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