what is the headset model

goodone said:

Bought an oryx 2004 racing 2100, the headset needs replacement.
the head tube is 50mm OD
Bought a FSA Orbit IS, did not work.
Please help.

The Oryx website only identifies it as a Cane Creek unit. Have you tried
contacting Oryx?

Failing that, have a leaf through the FSA Headset Book - a 15Mb .pdf
download:

The Cane Creek ZST (No.10) on page 12 of the pdf (labelled page 8 in the
document) looks a likely match, but check against the dimensions of the
part you have.

They did not provide telephone number, and I sent a letter to them, no
replies yet.

The bearing is caged , but not sealed. I measured the headtube, it 50mm.

Whoops, I think I misread your post. You were looking for Oryx,
not Cane Creek. Well, maybe Cane Creek can help ;-)))

I wonder if you looked at the reference I gave you:
