The Express Valve with a black cap is a versatile bicycle valve known for compatibility with multiple types of valve bodies, including Dunlop, Schrader (car), and Presta valves, though it does not work with slotted Dunlop valve bodies. This valve uses a two-seal system that helps prevent air leakage, ensuring better tire pressure retention. The black cap helps protect the valve from dust and debris, adding to its durability. It’s commonly found as part of universal valve sets, and its robust design is ideal for various biking needs​ Advanatges Inflate tyres effortlessly Excellent seal retention High quality, exceptionally long service life How does the express valve work? The rim nut holds the express valve securely in the valve body. The outer seal prevents the air compressed in the tyre from escaping between the express valve and thevalve body. The excess pressure in the bicycle tyre forces the nonreturn element into place. The fill opening of the express valve is closed securely.
