Aw man, that is bad news re the Marinoni. It is the one I was leaning towards. I am about 5'10, so think I need something in the range of 56cm to 58cm? I haven't had a fitting yet at my LBS...
I am going to contact the seller again today of the Marinoni and double check his measurements.
As someone who doesn't really know vintage bikes, can you say anything about the components on either one??
