This presta tube in particular fits tires from 28mm to 32mm. Even though it's pitched as the right tube for the Continental Gran Prix, it's fills the tire completely. This means take care when putting this tube in to avoid pinch flats. All Continental tubes are seamless and mold-cured (vulcanized) to ensure uniform roundness and improved reliability at the valve stem. Each and every tube passes a stringent 100% quality control inspection
Quality tubes in every size for 406 and both presta and schrader.
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.
The SportContact in a 28mm turns any bike into a racer. All this added speed for your bike with zero detriment to puncture protection and reliability! Extremely fine and strong carcass plies, SafetySystem and puncture protection are all integral features of the Contact tire family. 80 - 85 psi recommended pressure.
