The Schwalbe Air Plus bicycle tube maintains air pressure for a longer time thanks to its increased wall thickness. As a result, you won’t need to inflate it as often. The high wall thickness also provides exceptional puncture protection. If the tube ever needs to be replaced, it is 100% recyclable. The Schwalbe Air Plus is particularly well-suited for high loads, making it ideal for e-bikes or cargo bikes. **Top Features** - Approximately 70% higher wall thickness - Keeps air pressure particularly well - Excellent puncture protection - High content of pure Butyl rubber - 100% recyclable - Weight: 270 g **Compatible with Tire Sizes** - ETRTO: 37-622 to 47-622 / 40-635 - Inch: 28 x 1.4 to 28 x 1.75 / 28 x 1 ½ - French: 700 x 35C to 700 x 45C / 700 x 38B **Valves:** - AV = Auto, Schrader - DV = Dunlop, Blitz, German valve - SV = Sclaverand, Presta, French valve **Delivery Contents:** - 1 x Schwalbe Air Plus bicycle tube 28 inch
