Specialized's Standard Presta Tubes are lightweight, high quality, and available in a number of sizes; just the thing you need for a repair or a spare.
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).
