Back with another problem!
Just in the process of fitting an integrated headset to a mates bike. He purchased the Cane Creek 40 with the frame so its the correct one for it (both brand new).
We put the crown race provided on the steerer and then the bearing for the lower part, next was the upper.
Again we placed the bearing in the frame, then the metal/rubber cover ring over it and then the compression ring (I presume its called?) before finishing off with the top cap. It all seems to fit hand in hand however when tightened up with the steerer tube wobbles about a bit as if its not properly seated in to the headset?
Anyone else been in the same boat and resolved it?
Make sure the steerer tube is not bottoming (or should I say topping). You may need to stick another spacer under the cap so that the whole stack preloads properly.
My bet is that you need to either fit another spacer or cut down the fork steerer a bit.
I tried fitting a bigger spacer which actually fits better than the last however I still have play in the headset. There is a gap about 3mm between the top of the head tube and bottom of the cover as if its not pressed in properly.?
It could be that the top cap has more than 2mm of overlap when fitted to the uppermost spacer. I have neglected to account for this when measuring a steerer tube before, but I’d far rather have a steerer tube that’s too long than one too short.
is it definitely the headset and not play in the fork? 3mm is a big gap under the top cover so it ought to be at least preloaded but you ideally want the gap smaller to minimise crud ingress.
Are you doing this on a workstand without a wheel in the fork? That will make it easier to deduce where the movement is. Try assembling the lot and just putting the stem directly onto the top cover without a spacer, you should be able to press the lot together tight enough to remove most of the slack without the top cap. If it still feels noticeably loose then check the split cone that fits into the top bearing is fully pressed in. Add a bit of lube in case its getting stuck on the steerer.
hmm, another dumb question or 2 – is the blue seal under the top cover part of the cover or a separate part? Is it the right way up? Is the split cone fully pressed into the bearing so it protrudes just enough for the top cover to sit on it?
we placed the bearing in the frame, then the metal/rubber cover ring over it and then the compression ring (I presume its called?) before finishing off with the top cap.
Not familiar with that particular headset but shouldn’t the compression ring go straight into the bearing first?
Also the top bearing doesn’t seem to be sitting in the top of the frame far enough.
Are you sure the compression ring – the round tapered one – is properly seated? What happens if you take the fork out and stick the upper headset parts in place in the correct order. Is the compression ring the right taper to sit inside the bearing inner race? Are you 100 per-cent sure it’s the correct headset, the various standards for integrated and internal headset bearings are quite confusing.
Hightower? I didn’t have an issue with mine but I do with my new Chameleon.
I need to take the HT apart to double-check but I think the only difference is the HT has the tall top cover, which may be more recessed.
In any case, as long as everything is ‘pulled together’ correctly it shouldn’t actually matter that there’s a gap, except from sealing point of view – i.e. it should tighten up with no play anyway. It sounds like the split tapered ring is not seated in the bearing correctly..
No the crown race like liked above is fitted on the steerer tube as it should be.
I cant remember what order I tightened the stem/top cap. Should I tighten the top cap first then the two side bolts to clamp the stem to the steerer?

Yes, compress the whole assembly using the top cap (doesn’t have to be super-tight – just enough so there is no play) and then do up the stem. After that the top cap is effectively redundant.
Just in the process of fitting an integrated headset to a mates bike.
Take it to a bloody shop. It’s encouraging that you’re attempting to further your knowledge and skills but at least have the decency to practice on your own stuff before screwing up someone else’s bike.

Not the point, at the start of the year I could barely do anything on my bike. Never really tried so was always back and forth at the bike shop for daft jobs etc.
My plan this year was to further my knowledge and save me time/money going to the shops. About three months ago I built my bike completely from scratch my self and its basically all thanks to this forum and its members helping me along the way.
Next I set out to help my mates and riding buddies to save them some money on odd jobs as well.
If needs be I will take it there but it is probably just something daft.
I did the same thing with medical problems.Got tired of waiting for doctors appointments so just googled it instead.Started doing it for my mates too.
They’re all dead now.

Then again, you might be right; found this picture of a fitted 40 series on the ‘net:
This looks like a semi-integrated unit as you can see the edge of a cup below the blue ring. In your picture it’s still standing proud so possibly not pre-loaded correctly or not assembled correctly (again check that the bearing cartridges are the right way up).
I fitted a Cane Creek 40 semi-integrated (“integral”) ZS headset to my son’s bike and it’s absolutely flush with no gaps:
Also, unless I’m much mistaken, your mates bike is a new Nomad (nice bike!) so here’s a picture of a Tallboy with a 110 headset fitted – again, all nice and flush:
Based on your original picture, it doesn’t look like the top cup is pressed in enough, but it’s hard to tell from an assembled picture – if you remove the fork and take a picture of the naked frame cups, this would help.
One other thing – I’m not normally a naysayer or a great user of LBS services, but fitting headset cups to a very expensive carbon frame is definitely something that isn’t a good area for experimentation and learning! Take great care here… 🙂
Had the same (more or less) issue with a Ritchey P29er (IS headset) and a BOS fork.
The first issue was the one that @colpmentioned – wrong top assembly. I was trying to use a Hope ZS bearing and top cap and it was sitting proud of the frame; switched to a Ritchey top part and it was fitting perfectly*.
*The second issue was that the tapered section on the steerer was very tall; this, combined with the very short headtube meant the compression ring was bottoming out on the tapered steerer before clamping the bearings. This was fixed with a taller crown race.

[s]If it is a Nomad, it should definitely take a Cane Creek ZS top section without a problem.[/s]
I pressed down on the stem bars before tightening the stem bolts and then top cap. Its stopped the wobbling problem but there is still about a 2mm gap.
Starting to think the bearing supplied is possibly a bit too big as it seems that is whats protruding.

This is not correct, as others have mentioned. The bolt through the top cap preloads the bearings and removes play. It is then all held in place by the stem bolts. Of course, all of the headset parts need to be assembled in the correct order first (and it needs to be the correct headset for the frame / forks)
