Yes I want 1 1/8" but i don't know the diameter of headtube is 46mm or 50mm

You can measure the diameter with a caliber.

That's a tapered headset, 1-1/8" at the top and 1-1/2" at the bottom. It won't fit the addict. It would be too big at the bottom.

The Addict fork is 1-1/8" and does not taper.

You need to get a Ritchey 1-1/8" press-fit, 1-1/8" at the top and the bottom.
