Abstract
A bicycle air shock absorber assembly that includes a hollow piston rod that is telescopically associated with a hollow compression rod. The piston rod and compression rod are positioned within the casing of the shock assembly. A piston is supported by the piston rod and divides the volume of the compression rod to form a negative air spring chamber and a positive air spring chamber that includes the volume of the piston rod. An optional coil spring is positioned within the casing and contributes in parallel with the positive air spring chamber to resist compression of the shock assembly.
