I'm interested in this bike, but the seller doesn't know the size and can't be bothered to measure it for me. This is just a potential project for fun, so I don't care if it is a great fit. I'm 6' 1" for reference. I have tried to use GIMP to measure the chainstay (which is the same for all sizes) then get a ratio to measure the TT and ST. Unfortunately, I can't get the measurements to work out. One problem is the distortion since the picture taken is not perpendicular to the plane of the bike frame. Based on the catalog and the way the bike looks, it must be a 58,60 or 63cm. The 60 and 63 both have a 580mm top tube. Any guesses on the size of this bike?
