It’s been proven in wind tunnels that an aero helmet is the best investment you can make to shave seconds off of your next time trial. (Besides you know training really hard.) And this helmet has been tested on some of the greatest heads in the sport. Champions like Lance Armstrong Alberto Contador Levi Leipheimer Dave Zabriskie and David Millar have all raced in the Giro Advantage 2 for its performance fit and ventilation. We like it because it’s fast and sexy. (And you know if it’s good enough for Lance…)
