A helmet developed by professionals for professionals. Don't compromise. In road cycling, the best rider wins with the best equipment. Champions rely on the AirBreaker. In a race, peak performance counts on every single stage, whether it's the steep climb up a mountain or the nerve-wracking high speed of a sprint. The AirBreaker by ABUS supports you on every single kilometer. Thanks to the honeycomb structure of the innovative Multi Speed Design, the AirBreaker always provides the best possible aerodynamics while ensuring optimal ventilation. The Multi Speed Design regulates ventilation as needed: maximum ventilation during slow, hilly stages and optimal aerodynamics during fast, flat stages.
