I have 2 very nice, and very fast Triathlon/Time Trial Bikes both with Dura Ace-10 speed
2004 Trek-TT (set-up for Ironman distance, with HED carbon bar, Zipp 404's, Dura Ace pedels, Selle San Marco Aspede triathlon gel seat)
2004 Cannondale Ironman-5000 (set-up for Olympic and 1/2 Ironman distance, Slice Aero frame, Profile Carbon Stryke bars, Zipp 404's, Dura Ace pedels, Cannondale Hollowgram SI cranks, Reynolds Ouzo Pro Aero fork, Selle San Marco Aspede triathlon gel seat)
** Both are set-up with Polar speed and cadance sensors to work with my Polar 720i
A new set of Zipp Z909's for the 2005 season should help
