This pdf file has info regarding Marz springs.
I just bought spring number
850660/C
from Bikewagon on Ebay for $10. He described it as
80mm
Spring K=6, 5-8, 3
850660/C
Hope this helps
Sorry to hijack the thread a bit, but when you say place one spring on top of the other, is there any type of washer in between, or do you literally place one spring directly on top of the other? I have a situation where I have a 110mm travel Z1 BAM that has two top out springs stacked on top of each other. I was wondering if I could add one of these top out springs on top of the main springs, giving the fork 130mm. Something like this:Ottoreni said:When you pull out the stock medium springs, you will notice it is longer than the long red spring in your package, but when you place the blue spring on top of the red spring, these two springs will equal the length of the stock spring. They go into the legs the same way, small blue on top of the longer red.
This is called a "dual rate" spring set up. It is suppose to give it a plusher feel I believe.
good luck
