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. Ease of use - 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 = 55-58 cm.size L = 59-61 cm. The MIPS system means you lose 1 cm of head space compared with a classic RoadR 500 helmet. MIPS: The MIPS system consists of a layer with a low coefficient of friction, which allows for multidirectional movement of 10 to 15 mm during certain angled impacts. This movement aims to reduce the rotational force transmitted to the head.

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.
