I am currently riding an 05 Cannondale six13 R5000 Dura Ace as my daily commuter.
I have an On-One Dirty Disco cyclocross disc brake frame on order that I will build up to become my daily commuter, especially in the winter. Will be outfitting it with the following: Dura Ace 7900 compact, Avid BB7s, Chris King hubs and BB, DT Swiss TK 540 Disc wheels, Speedplay Light Action Ti pedals, Schwalbe Marathon Supreme tires, etc...
