I am new and on my second build. I am installing a CDHpower hub clamp sprocket mount with a 40 tooth. However I notice the 40 too the sprocket also contains the bolt patter for the rag spoke moubts. My idea is to use the metal.spoke clamps from the rag mounts as spacers and bolt tho e 44 and 40 together to make a dual.range stack. The 40 tooth mounting both to the hub clamp mount. Like the old enduros. Swap over as conditions change I figure I can't be the first to attempt this so figure maybe I would ask why I don't find many videos trying it.
