Need a little extra protection? We stock puncture resistant 20" tubes for a few of the larger sizes and schrader valves. These tubes are basically three times as thick as a normal weight tube. In many cases, you can make your bent virtually impregnable to flats with these tubes, a tire liner, and a tire like a Marathon or Marathon Plus

Extremely air-tight! Less air loss means having to inflate less often. Our unique rubber mixture makes it possible. Extremely reliable! Each SCHWALBE tube is individually examined twice at the factory to ensure air-tightness. Special quality control that prevents unpleasant surprises. In Schwalbe talk, the SV is presta and the AV valve is Schrader.
