Technically the Shimano BB shouldn’t mate well with the Campy crank as they have different tapers but if it works then all is well I suppose.
I saw your red ‘84; that’s a beauty. I’m really excited to ride this one, which means I’ll probably cobble together a rideable build for now, and then ride it like that forever. We’ll see.
