Campagnolo Record threaded headset bearings
This is might be a bit of a stupid question but I've just bought a Campag threaded headset for my GF's frame. I've just taken it out of the box and checked all of the pieces and there don't seem to be any ball races.
Do these headsets simply not need them?
Am I supposed to buy them separately?
Or have I got a duff headset and I should return it?
