Bike Inner Tubes Schwalbe

A bicycle tube is predominantly made of Butyl rubber. Butyl is a very elastic and airtight synthetic rubber. But as with the tire other fillers are necessary to make up the rubber compound. The quality of a tube can vary significantly depending on the rubber compound. For instance Schwalbe tubes have extremely high air retention and elasticity. This high elasticity allows a wide range of different tire sizes to be covered. There is a difference between heat molded and autoclave tubes. Vulcanizing in a mold improves the uniformity of wall thickness thus reducing weight and improving air retention. For this reason the autoclave tubes which can be produced easier have become less common over …
