摘要： A suspension system for a bicycle having a frame with rearward and forward ends and a fork means rotatably mounted on the forward end thereof and having a pair of downwardly extending fork arms. A pair of arms are pivotally secured to the lower ends of the fork arms and extend forwardly therefrom. A wheel is rotatably secured to and is positioned between the pair of arms. A pair of spring support rods are pivotally secured at their lower ends to the pair of arms and extend upwardly and rearwardly therefrom. A bracket is secured to the fork and extends forwardly therefrom and has the spring support rods movably extending therethrough. An upper pair of springs are mounted on the upper ends of the spring support rods above the bracket and are maintained thereon by acorn nuts or the like. A lower pair of springs are mounted on the spring support rods below the bracket and are maintained in position by an adjustable clamp means secured to and extending between the spring support rods. The clamp means may be adjusted so that the springs on the rods are equally tensioned. The springs are normally in compression.
