Actually it doesn't matter too much which end they are attached to.  The
reason that I can't relax the steering angle any more is that the rod ends
only have a limited travel in the fore-aft direction.  I could get a more
useful range of adjustment by making a different front part.  One thing that
does change with changing the steering axis is the angle of the front and
rear frame to the ground.  As a relaxed the pivot angle the cranks rose
higher above the ground.  This means that two variables change at the same
time.


My thought was that having a joint on each frame would allow pivot angle
change without frame height/angle change.

 Which has the effect on the handling- change in position of the front
mass or change in pivot angle? Probably both!


I agree

Greg's projects always give me food for thought.  Perhaps the head tube
beside the front wheel is a good way to build a lowracer TT type bike like
Laurent and the other Jeurgen (Maier) are working on.

The very low front frame piece (maybe combined with bending it out at the tire area)

might be a useful idea. Is it better or worse than what
the faired speed racers use?
