Handlebar components are essential parts of a bicycle's steering system. They include the handlebars themselves, which provide a grip for the rider, and the stem, which connects the handlebars to the bike's fork. Other components may include bar ends, which extend the grip area, and handlebar tape or grips for added comfort. Additionally, handlebar components can vary in design and material, affecting the bike's performance and rider comfort. Common materials include aluminum and carbon fiber, while designs can range from flat bars to drop bars, catering to different riding styles and preferences. Proper selection of these components can enhance the overall cycling experience.
