The other day I came to a red light under a somewhat hard stop and I heard a "clang" sound (similar to running over a metal grate) as the front of my bike dipped slightly down and to the left. I'm not very familiar with suspension setup but I pulled over and checked the brakes and suspension and nothing seemed unusual. Now I've noticed the bike feels a bit less stable. It used to be so firmly planted but now it feels like it has a "loose" front end. Currently has just under 4K miles, never wheelie more than a few inches and stay off rough roads. I've searched the forums but I haven't come across this issue. Any ideas on what the problem could be? Any help is greatly appreciated!!!
