Thats the crown race isn't it? Part of the headset really but presses onto the bottom of the steerer of the fork.
What headset are you going to use with your precursa? It should come with a crown race. You'll likely need to remove that one, and put a new one on. Google is your friend for this type of fun.
You are correct, I thought it was permanently attached to the fork but a little prising with a knife and it came straight off.
I'm guessing that my forks are in fact straight 1 1/8 and that I can use the recommended headset from Dolan? The Alpina 36/45 which is on their website.
