A bicycle wheel spoke is a slender rod that connects the hub of a bicycle wheel to the rim. The spokes are responsible for supporting the weight of the rider and any additional load that is placed on the bike, such as baggage. They also transfer torque from the hub to the rim, which allows the bike to accelerate and brake. Spokes can be made of various materials, including steel, aluminum, and carbon fiber, and they come in different lengths and thicknesses to suit different types of bikes and riding conditions.
