A distinctive design with fewer and larger ventilation openings ensures optimal airflow and comfort on the longest and hottest bike rides. The Octal road bike helmet is optimized for a perfect balance between protection and performance. The helmet's EPS inner lining is thicker in areas where most impacts occur, providing better protection where riders need it most. A fully wrapped unibody shell increases the structural rigidity of the helmet, ensuring optimal strength at a low weight. The helmet is designed for protection without sacrificing weight and features a lightweight size adjustment system and adjustable chin straps that ensure a comfortable and secure fit.
