From the picture the top tube and fork looks like are columbus max, Do you have better pictures? the bike looks like racing geometry and stuff.
By the way the bike wont be light, columbus max bike weights a ton. But the ride is super nice. For the right price that bike is a nice keeper because is rare.
ps: the seatstays and downtube are max too... nice find man
, who knows who actually made the bike because the guy died in the 60's, same situation than with coppi bikes is only a name. Good bike anyways
