Keep rolling with Avenir's Threaded Presta Valve Tubes. They're built for durability and all Avenir tubes are inflated for 24 hours to ensure you get the perfect tube, every time.
Schrader valves are identical to those found on car tires. These valves are generally used on hybrid and children's bikes. Presta valves, which are found on most road and off-road bikes, are longer and thinner and feature a threaded tip, which must be opened to inflate (turn counterclockwise).
