Valves are nickel-plated, theraded, with replaceable core
A Schwalbe tube is not just any tube. The rubber is filtered, extruded, and meticulously molded for constant wall thickness and superior airtightness. Then, they are tested and closely inspected, resulting in high reliability. Since the rubber Schwalbe uses is highly elastic and of excellent quality, one tube can cover tire widths from 1.5" to 2.5". Each replaceable core valve is nickel-plated and has a clear dust cap.
