SCHWALBE AEROTHAN 700x37/50 Presta Inner Tube

The SCHWALBE Aerothan inner tube is a revolutionary model that achieves superior values in terms of elasticity, weight, and puncture resistance.

It is made from thermoplastic polyester-polyurethane called Aerothane, which is more robust and resistant than butyl, latex, or other plastic tubes. It provides unique tensile strength, exceptional damping, extreme heat resistance (temperatures above 150°C at 78 km/h) at maximum wear, and is also recyclable.

Aerothan tubes do not burst suddenly — instead, air escapes slowly in the event of a failure. Even at extremely low air pressure, they retain their shape and handling remains stable. Also, fitting is now much easier: the tube does not slip and cannot get pinched. Finally, save at least 100 g per inner tube compared to conventional models!
