The Schwalbe Tube No.2A is compatible with 14" tires with a width of 47-60 mm and is used in children's bikes, strollers, wheelbarrows, trailers, and more. Due to their excellent manufacturing, Schwalbe tubes have proven themselves in the market for years. They feature uniform wall thickness and a round shape. Their precise construction makes them durable at the seams. In a comparative test, the Schwalbe tube maintained air pressure significantly longer than other tubes (these lost almost twice as much air pressure as the Schwalbe tube within 30 days). A possible reason for this could be the lower butyl content in the other tubes. The special quality of Schwalbe tubes results from the uniqueness of their rubber compound. To ensure this high quality, each individual Schwalbe tube is inflated and tested for at least 24 hours before leaving the factory. **Features:** - Butyl rubber ensures double the air retention - 24-hour test for every tube - High elasticity allows coverage of many tire sizes per tube - Recycling process achieves a very good energy balance **Suitable for tire sizes:** - 47-254 14 x 1.75 - 47-254 14 x 1.90 - 50-254 14 x 2.00 - 54-254 14 x 2.10 - 57-254 14 x 2.25 - 60-254 14 x 2.35 **Valves:** - AV = Auto, Schrader (40 mm) - DV = Dunlop, Blitz, German valve (40 mm) - SV = Sclaverand, Presta, French valve (40 mm) **Delivery includes:** - 1 x Schwalbe Tube No.2A - Including valve
