Continental Conti MTB Tube – Presta 42mm Valve 26″ x 1.75 – 2.50

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.
