My cyclo-cross bike.  It does double-duty as my commuter (with a different wheelset).  It is a
Cannondale CAAD-something....I can never keep track of their "different" aluminums.  Again
Zipp 404s but the rear wheel has a PowerTap hub....great for a 'cross workout because
afterwards you can see a detailed printout of exactly when you exploded and had to limp home.
