Abstract: A dual-chambered inner tube and valve system comprising a primary tube and a secondary tube joined by a common valve assembly is installed into the wheel cavity. The primary and secondary tubes are positioned side-by-side throughout the circumference of the cavity with the valve assembly positioned in the rim's aperture. The chambers inflate independently and can be selected by a tube selector valve within the main valve assembly. Since there is one valve assembly of standard dimension for both tubes, rim modification is unnecessary. With the primary tube inflated, the secondary tube is devoid of air and stowed between the primary tube and the wheel, which may be used as normal. In the event of a flat tire, the selector valve is moved to a secondary position and the secondary tube is inflated, effectively repairing the wheel without removing the tire from the wheel or wheel from the bicycle.
