Schwalbe SV7A - 20 X 1 1/8 - 1 3/8" - Presta

A tube is not just a tube.


Air tightness

  • Schwalbe tubes retain air pressure considerably longer.
  • The quality and the material purity of the rubber mixture directly effects the quality of the tube.
  • Each Schwalbe tube is individually inflated and inserted into a mold. This ensures the even wall thickness and excellent air retention.



  • Consistent quality control brings with it the security of use.
  • Each tube is inflated at the factory and stored under pressure for 24 hours in order to test the air retention.
