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.   A tube covers many tire sizes through its high elasticity which 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, Schwalbe 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.   Inner tube: SV 17 Size: 700 x 28- 47c Valve: Presta Valve length: 40mm Weight: 150 Add to Wish List Tell a Friend Share Tweet
