I agree the in car adjustment is pretty sweet. Tien, Cusco have those as you know. My PowerTrix CO's are very nice and ride great. I only have 8kg/6kg spring rates as of now and they ride great on the street. Stiff but not unbearable. What's cool tho, is they have a whole line of spring upgrades if you ever want to go stiffer. That's my plan right now.
