Schwalbe Inner Tube AV19
What Special Features Does A Schwalbe Tube Offer?
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 vulcanisation 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 bicycle dealers for its high reliability for many years.
A tube covers many tyre sizes through its high elasticity and quality, for example, tube no. 17 works with tyres from a width of 28 mm up to 47 mm - a great advantage for stock holding and at the same time, it is proof of the quality of the tube.
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 recycled material can be used in the production of new tubes. Schwalbe have developed a special devulcanisation 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.
