I don't understand how the suspension seat on the ck35 adjusts. I know the lever lengthens and shortens the seat travel, but what does the knob under the center do, and what does the folding lever do?
I don't have a CK35 but the knob under the center of my seat is the weight adjustment knob. It increases or decreases the spring tension depending on your weight so you don't bottom out over rough terrain. Turning the knob clockwise increases tension. I also have a seat height adjuster knob below and to the right of the weight adjustment knob. Don't know if you have that one or not.
