DT Swiss has engineered the ultimate aerodynamic combination of wheel and tire interface in collaboration with Continental with a joint tire: the Aero 111. Wheel and tire combinations pre-chosen and designed to be as aerodynamically efficient as possible. Tire Features:. Aero wheels have Aero 111 26mm front tire and GP 5000 STR 28mm rear tire (Front & rear sold separately). Aero 111 tires features 48 `vortex generators` which greatly reduce drag across the entire wheel system freeing up additional wattage. Continental`s Black Chili compound and Vectran Puncture resistant technology. Wheel Features:. Sophisticated ARC 1400 DICUT wheels represent the latest DNA of the 1400 level of DT Swiss and their aero partner Swiss Side. The Dicut 38 is the ideal climbing wheel for tackling those iconic long climbs while still benefitting from improved aerodynamics of the Arc 1400 series of wheels. Reduced wind sensitivity allows riders to maintain a stable aerodynamic position and full control of their bike. High-end DT Swiss aero spokes and the light 240 DICUT hub with its reliable Ratchet EXP system for more direct engagement complete this wheelsets
