Schwalbe SV19 AE Aerothan TPU Tube

The new Aerothan tubes are more flexible and fit tyre widths from 1.75 to 2.6.

Schwalbe’s revolutionary Aerothan inner tube achieves unprecedented top marks for elasticity, weight and puncture resistance. Specifically designed for road bikes, MTBs and trekking bikes. Aerothan is a material that completely redefines the bicycle inner tube: extremely light, highly puncture-resistant and designed for minimal rolling resistance. Low rolling resistance on a par with tubeless tyres, 40 per cent lighter than Schwalbe Extralight inner tubes, all combined with enhanced puncture protection, heat resistance and approved for use with rim brakes.

Aerothan material

Aerothan Tubes are made from 100 per cent thermoplastic polyurethane (TPU), including the valve, and are therefore fully recyclable. Like all Schwalbe inner tubes, Aerothan Tubes can be returned to Schwalbe free of charge and easily via the inner tube recycling programme. The material from the used tubes is processed and subsequently reused as sealing or insulation material. In the heat resistance test, a starting temperature of 30 degrees is selected and the test is carried out at 78 km/h with 30 per cent braking force. In addition, the test determines how many emergency braking manoeuvres the tube can withstand. In the dynamic test, the Aerothan Tube emerges as the winner and is the only tube to withstand 7 emergency braking manoeuvres in a row. All Aerothan Tubes are approved for use with rim brakes. Aerothan Tubes do not burst suddenly. In the worst-case scenario, air loss occurs slowly and the bike generally remains controllable.

The Aerothan MTB tube is just as resistant to snakebites as it is to sidewall damage, thanks to the material’s extreme robustness. In cross-country and marathon riding, the surprisingly low weight and low rolling resistance really come into their own. Even on demanding trails, this tube never lets you down: because the Aerothan MTB tube remains extremely dimensionally stable even at low pressures, you always have reliable control over your bike.
