M800/620 forks....

I think it's finished now.

I would expect all the 43mm Marzocchi to be the same, but that can only be confirmed by physically inspecting them.  none of the photos in the manuals are the same as these ones.  maybe they're showas in the manual, now that I think of it.

Cool summary Brad. I've never understood "progressive" springs, as even linear springs are nowhere near linear in actual use.

Actually this is a good argument for the longest spring possible, with no spacers, to keep the force curve straighter.

linear would be linear if not for the impact of the internal air pressure rise.  it's effectively a dual spring system, both adjustable to some extent, but one intrinsicly not practically removeable.  you can remove the spring, some of the mitos were like that (one leg only?).

the actual physical spring is somewhat irrelevant apart from the rate and having the correct preload, as long as it doesn't bind before full compression.
