The quality of the ingredients and the purity of the rubber compound is decisive for the quality of the tube. Before extrusion, the basic material is forced through a total of seven filters under enormous pressure. All tubes are inserted and inflated into a mold for the vulcanization process. Only this ensures an even wall thickness and high 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.
Group Tube System
The high elasticity and quality material used in Schwalbe tubes allows a great many tyre sizes to be covered. For example tube no. 17 fits section widths from 28 mm up to 47 mm. Only an extremely high-quality and reliable tube is up to this requirement.
