Ok, I guess I'm going to go over to the lbs tomorrow. I've been ****ing around with this all night. Somehow I managed to tighten the lockring, and the headset was adjusted seemingly perfectly. I took it out for a spin around the block, hitting as many little bumps as possible, and still heard the rattle/clank.

I came back inside, and tightened the **** out of the headset. It still moved, but was tight tight tight.. took it out for another ride around the block, and I still heard the clanking. It seemed to be less than before, but still was there. The headset def. wasn't loose, as I had over-tightened the hell out of it.

So, any ideas as to where this is coming from? Maybe I just didn't get it adjusted perfectly? But why would it still clank when overtightened?

It kind of sounded like it was coming from the bottom of the headset this time, but who knows.
