From wooded trails to gravel roads. The Giro ELIXIR is the helmet for you if you're happiest when the mud crunches, pine needles rustle, and pine cones fly out from under your wheels. With 18 vents and a Roc Loc Sport clamping system that you can quickly tighten with one hand, its profile offers enhanced protection for the back of the neck. It also fits nicely on the head. Elixir - Show that you belong to the cycling tribe!
