Roadr 500 Road Cycling Helmet

Ventilation - The helmet's grille and inner channels facilitate continuous air flow. Lightweight - In-Mold helmet that is light but less compact than its big brother the 900. Easy dressing - new turn-ring system developed by our teams of engineers. Aerodynamics - Benefits from ventilation studies carried out on the Aerofit 900 helmet. Compatibility - compatible with our ViooClip lights. Anatomic design - Ponytail-compatible turn ring. Sizes: size M = 55-59 cm.size L = 59-62 cm.Weight: Size M = 275 g.Size L = 330 g.In-Mold moulding technology and EPS: The In-Mold moulding technology used in manufacturing this helmet makes it possible to mould the external polycarbonate shell during the expanded polystyrene (EPS) injection stage. This results in a structure that is much stiffer, very durable, and extremely light. The inner EPS structure absorbs the energy generated during an impact so that it is not transmitted to the skull, while the stiff external shell provides the helmet with longer-lasting durability.
