Airtightness

The quality and purity of the rubber compound are crucial for ensuring the tube's airtightness. Before the extrusion process, the raw materials undergo rigorous filtration through seven filters under immense pressure. During the vulcanization process, all tubes are inflated and molded, ensuring uniform wall thickness and excellent air retention.

Reliability

Schwalbe maintains strict quality control to ensure reliability. Each tube is inflated at the factory and stored under pressure for 24 hours to verify its air retention capabilities, giving you peace of mind during your rides.

Group Tube System

Thanks to the high elasticity and premium materials used in Schwalbe tubes, a wide range of tire sizes can be accommodated. For instance, Tube No. 17 is suitable for tire widths ranging from 28 mm to 47 mm. This versatility reflects the commitment to providing a high-quality, dependable tube that meets various cycling needs.
