Looking for something like Argon18 3D system

[ro1324]

I m getting old and I would like to increase the handlebar height by just moving the 10mm spacer from above the stem (right under the plug) to below the stem. However, doing that causes the handlebars to wiggle around the headset in such a way that makes the bike unrideable.
This is a look 585 that has already serious issues with the poor quality pressure plug fixture that allows for very minimal tightening force to be applied before the thing starts to slip.

Is anyone aware of an aftermarket headset part that would do the job? Something that could possibly work similarly to the Argon18 3D headset?

Also if any owners of look 585 have any suggestions on how to fix this...please let me know.

thanks!

Riser stem?

Have you tried using a new star nut or expansion plug.

Also make sure that if your spacers have ridges that they are installed correctly.

Or try your LBS - possibly a low cost solution.

thanks for the reply
I thought star nuts are no go on carbon forks...?
I bought a used felt f1 that came with a pre-cut fork and pre-installed plug that seems super solid. I can't remove it and I don't know what's underneath the cover I only see the nut hole.
As I said the expansion plug on the 585 seems like a real POS.
I wish I could have the same setup on the 585 that I have on the felt.

BTW the spacers certainly have no ridges...I actually have never seen ones with ridges.

I guess I will have to go to a bike shop...

That is what I understand if your steerer tube is carbon.

Cane Creek is one maker of nested (what I meant by ridges)

I had a similar problem with the expander nut on my bike slipping. A bit of Araldite epoxy glue solved the problem for me (cleaned the inside of the steerer with some alcohol first). Just make sure you set the expander low enough so you can cut the steerer if you ever want to.

In the interests of light weight, it's surprising that high-end bikes still rely on funky expanders in the steerer to compress the headset. A captive nut held in place by epoxy/carbon would be considerably lighter and more secure, at the cost of having to produce the steerer in a couple of different lengths. You could retain some adjustability by having the bolt set low in the steerer and using a longer bolt. Earn fashion points from 'slamming' (ugh, I hate the constant use of that term) your stem, and weight weenie points for cutting your steerer and the compression bolt to the absolute minimum
