Yesterday I took the flanges off an old Campagnolo Gran Sport 3-piece hub.
I expected to find the bearing surface machined into the barrels as in B-W 3-piece hubs, but instead I was surprised to find pressed-in bearing races in the barrel.
Does anyone know if all Campy 3-piece hubs have pressed in races or just the FB-made GS hubs?
