A tube isn't just a tube. Schwalbe tubes stand out with excellent airtightness, retaining air pressure much longer than others. The quality and purity of the rubber mixture directly impact the tube's performance. Each tube is individually inflated and molded, ensuring even wall thickness and top - notch air retention. With consistent quality control, these tubes offer reliable use. Each one is inflated at the factory and stored under pressure for 24 hours to test air retention. Our Group Tube System, thanks to high - elasticity and quality materials, covers a wide range of tire sizes. For instance, tube no.17 fits section widths from 28 mm to 47 mm. Marked'very good' by the Swiss consumer magazine 'Kassensturz' in 2012, Schwalbe tubes are test winners. In comparative tests, they retain pressure far better than other tubes, including well - known brands. The reason? Schwalbe uses high - quality butyl without compromise, even as prices rise. All tests were done on the same rim with the same 28” x 1.75” (47 - 622) tire, starting at 5 bar pressure and showing less loss after 30 days.
Using your Schwalbe tube is easy. First, make sure your tire and rim are clean and free of any debris. Then, carefully insert the tube into the tire, being gentle to avoid pinching it. Inflate the tube slowly to the recommended pressure, which you can find on the side of your tire. When it comes to maintenance, check the air pressure regularly. If the pressure drops too quickly, there might be a small puncture. You can patch a punctured tube using a standard tube repair kit. Also, store your tubes in a cool, dry place away from direct sunlight and sharp objects. This will help keep them in good condition for a long time.
