Giro Selector Aero TT Bicycle Helmet
The Giro Selector Aero TT Bicycle Helmet is a helmet that works for you like no other helmet can when every split second counts. The foundation of aerodynamics is pure and unyielding; every bit of drag devours time and calories. And as speed increases, so does the air's appetite. Instead of simply facing this challenge head-on, the Selector™ gives you a new edge in the race of truth-the tail. By combining a smooth front profile with either of two different lower tails, riders can optimize their helmet for best aerodynamics based on their anatomy, riding position and even course conditions.
