The Schwalbe Tube No.15 fits 28" (or 27" - 630) tires with a width of 18-28 mm and is used in racing bikes. Due to their excellent manufacturing, Schwalbe tubes have proven themselves in the market for years. They are uniform in wall thickness and round in shape. Their precise construction makes them durable at the seam. A comparative test showed that the Schwalbe tube maintains air pressure significantly longer than other tubes (the latter lost nearly twice as much air pressure as the Schwalbe tube within 30 days). A possible reason for this could be a lower butyl content in the other tubes. The unique quality of Schwalbe tubes results from the distinctiveness of their rubber compound. To ensure this high quality, each individual Schwalbe tube is inflated and tested for at least 24 hours before it leaves the factory. Features:

• Butyl rubber provides twice the air retention
• 24-hour test for each tube
• High elasticity allows coverage of many tire sizes per tube
• Recycling process achieves an excellent energy balance
