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).

These tubes have smooth stems. If you have a Silca pump which relies on a rubber gasket with a compression seal, these will ensure that the gasket lasts a lot longer. As far as I can tell, they also work fine with other kinds of pumps as well.
