A bicycle frame can have a main frame, a sub-frame and a shock. The sub-frame can move in relation to the main frame and the shock can be used to regulate that relationship. The mainframe can comprise a series of tubes including a head tube, a top tube, a bottom tube and a seat tube. The shock can connect to the main frame at a gusset connected to the top tube and the bottom tube.
