A tube is not just a tube.
- 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.
