Do not compromise. In bike racing, the best rider with the best equipment wins. Winners rely on the AirBreaker. In the race, top performance counts on every single stage, whether it's the steep climb up the mountain or the nerve-wracking top speed of the sprint. The AirBreaker from ABUS supports you in this on every single kilometer. Through the honeycomb structure of the innovative Multi Speed Design, the AirBreaker always provides the best possible aerodynamics and at the same time ensures optimal ventilation. Because the Multi Speed Design doses the ventilation as it is needed: Maximum ventilation on slow, mountainous stages and optimum aerodynamics on fast, flat stages.
