Schwalbe SV5 Inner Tube 18 inch

Germany's Best-Selling Bicycle Inner Tubes, Reliable and Reassuring: Bicycle dealers will appreciate its reliable quality. Each inner tube is inflated and tested for leaks for 24 hours in the factory. Longer-lasting air pressure retention: We ensure the use of high-content butyl rubber and high-purity materials to manufacture the inner tubes. Therefore, Schwalbe inner tubes can maintain air pressure longer compared to other brands. 100% Recyclable: We've developed our own desulphurization process in our factory. This allows us to use recycled butyl rubber in producing new tubes without compromising on quality.
