got the 2 cups in the frame, and top cap and little nylon washer

is that it, no expander on the steerer tube like other headsets?

That’s pretty much it. Tighten and forget!

cheers, ive had it on 3 bikes, but got it in my mind there should be a expander wedge!

The newer ones do have a tapered collet. The older ones just a top bearing cap with an o-ring in it. There is talk of the early set up not working very well with long travel forks.

:oops:EDIT, I need to read the posts better before leaving random advice.

You should have a steerer cap, bearing top cap and split ring (old style was a solid bearing top cap with rubber o-ring)

Scroll about half way down and it has a diagram showing the different components on the newer version.
