The Tour de France pedals off on Saturday and the Seattle Times reveals that Lance Armstrong’s entourage descended on the wind tunnel at the University of Washington this past December to test out equipment. Typically host to Boeing aircraft, the tunnel this time blew past Nike’s Swift Spin Suit, a Trek bicycle, and Giro helmet. Improvements to the braking system and handlebars were made and Nike enhanced their special mesh suit. Over on the other coast, the Cervélo team used a wind tunnel at MIT to improve the aerodynamics and usage of their time trial bikes.
