Valve Information


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

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

Technology:


Inflation Pressure Stability
A Schwalbe inner tube maintains the air much longer. The quality of the inner tube is already determined by its raw materials, through the ingredients and the purity of the rubber compound. During vulcanisation, each Schwalbe tube is placed in a mould and is then inflated. This is the only way to ensure a uniform wall thickness and excellent air retention.

Reliability
Rigorous monitoring that ensures the best operational reliability: each tube is inflated in the fabric and stored under pressure for 24 hours to check the air retention ability.

Tube Groups System
Due to its high elasticity and quality, a single tube covers a large number of tyre sizes. For example, tube no. 17 works just as well for 28 mm wide tyres as for 47 mm wide tyres. Only an extremely high-quality and reliable inner tube can meet this requirement.

Bought this one as a emergency tube to put in my backpocket when riding. Lightweight and quite small, that was exactly what I was searching for. I had to use once when I did cut open my rear UST tyre and worked like a charm.

Good quality tube, holds the air for a long time and really lightweight (claimed weight is true). I recommend it as a spare tube in case of a puncture.
