Lance Armstrong was an early and ardent adopter of carbon fiber. In 2005, he jumped from racing an aerodynamic Trek Madone to the new Trek SSLX. Outfitted with boron-infused carbon fiber for extra stiffness and with grams of weight drilled from nearly every metal surface, this 15.4 lbs machine remains one of the lightest ever raced in the Tour de France.

Here, Froome races the Pinarello Bolide, a time trial bike with an aerodynamic, fully integrated front end, and hidden brakes.
