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 bikes, MTBs, BMX, and trail bikes. Due to their excellent manufacturing quality, Schwalbe tubes have been reliable in the market for years. They have consistent wall thickness and are round in shape. Their precise construction makes the seams durable. 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). One possible reason for this might be a lower butyl content in the other tubes. The exceptional quality of Schwalbe tubes arises from the uniqueness of their rubber mixture. To ensure this high quality, each 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 Compatible with 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) Scope of delivery: - 1 x Schwalbe Tube No.10 including valve
