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 111 tires features 48 `vortex generators` which greatly reduce drag across the entire wheel system freeing up additional wattage. Aero wheels have Aero 111 26mm front tire and GP 5000 STR 28mm rear tire (Front & rear sold separately). Continental`s Black Chili compound and Vectran Puncture resistant technology. Wheel Features:. Second generation ARC wheels are now built wider and feature even greater aerodynamics with a 80mm tall profile. Available in 3 distinct profile heights the Dicut 80 is perfect for aero and time trial riding where aerodynamics are key. New redesigned rim shape offers lower drag and smoother airflow between tire and rim interface. The ARC1100 feature a new 180 Dicut Aero hubs as well as new Aero Lite II and Aero Comp II spokes for ultimate performance gains
