Not all tubes are created equal. Schwalbe tubes stand out with superior airtightness, holding 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 excellent air retention. With consistent quality control, you can trust these tubes. They're inflated at the factory and stored under pressure for 24 hours to test air retention. Our Group Tube System uses high - elasticity and quality materials, covering a wide range of tire sizes. For example, tube no.17 fits section widths from 28 mm to 47 mm. Schwalbe tubes are so reliable that they were marked'very good' by the Swiss consumer magazine 'Kassensturz' in a 2012 test. In comparative tests, Schwalbe tubes retained pressure far better than other tubes, including well - known brands. Over 30 days, other tubes lost nearly twice as much pressure as Schwalbe tubes, likely due to less or lower - quality butyl. Despite rising butyl prices, Schwalbe maintains high standards. All tests were done on the same rim with a 28” x 1.75” (47 - 622) tire, starting at 5 bar pressure.
Using your Schwalbe tube is easy. First, remove the old tube from your tire. Make sure the inside of the tire and the rim are clean and free of any sharp objects. Then, insert the new tube into the tire, being careful not to pinch it. Attach the valve to the rim hole and start inflating slowly. Don't over - inflate; follow the recommended pressure on your tire sidewall. When riding, keep an eye on the tire pressure regularly. If the pressure drops quickly, check for punctures. To maintain your tube, store it in a cool, dry place away from direct sunlight and chemicals. This will help keep the rubber in good condition and extend the tube's lifespan.
