Schwalbe tubes are designed and manufactured to retain air pressure considerably longer than their competitors


All tubes are inserted into a mould and inflated for vulcanization to ensure constant wall thickness and high air pressure retention.


Apart from the quality of the ingredients, the purity of the rubber mixture is crucial to the quality of the tube


The base material is therefore sieved at enormous pressure through seven filters before being extruded.


All tubes are inflated and stored for 24 hours in order to test for air pressure retention


Afterwards each, individual tube undergoes a careful visual inspection


This special quality control helps prevent unpleasant surprises


Only high elasticity and good quality allows a tube to cover very many tire sizes


Schwalbe inner tubes all have a very high butyl content and a high material purity.
