ABSTRACT:
A torque transmitting, bicycle frame coupling (50) is provided which connects to the frame tubes (1, 11) of a bicycle. The coupling (50) replaces a portion of the tubes (1, 11) and has clutch teeth (3, 7) on their engaging faces. Installation of two such couplings (50) allows a standard bicycle with standard wheels to be temporarily divided into two pieces, leaving sheathed component cables attached, but removing then from the frame tubes (96, 98) through use of quick connect cable clips (74). Once divided, the bicycle fits in a case (100) with a combined height, width and girth measurement no larger than 62 linear inches and can then be put back together with no loss of original frame geometry or stiffness. Each coupling (50) is actuated, pulling the tubes (1, 11) together and joining them through use of specialized clutch teeth (3, 7) under compression provided by a threaded lug (2), a removeable-shoulder lug (9) with a removeable shoulder (4) and a threaded coupling nut (5). The removeable shoulder (4) makes the nut (5) and shoulder (4) replaceable, and makes possible an additional shoulder (10) on the tube connecting end of the removeable-shoulder lug (9) to keep the nut (5) from slipping onto the tube (11).
