I have searched the forums and can't seem to grasp what I'm looking at/for.

In the bike porn thread there were two bikes posted that had wheel sets and hubs that I just loved. Here they are:





The bike I'd like to put them on is my 07 Bianchi Pista:


Can you guys tell me exactly what and where to buy either of these wheels sets that I could install onto my bike? From my searching it seems the red bike had to have a spacer on the rear to account for the lack of gears. So do I need to source the hubs and build the wheels as pieces or can I buy them as is?
Also was thinking of adding a pair of thick slick tires to either of these wheels sets; good idea or faux pas?
