There seems to be a consensues that a good motion ratio to shoot for is around 1:1. However, I'm finding it very hard to get that ratio totally constant, from the first .1" of movement to the last .1". That is, no matter how I seem to configure, there's a measureable amount of rate change (rising or falling) through the rocker's total travel from full bump to full droop.
I know that alot of rising or falling of spring rate creates all kinds of complexities... so just how much rate-change is acceptable through the suspension's full travel? If there is a progression from say, 1:1 to .9:1 over the course of that travel... is that acceptable? What about .8 :1 from ride-height to full bump (etc., etc)? In other words, just how criitical is this measure.
Again, I'm just finding it very difficult to get a totally flat spring-rate through the full range of motion -- full droop to full bump -- and need some idea of what folks feel the limits are.
Thanks for any help in this tough area.
