Schwalbe switches rubber for thermoplastic in new light-weight tube

REICHSHOF, Germany - Schwalbe's new tube made of a thermoplastic polyurethane called Aerothan has achieved top values for elasticity, weight and puncture protection, all without the use of rubber. Available for road, mountain and trekking bikes, Schwalbe claims the Aerothan tubes are much more robust and durable than butyl, latex and other synthetic tubes and are completely recyclable.
