A bicycle rear suspension linkage system comprising an elongate seat tube having an upper pivot mount rigidly attached to the upper end thereof and an axle receiving bracket rigidly attached to the lower end thereof. An upper rocker is pivotally connected to the upper pivot mount with a lower rocker being pivotally connected to a lower pivot mount rigidly attached to the axle receiving bracket. The linkage system further comprises pairs of seat stay and chain stay members, with the upper ends of the seat stay members being pivotally connected to the upper rocker and the front ends of the chain stay members being pivotally connected to the lower rocker. Additionally, the back ends of the chain stay members are pivotally connected to the lower ends of the seat stay members. Also provided is a shock absorber having a body portion and a reciprocal piston rod, the distal end of which is pivotally connected to the upper pivot mount. Pivotally connected to and extending between the upper rocker and body portion of the shock absorber is a pair of upper link rods, while rigidly attached to the body portion is an elongate alignment rod. Pivotally connected to and extending between the lower end of the alignment rod and the front ends of the chain stay members is a lower link rod.
