SCHWALBE Aerothan TPU Tube 29x2.4-3" with Presta Valve 40mm

This revolutionary, ultra-lightweight tube was jointly developed by Schwalbe and the German company BASF. It combines lightness with puncture resistance and significantly reduces rolling resistance, achieving performance superior to conventional butyl tubes. The tube is made of lightweight, heat- and friction-resistant thermoplastic polyurethane (TPU) material, and the resin valve is precisely welded using advanced, patented laser welding technology. The thermoplastic polyurethane perfectly fits the tire's internal carcass, reducing rolling resistance. Its excellent heat resistance makes it safe for downhill riding on rim brake bikes. Furthermore, compared to butyl tubes, depending on the size, it is more than 100 grams lighter, providing a dynamic and smooth ride. Available in a variety of sizes, from road bikes to mountain bikes and trekking bikes. Size: 29+ ETRTO: 62/75-622 Weight: 116g
