CONTINENTAL CROSS INNER TUBE 42MM PRESTA VALVE 700X32-47MM

Designed specifically for cross racing, the Continental Cross Inner Tube 42mm Presta Valve 700x32-47 fits all 700c cross clincher tyres between 32 and 47mm in width, meaning that you don't have to resort to using an undersized road inner tube. Constructed from high-quality butyl rubber, these tubes give extra protection against punctures and allow you to roll fast around the Sunday morning race course.
