I notice when I lift the front of my bike to jump or go over obstacles (compress then rebound) my fork tops out, I can feel it extending to its max and it makes a noise that indicates it has topped out. Is this normal? I can't imagine topping out being good for the fork, same goes for bottoming out but that's not the issue right now. May be I have not set my sag properly- possibly not enough sag? I'm running 15% sag on my 100mm RockShox Tora SL = 15mm sag. Any help is much appreciated!
