I don't remember saying that, but the RD13 does look like they took the DS of the goldix R180 (non SL) and combined it with the NDS of the goldix R160 (also non SL). The Edge 2.0 seems to be an R160. In this case, a goldix road freehub would likely fit. On the rim brake version, the freehub body looks like something you'd find on a goldix, but the hub body doesn't trigger any recognition in me.
I've never been particularly interested in Elite, especially the ali side, so idk if they've made any generational changes. Maybe you could post a pic of your hub Barry, so we can see what you actually need.
