The Schwalbe Tube No.10 fits 24" tires with a width of 40-62 mm and is used in various applications including children's/youth bicycles, MTBs, BMX, trail, etc. Due to their excellent manufacturing, Schwalbe tubes have proven themselves in the market for years. They have a uniform wall thickness and are round in shape. Thanks to their precise construction, they are durable at the seams. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the others lost nearly twice as much air pressure in 30 days compared to the Schwalbe tube). A possible reason for this could be a lower butyl content in the other tubes. The exceptional quality of Schwalbe tubes comes from the uniqueness of their rubber compound. To ensure this high quality, each individual Schwalbe tube is inflated and checked for at least 24 hours before leaving the factory. Features: - Butyl rubber ensures double the air retention - 24-hour test for each tube - High elasticity allows for coverage of many tire sizes per tube - Recycling process achieves very good energy balance Suitable for the following tire sizes: 40-507 | 24 x 1.50 44-507 | 24 x 1.625 44-507 | 24 x 1.75 47-507 | 24 x 1.75 47-507 | 24 x 1.85 47-507 | 24 x 1.90 50-507 | 24 x 1.90 50-507 | 24 x 1.90 / 2.00 50-507 | 24 x 2.00 50-507 | 24 x 2.125 54-507 | 24 x 2.10 55-507 | 24 x 2.15 57-507 | 24 x 2.125 57-507 | 24 x 2.25 60-507 | 24 x 2.35 62-507 | 24 x 2.40 62-507 | 24 x 2.50 Valves: - AV = Auto, Schrader - DV = Dunlop, Blitz, German valve - SV = Sclaverand, Presta, French valve (40 mm) Delivery includes: - 1 x Schwalbe Tube No.10 with valve
