Trek Speed Concept preview

Trek Bicycles has borrowed a page from automotive aerodynamic design for its latest Speed Concept time trial machine, first seen under Alberto Contador (Astana) at last month's Critérium du Dauphiné Libéré and soon to be used by teammates Lance Armstrong and Levi Leipheimer as well for the Tour de France start in Monaco. Just as the sharply squared-off trailing edges reduce drag on high-performance vehicles – and high-mileage ones like the Toyota Prius – Trek says the unconventional shape will make its new Speed Concept the slipperiest machine on the road.
