Installing FSA Orbit X headset on Ouzo Pro carbon fork

I'm installing a new Orbit X headset on a Ouzo Pro fork and have a couple of questions.

First, I can't make sense of this aluminum compression ring. Without it, the headset seats fine. With it, the adjusting cone won't seat completely over the upper bearing cup. Can I toss this aside, or is there something else I should be doing to get this to seat with it? The FSA instructions aren't great on this...

Second, is there any need to grease the fork race, cartridge bearings or upper cup? My last headset was a needle bearing one and this is new to me. Many thanks.

I have an FSA Orbit X for a 1" steerer. Seems like an obvious one but I assume you've to the bearing cups in the correct position as far as lower and upper cup?

The compression ring is supposed to tighten up around the steerer. Uncompressed, the ID of the ring is about 1". The slight gap, if any, should be covered by the top o-ring and will not affect the functionality of the headset. The ID of the bearing itself is too large to function without the compression ring.

Another silly question but is it possible that you have a 1.125" steerer and a headset for 1" steerer?

As for the second part, it's no to all. No need to lubricate anything except to ease assembly.
Those are great points. I checked, re-checked, and checked again to see if there was anything like that that i was missing. Unfortunately, I don't see anything like that. My question really boils down to this... the compression ring fits down inside the top bearing, but the adjusting cone won't fit all the way down so that it's flush with the top crown because it has a metal flange on the bottom that butts up against the compression ring. It fits will without the compression ring and I'm wondering if FSA, perhaps, changed the design without updating the (mediocre) instructions. I've posted the photos below. You can see the compression ring installed, the adjusting cone with the flange below it and how well it (doesn't) fit. Am I missing something with this installation?

Thanks for the help!

It looks from the photo like you may have two things confused. It looks like you have the split ring thing going in under the top piece of the headset. My experience is that the split ring is the fork bearing race and the solid ring goes on the steerer just under the final piece of the headset.

However this was really confusing on the last Orbit X I purchased because the fork race was solid on that one and had to be pressed on rather than easily slid down onto the fork.

The most difficult part of this entire installation is making sense of FSA's instructions... from looking at the pictures on the supplied instructions, I gathered that the solid ring was the fork race. I pressed it on (it was tight). The Orbit X picture on the instructions, when compared with the other models, didn't show an installation of the compression ring. That's why I'm wondering why the compression ring was even included-- have they designed it out, yet still included it?

Do you recall if your Orbit X has the flange on the bottom of the top piece of the headset?

These are FSA instructions-

Threadless Headset Installation
Please read carefully. For best results, consult a qualified mechanic at your nearest
professional bike shop.

1. Install the headset crown race on the front fork, making sure it is seated completely and level on the fork crown.

All FSA threadless headset crown races except the DL and The Pig are split to permit easy installation without tools. The Pig and DL crown races may require a fork race punch to seat completely. see eflayer2's post.

2. Make sure your frame™s head tube is properly faced, then install the upper and lower cups onto the frame™s head tube using a headset press.
3. For the XLII cartridge bearing model, cartridges fit only one way.
· For the Xtreme cartridge bearing model, cartridges are pre.installed in the cups and should never be removed.
4. Make sure the crown seal is in place in the lower headset cup. For the DL model install the lower seal onto the crown race. For the Xtreme model (1.1/8l. only), install the conical seal into the crown race with the cup side facing up toward the cartridge bearing.
5. For the XLII cartridge bearing model, cartridges fit only one way.
· For the Xtreme cartridge bearing model, cartridges are pre.installed in the cups and should never be removed.
6. Insert the fork™s steerer tube into the frame, with all bearings in place. Place the top
adjusting cone (the part with the USA patent number on it) on the top of the fork steerer and slide it down until it rests against the top bearing. For the XLII and Xtreme, the compression ring fits directly against the bearing followed bythe cover (see drawing)
I found those on the FSA site-- since they don't mention the Orbit or Orbit X, I didn't pay too much attention. I'm going to resort to calling FSA this afternoon or stopping by my LBS to figure out what's going on with this headset.

Thanks for the help!

everything is alright. When you install spacers/stem and tight it up with Reynolds gismo the compression ring is gonna pop in, don't worry. Out of "special" installation tricks I'd recommend to cover seals (both on cartridge bearings and external) with vaseline. The TH "red" seals are only so-so, vaseline will keep water out for longer bearing life good luck
And you are correct, sir...

With quite a bit elbow grease (and about half an hour of work) I managed to work the compression ring down by installing the stem and using the Reynolds gizmo... as well as weighting the handlebars and rocking the fork back and forth gently-- which was really what did the trick.

Thanks to all for their help!
