Stable air pressure. A Schwalbe tube simply holds air much longer. The quality of the ingredients and the purity of the rubber mixture determine the quality of the tube even at the material stage. During vulcanisation, every Schwalbe tube is placed in a mould and pumped up. This is the only way to ensure uniform wall thicknesses and excellent air retention.
Reliability. The consistent control ensures the highest possible functional reliability: Each tube is pumped up at the factory and stored under pressure for 32 hours to check for air retention.
Group tube system. Due to the high elasticity and quality, a single tube covers many tyre sizes. For example, hose number works.13 with tyre width 2.0 inch as good as with tyre width 2.5 inch. Only an extremely high-quality and reliable tube can meet this requirement.
