I know on Fox rear shock springs, the first number is the “weight” of the spring and the second number is total compressible length. So, if you’ve got a 2.34″ spring on a 2″ stroke shock, you could get away with 0.34″ of preload.
However, I’ve got a titanium spring and I check when I bought it, that the 2″ written on the spring, refers to the shock it was designed for, not the total compressible length. Well, I want to try some preload on it but I’m wondering how much I can play with. Is it as simple as measuring the free space between all the active coils or is it more complex?
Is it a safe assumption that so long as the adjacent coils don’t touch when I bottom the shock, then all will be okay?
