Got a close out "Martec" monocoque carbon frame and FULL carbon fork for around $400 (the same thing as the BP Stealth 'cept it's yellow, very yellow).

Bulit it up with Ultegra/105 mix plus a Dura Ace crank I already had.

Slapped on my Renn disc and Hed Alps (ft) along with a few other parts I had lying around and Presto!!! I have a fast, cheap, aero bike.
