Abstract
The shock absorber mechanism for a bicycle (10) is a device mounted between the handlebar stem (4) and fork stem (5) of a bicycle and includes a sleeve case (11), a spring (18), and a free cushion bushing (20). The sleeve case (11) is mounted to the lower edge of the handlebar stem (4) and joins when the upper portion of said fork stem (5) slides freely and does not rotate. The spring (18) is arranged between the sleeve case (11) and the fork stem (5). The free cushion bushing (20) is mounted to the lower edge of the sleeve case (11) and can be freely installed and removed as well as slide on the outer peripheral surface of the fork stem (5) controls relative movement of the handlebar stem (4) and the fork stem (5) caused by friction on the outer peripheral surface of the fork stem (5). One purpose of the present invention is to allow for easy adjustment of the dampening characteristics of a dampener depending on bicycle riding conditions and rider requirements.
