TrackSpec hubs.
 

Does anyone know anything about TrackSpec High Flange Aluminum hubs, or particularly the whole wheel that usually accompanies them? The rims are 36H Aluminum Aero Section Track DoubleWall.

And does anyone have an opinion about them in regards to use on roads?

I don't believe trackSpeck is a brand name. I'm assuming you are seeing this on a website and they are trying to say that it is a "track specific" hub. Who the heck knows about what rim it has, if it's not named it's probably nothing to write home about.
