The headset on my 1976 Gran Sport is shot. It has three indexed positions--straight ahead, left, or right. The bearings are probably in races and replacing them with loose balls might help, but I think I will likely have to replace it.
But with what? When I posted photos earlier, the consensus seemed to be that the Campy headset probably wasn't original. The 1976 catalog on Mark Bulgier's site doesn't give a spec for the headset. I have a tendency to replace ailing headsets with cheap ones from Tange, and may do so here again. But still, it would be nice to know what I SHOULD be doing instead. Does anyone have any ideas?
