A shock absorbing fork for a bicycle or other vehicle having a pair of telescoping struts (3), with upper tubes (4) which are interconnected by an upper crown (5) to a steerer tube (7) at an upper end portion thereof and lower tubes (8) which mount a wheel axle at their bottom end. Within at least one of the telescoping struts, a spring arrangement and/or a hydraulic damping arrangement (S) is provided which is acted upon as the upper tube and the lower tube move toward each other for absorbing impact shocks experienced by the wheel of the bicycle. For shock absorbing forks in which no hydraulic damping arrangement is provided or it is contained within a separate cylinder or cartridge which isolates its hydraulic damping fluid from walls of the telescoping tubes, so that damping fluid cannot be used as a source of lubricant for the telescoping tubes, according to the invention, a predetermined free quality of liquid lubricant (18) is provided in the bottom of the lower tube in a volume that is small enough so as to not be directly acted upon by the upper tube even during maximum (inward) compressive telescoping of the strut, but which is sufficient to migrate along the length of the lower tube without being directly acted upon by the reciprocating motion of the tubes relative to each other.
