Specialized Airlock Tube (Presta)

Specialized Airlock Tube (Presta)
Please select options


Specialized's Airlock Tubes are flat prevention at its finest. The non-separating sealant inside coats the tube for permanent protection that won't dry up. Should you ride through glass or over a piece of debris and put a hole in your tube, the sealant will seal it so you don't flat. Who knows? You may never get a flat again.

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).
