Unmatched Airtightness: The SV11A tube is crafted with meticulous attention to detail, ensuring airtightness and optimal performance.

Reliability You Can Trust: Every Schwalbe tube undergoes rigorous quality control to ensure outstanding reliability. Each tube is inflated and stored for 24 hours to test for air pressure retention, followed by a thorough visual inspection. This stringent quality assurance process helps prevent any unpleasant surprises, earning Schwalbe tubes their reputation for reliability among bicycle dealers and riders alike.

This versatility is a significant advantage for cyclists and dealers, as it reduces the need for multiple tube sizes and showcases the tube's exceptional quality.

Premium Valve Design: Equipped with a Presta valve, the SV11A tube features nickel-plated and threaded valves with replaceable valve inserts.
