Wondering about what specifically makes a linkage give a RISING rate.
Specifically,on a design like the Canfield F-1,a parallel linkage.
Is it the angle of the link that the shock pivots on that does it?

If anyone has any technical info on this subject,I'd appreciate it.

The Canfield frames are a rising rate suspension. It does have alot to do with the angle the shock is engaged at but the upper link also has an effect on it. The wheel path also has alot to do with the "feel" of progressiveness. A forward wheel path feels more progressive simply because the forces are "punching" forward in to the object instead of swinging out of the way of the object, rearward wheel path. Radically forward almost feels like it packs up prematurely. The distance the linkage moves across the arc in relation to the distance it swings inline with the shock is what you want to look at. You can move the rear wheel alot across an arc before the link swings substancially forward using shock stroke. It all comes down to the relation of the rear wheel travel per shock stroke distance. I don't want to go into much detail but if you want more PM me.
