Technologies:


Air pressure stability
A Schwalbe hose keeps the air much longer. The quality of the ingredients and the purity of the rubber compound already determine the quality of the hose with the material. During vulcanization, each Schwalbe hose is placed in a mold and inflated. This is the only way to guarantee the even wall thickness and the excellent air retention.

reliability
The consistent control, which brings the highest possible functional reliability: Each hose is inflated in the factory and stored under pressure for 24 hours in order to check the air quality.

Group hose system
Due to its high elasticity and quality, a single tube covers a large number of tire sizes. For example, hose no. 17 with a tire width of 28 mm as good as with a tire width of 47 mm. Only an extremely high-quality and reliable hose can meet this requirement.
