My MTB has Suntour XCM 100mm travel suspension forks with pre-load adjustment (the Stanchion's are 28mm).
My book says to tie a cable tie to the stanchions just above the wiper seal. Then I'm to sit on the bike and get off it again and measure the distance between of the wiper seal to the cable tie. This will give me the amount of "sag".
To get my "suggested sag" I'm then to multiply the "range of motion measurement" by .25. I presume then that this is 100mm x .25 which will be 25mm sag? So I need to tweak my pre-load adjustment until my sag is 25mm?
