Continental Compact Tube - Schrader 34mm Valve: Black 10/11/12"

From Continental:

High quality butyl tube with removable valve core ideal for regular use.

All tubes are seamless and mould-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.
