Special K,
You should see the special bikes that they use just for tri-athalons. I got to see one where I used to live, and WOW!
Yeah, it was like feather light, and looked like it was moulded to fit like an air-craft. They also had an interesting story in the British Columbia news yesterday how they designed Lance's suit that he uses for the tour-de-france.
They could not put a price on how much it cost them to develop it. The front had dimples like a golf ball, while the back of the suit was smooth, so as not to trap the air. They developed it at UBC. They also develop suits for other sports, such as rowers and other silly boring sports.
