No sorry; it was too long ago for me to remember. The original headset was an FSA though.
I bought new bearings for one of mine and they were very standard and easy to find; the crown race was split too.
Best bet would probably be go straight to Giant HQ.
Tell me about it... It was found in a basement and I'm trying to give it some life.
Do you by chance know what headset to drop in? I'm not sure what would fit the cups.
