The question is, did any manufacturer ever come up with a centerpull arrangement that had integral in the design its own pulling point, so that nothing needed to be attached to the headset nor the rear seatpost bolt? A quick search of my memory nor books I have turned up anything. Such a device could extend up from the center bolt the same one or two inches the common centerpull arrangement now has.
