I am working a rear Spinergy and it needs a new freehub locking thread. My idea is to use a section of a broken hub as a top hat lock ring much like a chain ring nut and bolt setup.
If you can understand the diagram.
SO does anyone have a broken damaged freehub i could have that has this style of Shimano freehub location.
