Wheelbuilding / Wheel Building / Wheel build help

Thanks for the answer,
You don't think that the white industries or phil wood are sealed bearings?
I know that the Campag is not, but I thought that on a more technically advanced hub it might be.

Possibly, I have no idea to be honest, I have not used them. Unless you are sentimentally attached to those brands or you like the logo, I don't think you can buy better track hubs than the Dura Ace though.
I wouldn't say that Phil hubs are technologically advanced either... white industries is a bit like the British Royce, although I think Cliff builds better hubs
