Bicycle air shock assemblies with tunable suspension performance

摘要

A bicycle air shock absorber assembly (40) that includes a hollow piston rod (170) that is telescopically associated with a hollow compression rod (180). The piston rod (170) and compression rod (180) are positioned within the casing (140,142) of the shock assembly (40). A piston (176) is supported by the piston rod and divides the volume of the compression rod to form a negative air spring chamber (212) and a positive air spring chamber (214) that includes the volume of the piston rod (170). An optional coil spring (248) is positioned within the casing (140,142) and contributes in parallel with the positive air spring chamber (214) to resist compression of the shock assembly (40).
