Bontrager's Self-Sealing Thorn-Resistant tubes are the ultimate defense against flats. With a beefy 4.1mm thickness along the tread and sidewalls, these tubes scoff at the foreign materials on a mission ruin your day. And, if somehow a rogue thorn or piece of glass manages to penetrate the defenses, these tubes pack a sealant inside that instantly seals small hole punctures.

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).
