Your head needs protection when you’re on the bike, but you want a helmet that improves your time as much as possible, right? The Louis Garneau Vorttice Black Knight Helmet has dimpled technology on the front of the helmet to keep air flow close and what they call a ”Vortex Generator” at the top, so that the flowing air gets accelerated and can glide along to the end of the helmet and eliminate air disturbances. Go fast, keep your head cool and the precious contents inside your head safe.
