Not all tubes are the same.
Air pressure stability
A Schwalbe tube holds the air much longer. The quality of the ingredients and the purity of the rubber compound determine the quality of the tube already at the material stage. During vulcanization, each Schwalbe tube is placed in a mold and inflated. This is the only way to ensure uniform wall thickness and excellent air retention.
The consistent control that provides the highest possible functional safety: Each tube is pumped up at the factory and stored under pressure for 32 hours to check its air content.
Group Tube System
Due to its high elasticity and quality, a single tube covers a large number of tyre sizes. For example, tube no. 17 works as well for a tyre width of 28 mm as for a tyre width of 47 mm. Only an extremely high-quality and reliable tube can meet this requirement.
