Bicycle rear wheel suspension system

摘要

A bicycle frame assembly having a number of rotatable members configured to absorb shocks and impacts associated with operation of the bicycle. The assembly includes a frame constructed to support a rider and a chain stay having a rearward end that extends toward a wheel hub and a forward end that is pivotably connected to the frame. An absorber is pivotably connected to the forward end of the chain stay and extends to a rocker arm that is pivotably connected to the frame. A seat stay is pivotably connected to a rearward end of the rocker arm and extends to the rearward end of the chain stay. The rearward ends of the seat stay and the chain stay are pivotably connected to rotate about a common axis.
