摘要

The bicycle frame (10) has a sub-frame (6) configured to move with respect to the main frame (2). A shock (4) regulates the motion of the sub-frame with respect to the main frame. The shock regulates the motion of the sub-frame with respect to the main frame, and has an end pivotally connected to main frame and second end. A linkage (8) is pivotally connected to seat tube at one end while another end is pivotally connected to the second end of the shock. Seat stays are provided on each side of the linkage and forms a concentric pivot between the linkage, one seat stay and one extension arm.
