Fulcrum Racing 3/Campag Hubs
06 Oct 2014
Would you be able to advise as to whether Camapgnolo use 4mm or 5/32 (3.97mm) bearings in their hubs? From your experience would it make any difference if I were to use 5/32 and the originals were 4mm?

Any help would be appreciated.

I'm afraid that we have never sold Campagnolo hubs so we would not know what size bearings came as standard with them. I would however recommend keeping to the same size as even small changes in the size of the bearings could have a knock on affect of how well they work.
