So you do need to be real careful.
Interesting, because according to Roberson's build list my early '80 GC should be a 58, but it's a 60, in serial number and actual measurement.
Note this one has short Campy rear dropouts, brazed on brake cable guides, no USA decals, and a shorter fork rake with a bend all the way to the dropouts.
I always assumed that Roberson snuck a 60 into a run of 58s, but now I'm thoroughly confused.
