Valve Information

Tubes are available with various valve types.
Choosing a valve is dependent on application and the rim's valve hole diameter.

Sclaverand-Valve (SV), French Valve
Outer Diameter:
6.5 mm
Good to know: The valve of all Schwalbe tubes with Presta valves can be unscrewed, e.g. for valve extensions or for filling with tyre sealant.

Technology:

Air Plus:
Schwalbe's Air Plus tubes hold the air much longer than other tubes due to their high proportion of pure butyl rubber, so that you need to re-pump less often.

Puncture Protection:
70% more wall thickness makes the Air Plus inner tubes exceptionally robust against punctures and snake bites.
