The Schwalbe Air Plus inner tube is an ideal choice for cyclists who want carefree cycling and want to pump less often. With its high proportion of pure butyl rubber, this inner tube retains air much longer than conventional inner tires, so you need to pump less often. What's more, Schwalbe Air Plus offers excellent leak protection thanks to a wall thickness increase of around 70%, making it very robust and well protected against leaks. What's more, this inner tube is 100% recyclable, just like all Schwalbe inner tubes.
