Airtightness. 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.
Reliability. 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.
