Road bicycles are designed for speed and efficiency on paved surfaces. They typically feature lightweight frames, narrow tires, and drop handlebars, which allow riders to adopt an aerodynamic position. These bicycles are ideal for racing, long-distance rides, and commuting on smooth roads. The components of a road bicycle include gears, brakes, and wheels, all optimized for performance. Many road bikes use aluminum or carbon fiber for the frame to reduce weight. Riders often choose different gear ratios to match their riding style and terrain, making road bicycles versatile for various cycling activities.
