Why Choose a Schwalbe Inner Tube?

The Schwalbe tube has been valued by German bicycle dealers for its high reliability for many years.

Its not just the quality of the materials used but the purity of the rubber compound that is decisive in making a quality tube.

Before the extrusion process, the basic material is forced through a total of seven filters under enormous pressure. All tubes are inserted and inflated into a mold for the vulcanization process. Only this process ensures an even wall thickness and high air retention.

All tubes are inflated and stored for 24 hours to test for air retention. Every tube is then carefully checked by visual inspection.

All valves are nickel-plated and threaded. The valve core is always replaceable. Also, Schwalbe tubes with a classic bicycle valve can be inspected for pressure as they have a high-pressure valve core.

Every Schwalbe tube is 100% recyclable. Without any loss of quality Schwalbe can use recycled material in the production of new tubes. Schwalbe have developed in their own factory a special devulcanization process and for several years, it has proved very successful. Right now every Schwalbe standard tube is made up of 20% recycled old tubes.

Taking into account all transport routes, the energy balance is positive. Just a fifth of the energy is used in comparison with the production of new butyl.
