Sorry If Im a novice at explaining this . So I have tri/road bike I have not ridden much in a couple of years. Prior to riding it recently I knew something wasn't right with the headset, its kinda a long story. So when you ride there is play in the headset area especially when braking. Like I said there is more to it but I'll get to today when I took it apart for inspection. I noticed the top headset bearing has some kinda of insert to tighten it up around the fork but the lower one did not and I tried to switch them the upper one would not sit down where the lower one sits in the correct spot if I used the upper up with the insert. I sat up about an inch higher. In the photos I included for people to see, I took the lower bearing and put it up top to show there is quite a gap meaning its way bigger that the fork tube . Can anyone explain whats going on here ?

Here I am showing the lower bearing up top so I could photograph it . And you can see its quite larger then the forker steer tube .
