I have a Judy TT fork and am considering upgrading. since it's 80mm now i've read to not exceed 120mm because it will stress the frame and possibly break. I'm wondering if sag affects that?
For instance what if I got a 140mm fork with 20mm sag, or a 160mm fork with 40mm sag? since the only time the fork would use the upper 20mm or 40mm of travel is when the wheel is going down into a dip or if it's in the air, both times it wouldn't have much force applied to it. and even when landing a jump the force it would under go to compress the first 20mm or 40mm is pretty low (less than my body weight) that shouldn't affect the frame much right?
