A helmet developed by professionals for professionals. Make no compromises. In cycling, the best rider with the best equipment wins. Winners rely on the AirBreaker. In a race, top performance counts on every single stage, whether on a steep climb or at the nerve-wracking top speed of a sprint. The AirBreaker from ABUS supports you on every single kilometre. Thanks to the honeycomb structure of the innovative Multi Speed Design, the AirBreaker always offers the best possible aerodynamics and at the same time ensures optimum ventilation. This is because the Multi Speed Design doses the ventilation just as it is needed: maximum ventilation on slow, hilly stages and optimum aerodynamics on fast, flat stages.
