Road bike helmets

Aerodynamics and ventilation are two key elements in the development of the MACH 4 helmet. Ideal for triathlon and road cycling, it is designed for year-round use in all weather conditions. The helmet shell, which is almost completely closed, promotes aerodynamics; however, thanks to the front openings and the circuit of internal air channels, the MACH 4 maintains and ensures excellent ventilation. • 7 ventilation holes • Roll-Fit with vertical micrometric adjustment • removable and washable interior • mosquito net • reflective back part • Fidlock® magnetic buckle Sizes: M (53-58 cm), L (59-63 cm) Certificates: CE EN 1078, CPSC
