Some smart person please answer
 

Hey, I just bought a new Bombshell Marylin that is inverted and has 8" of travel. First of all, has anyone heard anything about these? and next, when fooling around with it, i iscovered that it only seemed to have about 5 and 1/2 inches of travel. I then took off the top cap things and pressed down on the fork so that it bottomed out. It did in fact have about 5 and a half inches. Then I pressed down extremely hard on the part that seemed to be the bottom, and it in fact went down even more. It turns out that for about the first 5 and a half inches it uses one spring setting, and then i goes to an extremely stiff spring for that last couple inches. Is this uncommon or do other forks have this too? Is there any way i can adjust the stiffness of that bottom spring? any info is appreciated, thanks

It is a way of adding progression to a linear fork (I am assuming it is linear) Most forks now use an air assist or a progressive valving in the oil chamber. Sounds like an older fork with no built in compression damping, this gives it some degree of compression damping

I would assume a not so stiff springon the bottom would fix the problem, but this is a pretty rare fork, might be tough to find info. Is there a possible preload on the bottom of the fork to control the spring rate of the lower spring?

oh good question, i will take a look

Its probably just a thing to help prevent bottom outs. I know most linear forks get really hard before they bottom, it just stops the fork from damaging itself.
