TGR For some of us the rickety edifice of our 'personality' is built entirely out of things it is anywhere between ten seconds and ten thousand years too late to be complaining about! I will resist careening unfathomably off topic and boring us all with the 'torqueless grumbling timeline'..
I cannot fault your analysis. In response to your question, I would say that yes... if it says 'pista' it is a track hub...or at least marketed as such. To me that is a fancy way of saying: 'single-speed hub with optimally placed flanges equidistant from the centre', which is at least a good start towards a nice hub.
David B, If Campag had such a policy, surely it dates from a fairly recent time in which 'road' hubs were equipped with something more than a dustcap to keep the elements out? AFAIK a '70s cup'n'cone 'road' hub was no more sophisticated than its 'track' variant in this regard?
You mention a 'single-speed cousin intended for the road too', but where is this hub? I'm not saying it doesn't exist.. If it does I would like to know about it. This possibly reinforces my point that single-speed hubs are called 'track' or 'pista' by convention only, and if I ask for a single-speed hub with equidistant flanges, someone will say: 'Oh, you mean a track hub?', and charge me a premium for it into the bargain.. as if riding on the road without desiring to change gear made you into some sort of subversive nutter...
