I disassembled the headset (nothing I haven't done before), cleaned and greased everything, put together ok.

Now I have a strange rubbing sound from the headset when holding wheel in air and moving left to right, not a creaking sound? remove and reassembled 10 dozen times, swapped cups, still have noise. loosen, tighten headset, still noise.

this headset is somewhat idiot proof, IS headset, top is a bearing assy w/centering ring and bottom is bearing assy that slides over fork race and into bottom of headtube, no pressed in nothing. No clue what I did wrong.

Any help is appreciated.

Thanks.
