Don't compromise. In cycling, the best rider with the best equipment wins. Winners rely on the AirBreaker. In the race, top performance counts on every single stage, no matter whether it's a steep ascent on a mountain or a nerve-racking high speed 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. Because the Multi Speed Design doses the ventilation just as it is needed: Maximum ventilation for slow, mountainous stages and optimum aerodynamics for fast, flat stages.
