The gold-medal-contending Aussies will ride a new bike design at the Olympics, the BT Blade. It weighs just 6.8 kilograms (15 lb.), and the manufacturer's standard single-piece, carbon-fiber frame has been modified by aerospace firm Nezkot Engineering for maximum aerodynamic efficiency. The price tag might deter even die-hard amateur cyclists, though it is available for sale in this Olympic format.
