Thanks for the replies.

I've already bought balls to repack the headset with no retainer, and if I'm lucky I can drop into my shop and have them rotate the races 90 degrees to move the "indexed" side over to slow the demise of the h/s. I guess that gives me some time.

Oh no, you're reminding me that I may lack the necessary tools to open up the bb too - I've never had a campy bb and I didn't even think of that.
