SCHWALBE Tubes Air Plus Ideally suitable for eBikes and cargo bikes Available 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.
