Round tube competition bikes are starting to be abandoned in favor of a fuselage that is more suitable for any situation in which a rider is racing against the clock. The wind is always against you, trying to slow you down. Triathletes and Time Trial Specialists today need an advantage against this element in order to win the major Ironman races and other Time Trials worldwide.
By using modern foil shapes, largely based on models created for air planes by the National Advisory Committee for Aeronautics(NACA), SCOTT engineers were able to design a structural performance that doesn't compromise on aerodynamics. Drag effects are highly optimized by a late flow separation on all tube sections and for fewer watts, riders can maintain the same average speed, keeping them fresh for whatever effort is most important.
