Make no compromises. Winners rely on the AirBreaker. In a race, maximum performance matters at 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 excellent aerodynamics while ensuring optimal ventilation. The Multi Speed design regulates ventilation according to the need: maximum ventilation during slow, hilly stages and optimal aerodynamics during fast, flat stages.
