Hi

Just about to renovate some old vintage Campag hubs from the early 1980 one pair Gran Sport and the others Record.

Does anyone know the Ball Bearing size for these and would grade 20 Bearings be good enough ?

Thanks in advance

Dave

The #20 bearings would be good enough but I suspect knowing Campy they were better originally. The simplest way to know the size is to take the hub apart which you need to do to replace the bearings anyway. Roger
