Is it actually the old star nut, or is it the special SI headset cap and expander?

If it's the former I'd replace it with the later and follow the SI expander instructions, i.e. no spacers under headset cap.
Options:
```
Keep the SI
Replace SI with a regular expander
```
Variables: Spacer over stem+expander? SI+no spacer over stem?

It´s quite weird. Headset cap is long and with a thin alu (?) wall that goes 4cm deep inside steerer. Then deep down a start nut reached with a long bolt. Something like this:

I have been thinking about replacing it with this:

But maybe just better to just use a use a conventional expanding bung and a custom @mdcc_tester cap as @Dammit mentioned

The SI bung and cap is closer to the design intention of the star-nut system, i.e. the steerer is braced against the forces the clamps impose, by the deep headset cap.

Or just keep the star-nut.
