The HJC Ibex helmet is one of the high-end helmets designed by HJC that stands out for its aerodynamics and ventilation. Integra Venturi Dynamics technology to balance better wind resistance with optimal ventilation. Wind tunnel test: HJC is one of the few brands of helmets that has its own wind tunnel testing laboratory of the latest generation to test the aerodynamics, ventilation, noise and more determining factors in the development. By adapting the technologies developed in competitive motorcycling to high-end road cycling helmets, the HJC wind tunnel testing laboratory measures the constant force within the pedaling conditions. Venturi Dynamics: To achieve the maximum results in terms of ventilation, the Bernoulli principle has been adapted to the aerodynamic models. Through the pressure differences, cold air entering through the front opening drains through the rear openings dissipating the internal heat, which provides the cyclist with optimal ventilation.
