Unlike anything that has come before it, the new Cyphon helmet blends classic Pro-tec styling with ground breaking technology. Built around an EPS liner that is injected directly onto an injection molded "macro" shell, the Cyphon represents a unique hybrid construction that combines the durability and impact resistance of a hard shell with the lightweight and low profile aesthetic of an in-mold micro shell helmet. As if this revolutionary construction was not enough, the Cyphon also comes equipped with the exclusive BOA® fit system, providing micro adjustment allowing riders to dial in the perfect fit. Buckle up, the rules just changed. SIZES: S/M | L | XL Certified to: CPSC 1203 / ASTM 1447 / CE 1078 (Standard Bike Certification)
