ABSTRACT:
A bicycle rear wheel suspension system includes an upper link and a lower link both pivotally attached to the frame and to a rear stay member. An instantaneous center of rotation of the rear stay member is defined at an intersection between an upper axis extending through first and second pivots of the upper link and a lower axis extending through third and fourth pivots of the lower link. Throughout a travel distance of a shock absorber of the suspension system, the instantaneous center of rotation remains below an average chain torque line of the bicycle, the lower axis remains above an axle axis extending through the rear wheel axle, and a portion of the lower axis defined between the third and fourth pivots extends below the average chain torque line.
