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. Valve length of 40mm for standard version. Weight 145g
We use these tubes for installing Tannus puncture prevention inserts on Cargo Ebikes from Rad Power Bikes, Tern, Mycle and Benno Bikes.
