No. 16E. For bicycle tires in size 28″ inch (ETRTO 28/35-622). When it comes to road cycling with a tube, the Schwalbe Aerothan Tube Race is the first choice. It impresses with its low rolling resistance and dynamic, smooth riding dynamics. Compared to butyl tubes, a weight saving of 100 grams or more can be achieved for the entire bike. You can rely on the Aerothan Tube Race not only for excellent puncture protection, but also when riding downhill: it remains absolutely heat-resistant even after several emergency stops in quick succession with rim brakes. Aerothan tubes are made of 100% thermoplastic polyurethane (TPU) (including the valve) and are therefore fully recyclable. 28-622 28 x 1.10 700 x 28C 30-622 28 x 1.20 700 x 30C 32-622 28 x 1.25 700 x 32C 33-622 28 x 1.30 700 x 33C 34-622 28 x 1.30 700 x 34C 35-622 28 x 1.35 700 x 35C    Valve Type: SV  Valve length: 40 mm  Design: Aerothan  Type: TPU  Weight: 50 g  Product number: 10400423  EAN: 4026495814041
