If you like the aesthetic of fixed, and you want a road bike that oozes that aesthetic here's what you do. Find yourself a nice NJS track frame. Preferably a 3rensho, but any NJS track frame will do. Then cut off the track ends, and have vertical dropouts installed as well as derailure hangers, and shofter bosses on the down tube. Get a nice set of 36 spoke road wheels and replace the QR axles with solid axels. Quick release wheels spoil the aesthetic. Run a track stem and B123 bars. you're going to have to go brakeless with downtube shifters, because nothing ruins the fixed fgear aesthetic like having stuff on the handle bars. This setup will help you learn to ride fast if only to escape the irate U-lock weilding 3rensho fanboys.

or uh... You could just get something like the Bianchi Volpe and ditch the stupid sproingy seatpost.
