In addition to the quality of the ingredients, the purity of the rubber compound is decisive for the quality of the tube. The base material is therefore pressed through a total of seven filters at enormous pressure before extrusion. All the tubes are placed in a mold and pumped up for vulcanization. Only this ensures uniform wall thicknesses and high air retention.
All finished tubes are inflated and thus stored for at least 24 hours to test them for air integrity. After that, each tube is carefully checked individually by visual inspection. From German bicycle dealers, the Schwalbe tube for many years, is aprecciated for its high reliability.
