Racing bicycles are specially designed for speed and performance on smooth surfaces. They typically feature a lightweight frame made from materials like aluminum or carbon fiber, which helps reduce overall weight. The tires are narrow and inflated to high pressure, allowing for less rolling resistance and better aerodynamics. These bicycles often come with drop handlebars, which enable riders to adopt a more aerodynamic position. Racing bicycles are commonly used in competitive events such as road races and time trials, where efficiency and speed are crucial for success. Popular brands include Trek, Specialized, and Giant.
