Dome shaped M5 washers for Argon 18 saddle clamp.

Hi all

I’ve trawled the internet in search of a specific “spacer washer” or “load spreading spacer” for my saddle clamp (Alloy) and seatpost (carbon). Shipped with Argon 18 Gallium Pro 2017.

I’ve requested the parts from importers in UK and the brand HQ with little to no luck. Maybe somebody out there knows where to get this very specific part?

Spec:

M5 aperture with outer dia 10mm with 5mm stack height. Alloy of some sort. And most importantly it’s hemispherical.

Thanks all.
