The Schwalbe Tube No. 2 fits 14" and 16" tires with a width of 32-44 mm and is used in children's bicycles, strollers, wheelbarrows, trailers, etc. Thanks to their excellent manufacturing, Schwalbe tubes have proven themselves on the market for years. They have a consistent wall thickness and are round in operation. Due to their precise assembly, they are durable at the seams. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost almost twice as much air pressure as the Schwalbe tube in 30 days). A possible reason for this could be a lower butyl content in the other tubes. The exceptional quality of the Schwalbe tubes results from the uniqueness of their rubber mixture. 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 coverage of many tire sizes per tube - Recycling process achieves a very good energy balance **Suitable for tire sizes:** 40-279 | 14 x 1 1/2 | 350 x 38B 37-288 | 14 x 1 3/8 | 350 x 35A 37-288 | 14 x 1 5/8 x 1 3/8 40-288 | 14 x 1 5/8 | 350 x 38A 44-288 | 14 x 1 5/8 | 350 x 42A 44-288 | 14 x 1 5/8 x 1 3/8 | 350 x 42A 47-288 | 14 x 1.75 47-288 | 14 x 1.90 32-298 | 14 x 1 1/4 | 350 x 32A 37-298 | 14 x 1 3/8 40-305 | 16 x 1.50 **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 2 including valve
