Super Record hubs are exceedingly rare. They have titanium axles. I've seen SR BBs (both early hollow and late solid), pedals, early two bolt SR seatpost and of course hundreds of the brakes and derailleurs but never any confirmed or even purported Ti axle hubs.
They are listed in Catalog 17 (basically Campy for the 70s) but it is possible they never made any!
Any confirmed UHO (Unidentified Hub Object) sightings out there?
