Weren't Superbe Pros those unusual kind of precision bearing where the
cone still screwed onto the axle? I think SunTour Cyclone hubs had
actual cartridge bearings as Sheldon describes, but the Superbe Pros
I've taken apart are not the same.

1992 was the last season of full production. In the 1992 book, Superbe Pro
and XC Pro are listed as using cartridge bearings "for the first time" but
the bearing size is not listed.
After removing the axle, just measure the bore and outer case with a caliper
if you cannot read the number on the seal.

If it is a cartridge bearing, then it's the SunTour standard 12x28x8
(ID, OD and width in mm).

But I'm certain most "sealed" Superbe Pro hubs used a precision
bearing whose inner race ("cone") was threaded directly onto the axle.
These are not cartridge bearings, though they have seals and precision
races reminiscent of cartridges. Of course I'm not talking about the
hubs from the seventies with ordinary cup 'n' cone bearings, nice as
they are.
