Schwalbe use the highest quality ingredients in the manufacture of their inner tubes, the purity of the rubber compound is critical for the quality of the tube. Before extrusion, the basic material is forced through a total of seven filters under enormous pressure. All tubes are inserted and inflated into a mould for the vulcanization process. This ensures an even wall thickness and high air retention . All tubes are inflated and stored for 24 hours to test for air retention. Afterwards, every tube is carefully checked
