Valve Information

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

Schrader Valve:
- Synonyms: Auto Valve (AV)
- Outer Diameter: 8.5 mm

Presta Valve:
- Synonyms: Sclaverand-Valve (SV), French Valve
- Outer Diameter: 6.5 mm
- Other: All Schwalbe tubes with a Presta valve can be unscrewed. (To lengthen the valve, add anti-flat agents, etc.)


The quality of the ingredients and the purity of the rubber compound is decisive for the quality of the tube. Before extrusion, the basic material is forced through a total of seven filters under enormous pressure. All tubes are inserted and inflated into a mold for the vulcanization process. Only this ensures an even wall thickness and high air retention.

Consistent quality control brings with it the security of use: each tube is inflated at the factory and stored under pressure for 24 hours in order to test the air retention.

Group Tube System
The high elasticity and quality material used in Schwalbe tubes allows a great many tyre sizes to be covered. For example tube no. 17 fits section widths from 28 mm up to 47 mm. Only an extremely high-quality and reliable tube is up to this requirement.

Die Schläuche waren/sind für das Rad meines fünf-jährigen Sohnes. In seinem Alter achtet man für mich augenscheinlich nicht darauf, wo man 'rüber fährt. Vielleicht hat er nur Glück, vielleicht sind es die Schläuche, aber er hatte seit einem Jahr keinen "Platten" (Straße, aber auch leichtes Gelände) .
Ich selbst bin schon lange und immer noch Fan von Schwalbe-Schläuchen, auch wenn ich mittlerweile Tubeless fahre.

Für GhettoTubeless auf 26 Zoll, funktioniert sensationell mit Syntace W35 und Maxis EXO Karkasse. Es bleiben ca 45g Schlauchgewicht und bei mir 40ml Flüssigkeit.
