Just a quick question,I'm new to servicing my bike so i'll probably sound thick but do you set sag on front suspension forks if they're metal coil springs and not air ? I have suntour xcm which is the default that came on voodoo bantu

    Yes, they should have a preload knob.

    Sort of, preload doesn't change how stiff the spring is, it just changes the preload so that the static riding position is in the right part of the travel. The only way to make a spring stiffer is to change it.
