Campag ball bearings

[mattsccm]

you know that bit of string that needs its length sorting. Well...
I have a Campag Record front hub. Date ???? It does have a circlip over the port if that helps. Whilst in storage I have managed to lose a couple of the bearings. Any idea what size they might be? They are not the same as all the screw on rear hubs I have which are too big but this one needs to be bigger than the ones in front Campag hubs such as my old Tipo/GS ones.

Your average spoke length ruler also has ball bearing sizer holes.

If only I had one.
The best I can do is 5.5ish mm with the Vernier's

7/32

7/32" is correct.

BTW you should fit a new set; don't mix them up old and new, or side to side.

cheers
