Abstract
An improved shock absorber for use in the front fork suspension of a mountain bicycle includes a housing having a pair of telescopically-arranged cylinders containing a rebound damping piston, a compression damping piston, and a lockout damping piston arranged on the opposite side of the compression piston from the rebound piston, a manually-operable lockout shut-off valve being provided that is operable independently of the compression damping piston between a closed lockout condition in which the lockout piston is activated, and an open condition in which the lockout piston is de-activated, thereby to change the operating characteristics of the shock absorber. The compression piston, the lockout piston, and the lockout shut-off valve are connected to define an assembly that is removably connected as a unit with the upper end of the shock absorber housing, thereby to permit removal of the assembly for adjustment of a flow control device associated with the compression piston. An independently adjustable rebound piston arrangement is provided at the lower end of the shock absorber housing for damping the rebound strokes of the shock absorber. All of the pistons are provided with blow-off valves so that the return action of one piston does not influence another piston.
