    Excellent pictures, great detail.
    What is retaining the carbon hanger, is it a regular circlip that fits in the groove ?

    Yes, it's an external circlip.
    You can see it on assembly pictures

    It was quite straightforward, things often are when you can physically handle them and see how they interrelate.

    Exactly as you suggested in post 2, Part 24 secures the brake calliper hanger but plays no part in the wheel - chain assembly.

    All the elements are aluminium so gently does it.

    Image is from JHP.

    Too important to assume so had to be sure.

    Thanks for the effort you put in BABA/Phil911.

    In reality, the reducing spacer is in aluminium and the special screw in steel.

    I made the screw in aluminium because aluminium is enough strength (this is not a structural component) and easier to machined.
    Also lighter even if the difference is tiny. I also prefer this material for its best aspect. Even if the anodization was not very successful for this part.
    It is part of the first components we try to anodize with my father, but we didn't know that aluminium alloy with copper (like the 2017 alloy) becomes black after its soda bath and that it needs another soaking in nitric acid, just before the electrolytic solution soaking.
    Other series were better after that (except for black colour, it didn't work...).

    Yes that is correct, the original screw is steel.
