Continental Compact Tube - Presta 42mm Valve - Black (20 x 1.25-1.75)

Continental: High quality butyl tube with removeable valve core ideal for regular use. All 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. Hermetic Plus options contain a higher butyl amount and wall thickness which retains air longer and improves puncture resistance.
