The SCHWALBE SV15 inner tube is the essential reference for demanding road cyclists. Designed for 28-inch (700C) wheels, it fits tires from 18 to 28 mm width thanks to its remarkable elasticity. Equipped with a 40 mm Presta valve, this inner tube made of high-purity butyl guarantees exceptional pressure retention and proven reliability over millions of kilometers.

SCHWALBE reliability and quality control

SCHWALBE applies rigorous double quality control to each SV15 inner tube. Each unit is inflated for 24 hours then tested twice at the factory to detect any leak before shipping. This manufacturing standard ensures maximum airtightness and drastically reduces the risk of punctures due to manufacturing defects. The uniform wall thickness, obtained by pressure molding, contributes to excellent puncture resistance and increased longevity.

High-performance butyl composition

The high-purity butyl rubber used by SCHWALBE guarantees air impermeability far superior to standard inner tubes. You inflate less often and maintain optimal pressure longer, for consistent performance and preserved riding comfort. This compound also provides great flexibility during mounting, avoiding folds and stress during installation.

40 mm Presta valve with replaceable core

The 40 mm Presta (Sclaverand) valve is ideal for low and medium height rims (rim height ≤ 25 mm). Nickel-plated and threaded, it features a replaceable core, allowing the addition of preventive sealant or replacement in case of wear. This high-quality valve ensures precise inflation and perfect pressure maintenance.

Environmental commitment

SCHWALBE designs its inner tubes with a sustainable approach: the SV15 is 100% recyclable. Manufactured in Germany near Cologne, it reflects the brand's commitment to quality and environmental respect.
