I had to lift my bike over a tree that completely crossed a paved trail. I later noticed that something didn't seem right with the way the bike handled. I stopped at a watering hole and parked my bike but had to move it out of the way for someone. For some reason I had to lift the bike and that's when I noticed the loose wheel. I was glad to get that figured out. Must have knocked the lever while trying to get my bike over the tree.
