I have a slight doubt regarding rising rate. Does it refer to only the wheel rate or also to the Installation ratio of the rocker.
Rising rate - Increase of wheel rate with increase in ride (bump).
Installation ratio = Spring travel/Wheel travel
Installation ratio falls with ride
Travel at spring end falls with ride.
Much more travel required at wheel end to provide same travel at spring.
Thus it seems that a falling Installation ratio would be ideal.
But ,
Wheel rate = spring rate * (Installation ratio)^2
I'm confused as to whether the installation ratio should be falling or rising?
With my current geometry I'm getting a falling installation ratio, which I feel is making the wheel go up more for a definite amount of spring travel. This seems correct but then I'm getting a falling wheel rate. Please help. Correct me wherever I'm wrong.
Thanks
