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. Endurance wheelsets have Aero 111 29mm front tire and GP 5000 STR 30mm rear tire (Front & rear sold separately). Continental`s Black Chili compound and Vectran Puncture resistant technology. Wheel Features:. ERC 1100 Dicut 45 wheelsets with a mid-height carbon rim are well rounded for all road disciplines. Latest generation aerodynamically optimized T-head Aerolite and Aero Comp spokes for lower rotational and translational drag. Redesigned rim shape has been optimised for improved crosswind stability and aerodynamic drag. 22mm inner rim width supports modern wider tires for increased comfort and stability. Patented T-head flanges ensure perfect aerodynamic alignment of spokes. New aero 180 Dicut hubs with low-friction SINC ceramic bearings
