Schwalbe Tube SV 19 29/28/27.5" Presta

[tab name ="DESCRIPTION"]

Made from Butyl Rubber, Schwalbe tubes are well known for their extremely high air retention and elasticity. Schwalbe tubes undergo a vulcanization process which ensures constant wall thickness and high air pressure retention.

All tubes are inflated and stored for 24 hours to test the air pressure retention. Afterwards, each tube undergoes a careful visual inspection.

Only a good quality tube can cover very many tire sizes which aren't possible if the tube isn't highly elastic in nature. For example, tube no 17 can fit tire widths between 28mm and 47mm.

Airtightness - Apart from the quality of the ingredients, the purity of the rubber mixture is crucial to the quality of the tube. The base material is therefore sieved at enormous pressure through seven filters before being extruded. All tubes are inserted into a mould and inflated for vulcanization to ensure constant wall thickness and high air pressure retention.

Reliability - All tubes are inflated and stored for 24 hours in order to test for air pressure retention. Afterwards each, individual tube undergoes a careful visual inspection. This special quality control helps prevent unpleasant surprises and is why, over many years, Schwalbe tubes have become highly respected for outstanding reliability by bicycle dealers.

Group tube system - Only high elasticity and good quality allows a tube to cover very many tire sizes. Tube No. 17 can fit tire widths between 28 mm and 45 mm and that is a big advantage to the trade and simultaneously it vouches for the tube's quality. Only an extremely high-quality and reliable tube is up to to this requirement.

Valve - All valves are nickel-plated and threaded and valve inserts are replaceable. Also, Schwalbe tubes with the classic bicycle valve are capable of pressure testing thanks to a high-pressure valve seal. And it is plain to see as each tube is crowned with a transparent polycarbonate dust cap.

[tab name = " ABOUT SCHWALBE"]

Schwalbe quality standard for bicycle tubes

• All tubes are inflated and stored for 24 hours to test for air retention. Afterwards, every tube is carefully checked individually by visual inspection. The special quality control prevents unpleasant surprises. The Schwalbe tube has been valued by German bicycle dealers for its high reliability for many years.
• Besides the quality of the ingredients, 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 mould for the vulcanization process. Only this ensures an even wall thickness and high air retention.
• Only an extremely high-quality and reliable tube is equal to these demands.
• All valves are nickel-plated and threaded. The valve core is always replaceable. Also, Schwalbe tubes with a classic bicycle valve can be inspected for pressure as they have a high-pressure valve core. As an external indicator, every tube has a stylish dust cap made out of transparent polycarbonate.
• The Schwalbe tube is the only tube that carries the “VSF all ride” quality stamp. VSF is an association of particularly dedicated and quality-oriented German bicycle dealers.
