A bicycle inner tube including an annular envelope defining an interior gas compartment and a connecting means operatively associated with the annular envelope. The connecting means is configured to selectively engage either of at least two different styles or sizes of inflation valve. The two most commonly available styles of inflation valve used in the bicycle arts are Schrader valves and Presta valves, however, other valve styles as well as various sizes of a valve style are suitable for implementation with this invention. The selective removable engagement between the connecting means and a suitable valve provides for substantially airtight fluid communication between the interior gas compartment of the inner tube and the selected inflation valve. The connecting means may include a threaded aperture formed in the annular envelope and configured to selectively and threadably engage an attachment structure associated with each of the various types or styles of inflation valve. A seal may be operatively associated with the threaded aperture.
