Shock absorber for a bicycle front fork

A shock absorber mechanism for a handlebar and fork stem of a bicycle head tube, comprising;

• a sleeve rotatably mountable into a head tube of a bicycle frame, said sleeve having upper and lower holes formed therein, a handlebar stem mountable in said upper hole and a fork stem for supporting a front wheel slidably but non-rotatably mountable in said lower hole;
• a removable spring disposed axially in said lower hole, wherein said spring is compressible and extensible within said lower hole in response to slidable movement of said fork stem;
• and
• a removable friction member retained at a lower end of said lower hole at least partially within said sleeve, which produces friction in response to sliding movement of said fork stem;
• and
• a removable check plug disposed at the lower end of said lower hole which retains said fork stem and said spring within said lower hole.
