An aero bike frame is a type of bicycle frame designed to minimize air resistance, making it more efficient for speed. These frames often feature a streamlined shape, with components that are integrated to reduce drag. They are commonly used in competitive cycling, especially in time trials and triathlons, where every second counts. The materials used in an aero bike frame are typically lightweight and strong, such as carbon fiber or aluminum. This combination allows for better performance without sacrificing durability. Many professional cyclists choose aero frames to enhance their racing capabilities and improve overall speed on the road.
