Not sure where you got the idea they were track hubs.
The Classic Rendezvous page you referenced is a Photoshop job, not a real hub. Hi/Lo *REAR* road hubs did exist (IIRC,
Hi-E started the fad); Campy and Suzue made them for a couple years in the late 70s but people eventually lost interest in them.
