A bicycle inner tube is usually made of butyl rubber. Butyl is a very elastic and at the same time airtight synthetic rubber. Just as with tires, however, other additives are necessary for the rubber compound. Significant differences in quality can result from the rubber compound used. Schwalbe inner tubes are extremely air-tight and elastic. Due to the high elasticity, a tube covers a wide range of different tire sizes.
