Schwalbe inner tubes are inflated and stored for 24 hours to test for air retention. Afterwards, every tube is carefully checked individually by visual inspection. The Schwalbe tube has been valued by German bicycle dealers for its high reliability for many years.

Every Schwalbe tube is 100% recyclable. Without any loss of quality they can use recycled material in the production of new tubes. They 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.
