Hey @Maj. I’m in tuffnel park and have a diy headset press that you can have if you want.
I used it to install a CC40 in what appears to be your old Pompino :) -

Yeah, I know, but like all sprag / ramped bearing clutch hubs they are relatively heavy, as the bearing contact surfaces need to be steel.
- XTR FH-M9111 weights 237g;
- Onyx Vesper MTB CL MS 142/12 weighs 374g;
- Onyx MTB MFU CL MS 142/12 weighs 417g;
They are pretty cool little machines but, at 500£ a pop, no thanks.

Weight weeniness and obsession with engagement points is why modern hubs became loud.
Sprag / ramped bearing clutch hubs were being made as early as 1903 (Sachs Torpedo) - silent, instant engagement, but heavy (sprag clutch assemblies require beefy hub shells to work reliably).
Onyx, True Precision and Shimano (Alivio Silent Clutch) also produced some hubs like this in the nineties, but the vast majority of 20th century freehubs were the traditional soft-springed low-count pawls/teeth in alloy bodies - light and reasonably quiet but slow to engage.
Then pro offroad cycling became a thing and the points-of-engagement arms race started - even lighter alloy shells, large pawl/tooth count and stiff springs - really light, quick to engage but loud af.
The key to reduce noise (and associated coasting drag) whilst preserving lightness and quick engagement is to come up with a reliable mechanism to quickly engage the ratcheting elements when pedaling and completely retract them when coasting.
Shimano had a stab at this a few years ago with their Scylence (:facepalm:) technology in the micro spline freehubs but it turned out to be an unreliable solution.

I'll be putting up a thread in here soon, once I've had the chance to take some decent photos. - Frame: Fyxation Quiver X

Nifty! What are those clamps called?
