Schwalbe 622x18C-28C inner tube, schrader valve 40 mm
Schwalbe 622x18 - 28C inner tube
The inner tube is mainly made of butyl rubber . Butyl is a very elastic and airtight type of synthetic rubber. As with tires, additional admixtures are needed to create the rubber compound. The quality of the tube can vary significantly depending on the composition of the rubber. For example, Schwalbe tubes have extremely high air stability and flexibility. This high elasticity makes it possible to cover a wide range of different tire sizes .|
All valves are nickel-plated and threaded. The valve core is always replaceable. Schwalbe tubes with a classic cyclo valve can be pressure tested because they have a high-pressure valve core

Every Schwalbe tube is 100% recyclable. Recycled material can be used in production of new tubes without losing quality. We have developed a special devulcanization process in our factory and it has proven to be very successful for several years. Currently, each Schwalbe standard tube consists of 20% recycled old tubes

Taking into account all transport routes, the energy balance is positive. Only a fifth of the energy is used compared to the production of new butyl
