What headset do I need?

Are 1” all the same or do they differ?

And what’s a half decent one that doesn’t cost the earth.

Cheers

Not all the same there's jis and iso.

If you measure the steerer crown iso is 26.4mm (considered normal i suppose) and jis is 27.0mm.

Its harder to tell from tje frame as the tube i.d. is jis is 30.0 and iso is 30.2.

As for parts, tange still make some nice headsets that don't cost the earth.

However, you need to consider the limits of your stack height.

That looks like a threaded steerer. Stack height (including a cable hanger if used) is the main consideration. I used a new 1 inch threaded IRD headset on my bike. It seems to be decent quality so far. Bought online from SJS Cycles.

Forgot to say you may need to check thread pitch as others have said there are a couple of different standards.

It's a 90s univega, thread pitch won't be a problem,

The only real issue is the crown race, as there really are a couple of different sizes but again, it's a 90s univega so shouldn't be a problem!

I have no idea about threaded headsets.

so, this would work (stack height etc)?

You need to measure the stack hight.....can't tell from a photo.

head tube: 98mm

steerer tube: 137 (looks like there is already a race on there.


(does this help)?

thank you

You need to take the race off and measure the diameter to determine if ISO or JIS.
