Mark asked:
"Hi, just a quick one. Campy Blue Box BB: What size loose bearings and how many? When did they go loose? Years? When did they use caged bearings? Years?"
14 bearings 3/16". The original bearings that came with the BB were in cages, but there is absolutely nothing that would prevent you from using loose balls.
>From 1974 to 1982, the axles were hollow female type. From 1982 to 1984, the axles were solid male type.
