This way of DIY Under Carriage is the by far the best way I found, for a a flatout or a foamie.

Get two slotted Wooden Piece, carve it with a hobby knife  (See image) Fix your bent cycle spoke on that slot, fix the other piece of wood , CA it , slot it into the foamie. The jutting out portion of wood can be supported by two - three pieces of foam. the slot itself can be in a form of two 'S', one small end of the S and the other big end, the small one will absorbed heavier shock and the bigger one will absorb lighter sock

That is for Ved

Thanks a lot Augustine sir
