I just recently purchased this fork and the other day when I first opened the box I started to rotate the red knob on the top of the fork ( It also has a removal valve cap that says air on it) and everytime i turned the red knob a half turn until it hit the next "click" it would release the air slowly each turn until there was none left. Is that normal? I'm not to sure if thats what they meant by fully adjustable forks.. I doubt it. If you have any knowledge of what might be wrong plz help.
