Specialized's Turbo Ultralight Tube is light to minimize rotating weight and compliant to provide a supple ride. The valve is only threaded on the bottom so you can secure it with the valve nut and inflate it safely as there are no threads to damage your pump's head, and the valve base is reinforced for excellent durability. Plus, this tube is dusted with talc for easy installation.
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).
