I'm 5'6" and weigh 138 pounds without gear so I really wanted to get that extra inch of sag. I noticed that after I sprayed the threads with a little WD-40 that top lock ring it spins pretty freely (by hand) once you loosen it with a punch, or in my case, a tire iron.
I figured the adjuster ring should spin just as freely if it wasn't pushing against that damn spring. It took me a moment, but I noticed that I could wedge a tire iron between the one of the spring coils and a frame cross member and use that compress the spring enough to spin the adjuster. It worked like a charm, I can get both feet on the ground now. :thumbup: Don't forget to wrap the iron with some cloth tape so you don't mar the spring or frame.
