I just picked up a 2008 Trek XO1 (picture is a 2009, but basically the same.
Trek Bikes | Bikes | Road | XO 1
I bought the bike because I race cyclocross in the fall/winter. I threw on some road tires, a 12-25 Dur-Ace cassette to replace the 12-27 105 cassette, and a 53 tooth 105 crank ring so I can use the bike for road racing. Soon I'll be getting all my official university gear from Hincapie Sports wear, which is sweat because its pro gear for cheap as shit. Cost me around 120 bucks a kit. Bought some bib knickers and a polar windtex jacket for the cold for damn cheap aswell.
