Aerodynamics

Aerodynamics describes the behavior of bodies in the wind and the resulting laws. In cycling, it is mainly the air resistance that is investigated, which counteracts the athlete’s movement. In a race, aerodynamics can be a decisive factor in victory or defeat, as air resistance has a significant influence on the speed of the cyclist.
You can positively influence the aerodynamics by making specific changes to the wheel and the athlete. For example, an optimized riding position, changing individual bike parts and clothing items, or simply rearranging one’s water bottle can lead to lower drag. The improved aerodynamics reduce the effort required, so the cyclist can ride at a faster pace with the same effort.

Especially in time trials as well as in triathlon, aerodynamics plays a major role. In competitive sports, position analysis and measurement (of the CdA) are therefore increasingly used. This value provides aerodynamic comparability. Special components such as carbon wheels (for example, from HUNT or ZIPP) are now “mandatory for professional athletes”. Socks, racing suits and helmets also play an increasing role and are sometimes specially adapted to the rider at the top of the world.

Riders like Alex Dowsett and Victor Campenaerts are also pioneers in terms of aerodynamics in road racing. Especially in breakaway groups it is important for a rider to pay attention to his energy reserves and to use them conservatively. When an aerodynamic riding position and the right equipment make it possible to save 15 or 20 watts over a period of hours or to gain numerous seconds of additional advantage, this can quickly make the difference between victory and defeat. Many riders therefore also use, in addition to their aero bikes and aero helmets, special socks and especially racing suits. These offer increasingly more comfort.
