SCHWALBE Tubes Air PlusIdeally suitable for eBikes and cargo bikesAvailable for all common tyre sizes• Higher air retention: Due to the high percentage of pure butyl rubber, the Schwalbe Air Plus tube retains air significantly longer. Therefore less re-pumping is required• Higher puncture protection: Thanks to its approximately 70% higher wall thickness, the Schwalbe Air Plus is particularly robust - and thus offers above-average protection against cuts and punctures• Fully recyclable: Should the Schwalbe Air Plus ever need to be replaced - it is, like all other Schwalbe tubes, 100% recyclable.
