Is it just me or is the front suspension really soft? I have noticed that when I unexpectedly brake "strong" it dips down really low. Im not punching on the brake just firmer than normal by mistake (it's my first bike), I don't blame the bike for the dip but I am concerned with how deep it plunges. Is there a preload adjustable setting for the front? Im 6ft 220lbs, Could that be a reason?
