As a bicycle moves, the rider feels air resistance, which affects speed and the rider's energy expenditure. In cycling races, where the main focus is on increasing speed, modifications to the design of the bike, optimization of the bike's materials, and adjustments to the riding position are often utilized to increase speed and reduce energy expenditure. These optimizations are based on aerodynamic principles, which is one of the practical applications of aerodynamic developments. Therefore, the influence of aerodynamics is becoming more and more important in today's bicycle racing. In this paper, the application of aerodynamics in cycling is studied and analyzed through theoretical analysis and literature review. Based on the experimental study of aerodynamics, the optimization of various parts of the bicycle is analyzed to give riders the advantage and help them to increase their speed. Provides the reader with an initial understanding of the application of aerodynamics in cycling.
