SCHWALBE AEROTHAN 29x2.40/3.00 Presta 40 mm inner tube 10461173

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

It's made from a thermoplastic polyester-polyurethane called Aerothane, more robust and resistant than those made from butyl, latex or other plastics. It offers unique tensile strength, exceptional cushioning, resistance to extreme heat (temperatures in excess of 150°C at 78km/h) and maximum wear, and is recyclable.

Aerothan chambers don't burst suddenly, but air escapes slowly in the event of a fault. Even with extremely low air pressure, they retain their shape and handling is stable. Also, assembly is now much easier: the chamber doesn't slip and can't jam. Finally, save at least 100 g per inner tube compared with conventional models!
