A "spoke" is a rod or bar that connects the center of a wheel, known as the hub, to its outer edge, called the rim. Spokes are commonly found in various types of wheels, including those on bicycles and cars. They help distribute weight and provide structural support, allowing the wheel to maintain its shape and function effectively. In a bicycle wheel, spokes are typically made of metal and can vary in number, usually ranging from 24 to 36. The arrangement and tension of the spokes are crucial for the wheel's performance, affecting its strength, stability, and overall ride quality. Properly maintained spokes contribute to a smoother and safer cycling experience.
