In the race, top performance counts on every single stage, whether on a steep uphill climb or in the nerve-racking top speed of the sprint. The AirBreaker from ABUS supports you every kilometre of the way.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 as it is needed: maximum ventilation for slow, hilly stages, and optimum aerodynamics for fast, flat stages.
