Looking for info on the type of forks used on Cinelli Supercorsa frames from the late 1950s. Specifically length of blades and rake. Are these similar to the forks used in the mid-1960s? I know that shortly after 1965, the blades became about 1 cm shorter. And then, in the early 1970s, holes appeared in the reinforcing triangles brazed on the inside tops of the blades.
Anybody got a spare fork for such a bike? I have a late 1960s one to swap... (the fork on my 1957? project frame must have been replaced at some point with a later model - comparing to a 1965 Supercorsa shows 1 cm shorter blades!)
Also, what rear spacing was used back then?
Any help is appreciated.
