ABSTRACT:
A shock absorber for use in a bicycle, comprises a housing; a piston within the housing and a rod secured to the piston. The housing includes a first chamber disposed on one side of the piston and a second chamber disposed on an opposite side of the piston. The rod includes a rod chamber communicating with the first chamber. A one-way valve is disposed between the first chamber and the rod such that excess pressure within the first chamber is bled to the rod chamber during a downward stroke of the piston; and an orifice disposed between the rod chamber and the first chamber to allow pressure therebetween to equalize.
