Schwalbe Bicycle Inner Tube Production Stages

  1. Before extrusion the basic material is pushed through 7 filters under incredible pressure
  2. All tubes are inserted & inflated into a mold for the Vulcanization process (this ensures an even wall thickess, & high Air Retention). 
  3. All tubes are inflated & stored for 24 hours to test for the quality of Air Retention. 
  4. After 24 hours each tube is carefully checked & visually inspected. 

The Schwalbe Inner Tube has been valued by the German Bicycle Dealers & Stockists for it's high reliability for many years. 

Schwalbe tubes cover many sizes due to it's high elasticity, all valves are Nickel-Plated, and Threaded &, the Valve Core is always replaceable. The classic bicycle valve comes with a high-pressure valve core, which can even be inspected for pressure. 

Schwalbe inner tubes are 10% recyclable, without any loss of quality Schwalbe can use 20% of recycled old tubes to produce new inner tubes. Schwalbe has it's own factory with a special devulcanization process, and has proven very sucessful for many years. The energy balance is positive, and used 1/5th of the energy in comparison with a production of new butyl.
