. My bicycle shop doesn't have it at their stock right now. They had 54 2 months ago and it was pretty smooth ride. Hopefully they will have 52 in 3 weeks and I will buy that beauty. Thanks for the help.
