Bicycle valves are essential components that allow air to be pumped into and maintained within a bicycle tire. The two most common types are the Schrader valve, similar to those found on car tires, and the Presta valve, which is narrower and often used on higher-end bikes. Each type requires a specific pump or adapter for inflation. Proper maintenance of bicycle valves is crucial for optimal tire performance. A damaged or leaking valve can lead to air loss, affecting ride quality and safety. Regularly checking the valves for wear and ensuring they are securely closed can help prevent issues while cycling.
