Cycling aerodynamics refers to the study of how air resistance affects a cyclist's performance. When a cyclist rides, they encounter drag, which slows them down. Factors such as body position, clothing, and bike design can significantly influence this drag. By optimizing these elements, cyclists can reduce air resistance and improve their speed. Key components of cycling aerodynamics include the aero bike frame, aero handlebars, and skin-tight cycling suits. These designs help streamline the cyclist's body and equipment, allowing them to cut through the air more efficiently. Understanding and applying these principles can lead to better performance in races and time trials.
