Giro Selector Bike Helmet

Triathlons and time trials just got faster thanks to the Giro Selector aero bike helmet, which offers tailorable aerodynamics so you can achieve new PRs. Unique design allows helmet to be modified to optimize aerodynamics based on the rider, riding position and even course conditions. Comes with 2 tails, 10mm or 45mm, allowing you to tailor helmet to your aero position, be it a relatively flat back profile or a more compact position or hunched profile. In-mold technology bonds the helmet's tough outer microshell to the impact-absorbing expanded polystyrene liner, creating a light, cool and strong helmet. Roc Loc TT fit system offers a quick, self-adjusting fit for hassle-free comfort. X-static(R) padding quickly wicks moisture away from head and boasts antimicrobial properties to combat odor development. Vented, removable eye shield aligns with internal ventilation channels that help move cool fresh air in and across the head, and then move the hot air out.
