Vertical and longitudinal shocks imparted to a bicycle seat are absorbed by a compression spring disposed between the seat and the seat strut, with one end of the spring being mounted to a seat retainer that is moveably secured to a pair of slide plates which are in turn slidably engaged with a stationary strut head. A semi round seat secured to the strut head permits the angle of inclination of the bicycle seat to be adjusted. The compression strength of the spring may also be adjusted by urging a cover towards and away from the moveable end of the spring.
