The new Air Plus tube from Schwalbe is designed to hold air much longer than conventional bike tubes.
It is particularly suitable for bikes that carry higher loads, like e-Bikes, commuter bikes or cargo bikes.
The new Air Plus tube is made of special rubber with an increased wall thickness in order to retain air for longer. Naturally, the increased weight of the tubes limits its advantages for performance riding categories but that is not the intended use. The high air retention is particularly useful for riders of e-bikes and cargo bikes who are on the move with a higher bike weight. In these cases, the Air Plus tube retains air much longer and better protects against pinch and penetrating punctures. But riders of trekking and city bikes also benefit from carefree cycling with longer riding times and less maintenance.
“The new Air Plus tube contains pure butyl rubber, which has very low air permeability. This along with a wall thickness of 1.5 millimeters – approximately 70% more than a conventional bicycle tube – results in a 50% higher air retention depending on the tire size and air pressure,” explains Marcus Lambertz, Product Manager at Schwalbe. With normal use this means more time in between having to inflate the tube again. The increased wall thickness also protects against punctures caused by strikes and blows. With these advantages, the 120 grams that the Air Plus tube also weighs, should hardly be noticeable to riders. Schwalbe’s new Air Plus tubes are available in the seven most common sizes from 20 inches to 29 inches. They are 100% recyclable. Local availability to be confirmed.
