White House K10 - a story of regeneration

[PowerDubs_imp]

I haven't looked into the valving and spring rates of the stock forks/shocks- nor my upgraded to SDBV forks- but I can certainly say no -

"How does adjusting your preload one notch change the front end from harsh to less harsh? Your spring rate is the same no matter where you set your preload."

Is not true. Neither is the valving on many modern suspension.

Although the effect is probably minimal- it still has an effect.

A constant rate spring- would be constant in spacing and diameter the entire way. When they are not- part of the spring is 'softer' to compress first - either on impact- or when squeezed- as the spring doesn't know the difference. So 'pre-load' is just constant load-no different than load from a bump. The soft 'area' gives up first.
