Schwalbe SV4 Inner Tubes are designed and manufactured to retain air pressure considerably longer than their competitors. Not only is each individual tube inflated and inserted into a mould to ensure that there is even wall thickness and excellent air retention, they are also stored under pressure for 24hrs to test air retention.
