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:. Second generation ARC wheels are now built wider and feature even greater aerodynamics with a 62mm tall profile. Available in several distinct profile heights the Dicut 62 is a perfect middle ground for Aero TT and road racing. New redesigned rim shape offers lower drag and smoother airflow between tire and rim interface. The ARC1400 feature a new 240 Dicut Aero hub as well as DT`s classic Aero Comp spokes
