Tires can be a real drag. Not these.
Free speed where you least expect it: Game-changing tire design minimizes drag at tire-rim interface for measurable aerodynamic advantage.
Tubular tires leave a small indentation where the rim meets the rubber: Clincher tires fit inside the hook bead of the rim, creating a lip at the side of the tire. These lips and indentations disturb the airflow, causing turbulence and aerodynamic drag. Bontrager’s aero wings eliminate most of that space, thereby improving airflow and reducing drag compared to tubulars and standard clinchers.
