2 x Schwalbe Tyre Levers
Schwalbe Inner Tube special features
“Besides the quality of the ingredients, the purity of the rubber compound is decisive 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. Only 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 individually by visual inspection. The Schwalbe tube has been valued by German bicycle dealers for its high reliability for many years.
All valves are nickel-plated and threaded. The valve core is always replaceable.”
