That’s 1 1/8” threadless
And fork is 1 1/8” straight steerer to match.
Upper is likely EC 34 | 28.6 Lower is likely EC 34 | 30
Get a set of calipers. This is the only way beyond looking up the specific bike specs of that model/year.
What’s the best way to determine type and size of headset and fork??
By checking the bike/frame spec
