Absolutely none. But, I use the adjust on the fly ALOT. I'm 300lbs, and my wife is, ahem....nevermind. My point is that between the need to change the preload fairly often, and road conditions dictating what the dampening/rebound needs to be set at....being able to make the changes quickly, and on the fly, is greatness. I am ass-uming that being able to do the same off-road would be just as advantageous. I could be wrong though.....What are your off-road experiences with ES ?
