HED aero wheels only 2 ozs heavier than standard wheels...
Shimano 105 chainring and rear mech, Capreo freehub and cassette, Ultegra front mech (except on the model with the Mosquito bars which had a single chainring)...
Mosquito bars, Shimano Dura Ace downtube shifer (used as a thumb shifer), Cane Creek reverse action brake levers and a newly blackened stem...
Tapered forks, but not like the 1980s...
The fixed frame frame was not on show... all three demo bikes were separable...
