Just as with titanium and carpet fiber bikes over the past 30 years ago, racing bike frames have always been near the forefront of available technical developments. Aside from military aircraft, there are few other common applications that so profoundly benefit from the latest tubing technology and materials as do bikes. I recently read that briefly around 1890, before internal combustions engins became sufficiently powerfull and reliable, track racing bicycles actually held the world speed record as the fastest vehicle, definitly cutting edge tech for the day.
