Bontrager's Race XXX Tubes are perfect for race day and fast training. They reduce rolling resistance and rotational weight for quicker acceleration and more speed. You want a pro trick? Add a touch of corn starch or talc to the tire for an even better ride.
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).
