Wanted ISO 1-1/4" threaded headset


Retro Newbie
Hello everyone! I'm looking for a silver (or black) 1-1/4" threaded headset to fit in my Alpinestars Almega DX 1992. Thank you for the help!
I have a black 1 1/4 headset fitted to a Cannondale m1000 frameset that I'm happy to let go. Not sure on the thread standard (if it's ISO) though...
