The SCHWALBE tube
Extreme air pressure stable! The rubber mixture makes it possible:
Less air loss and pump less often. Extremely reliable! Quality control for safe driving pleasure: Each SCHWALBE tube is checked twice at the factory for air retention.
A standard Schwalbe tube holds the air considerably longer. Due to the purity of the rubber compound. Due to the uniform wall thickness. More information is available here >>
Reduced weight. Same reliability as the standard version. Not in all sizes.
Extremely light. Only for very few sizes.
Extremely robust. A reinforced rubber base protects against dreaded valve shearing off. Only in Downhill sizes. If you want large volume with low weight, choose extra light.
