Some while ago there was a guy on the forum stating the races on his Hyperons were shot and how to replace them. He posted a pic of the side of the hub shell with everything else removed. If you looked at it closely there seemed be residues of glue.
Later on he sent me a PM which also included a pic with all spokes removed (the FW). As it turned out what we initially thought to be glue was actually residue of "resin" that some greases leave as they dry up.
He managed to replace the races with some garage tools....
BTW, I've been running Bora Ultras on oil for more than five years now. They're still like new. I do maintain them regularly and properly.
Performancewise I doubt there would be any measurable difference between my set up and CULT bearings.
@Calnago: The cup and cone bearings of the wheels that use oversize axles are dimensionally identical to the industrial cartridge bearing type 6903 (17 x 30 x 7 mm). That's how I was able to use the CULT wheel bearing kit on a Miche Ti BB axle since that one uses the common 6903 as well.
Not all Campa wheels use cup and cone bearings though, just the ones that come with the OS axles, the others use run of the mill cartridge bearings.
All ISO BB use cartridge bearings, one 6903 on the NDS and two 6803s mounted as one on the DS for Record and Chorus for sure. The other ones I do not know.
Hope that clarifies it a bit.
