This talk about a Time Trial bike reminds me of the one I saw the other day at our favorite discount store (leftover from a large sale on bike stuff they had recently). It was so light I could pick it up with two fingers and gave me the sensation I have when I examine one of my large rubber powered model airplanes--it seemed to want to fly out of my hand. Price was $700+. Even though I could never contort myself properly to use it nevertheless I definitely had the urge to possess it.
