So what I discovered when I reviewed the patent on this thing last night is that the forward lower pivot does not need to be below the rearward lower pivot. Does that make any sense, or have I gone full redrum at this point? I had to impose constraints about the relationship between the upper and lower pivots, but not the vertical relationship between pivots on the same rocker. OK, I’m pretty sure that one didn’t make any sense. Redrum.
Basically, I can rotate the front of the lower linkage up, away from the bottom bracket shell. There are some interesting things that happen when you do this but overall it’s just an option, and I’m at the point where design options damn near make me weep. Right now options are cause for celebration the way finding out you can scratch your nose against the ground when buried to your neck in sand is cause for celebration. A little wiggle room when you thought you were all out of that sort of thing can be a pretty big deal.
Still no magic wand, though. Because the real beauty of the system is how the lower link tracks right along the chain, you really can’t just go putting it anywhere without screwing up the system.
Anyway, back to the drawing board.
