Schwalbe SV21Air inner tube

The new Air inner tube from Bohle is ideal for e-bikes and cargo bikes.

Thanks to its high proportion of pure butyl rubber, the Schwalbe Air Plus inner tube retains air significantly longer. This means it needs to be re-inflated less often. With a wall thickness around 70 per cent greater, the Schwalbe Air Plus is particularly robust – and thus offers above-average protection against punctures and blow-outs.

All finished inner tubes are inflated after production and stored for at least 24 hours to test their air retention. Afterwards, each inner tube is carefully inspected individually by Schwalbe.
