My Falcon produced Molteni Merckx has 126mm spacing. I bought this frame i n 1991--It was NOS. I first built it up around 1991 with Nuovo Record of v arying date codes the hubs being 1977 Record 126mm. I now have 1975 Super Record components on the bike. But, because I did not want to rebuild th e wheels when I did the component switch, I still have the 126mm 1977 hub s on the bike. So, I really have two questions. Would this frame have o riginally had 120mm or 126mm rear spacing and did Campy make a 126mm rear hub in 1975? Thanks in advance for the help.
