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.

Schwalbe is uncompromising in its standards – despite ever increasing world market prices of butyl.
