it has a very small amount of movement which is what I want as I am after looks rather than function,it has been tightened/compressed an inch which if you get into pychics(boring to me)means the more you compress the less the springiness also you have to consider with the bent fork it gives it more leverage/movement because the fork is more horizontal compared to a straighter more vertical fork,if you put it on and don't compress it at all it should work considering the spring rate is close to half of 750lbsHow well does that ride with the heavier spring on it? I was looking to use a one of the shorter 450lb mtb spring with mine, instead of the conical.
