Question Swapping freehub bodies

[gbarfoot]

I have 2 specialized roval wheels, one HG drive, one XD. I want to swap the freehubs and cassettes. The HG has a nut on the axle that you remove and the freehub slides off. The XD does not have a nut. How do I get the XD off? How is it held on?

Once I have both drivers out do I need to swap axles too? Or can I reuse the axle with nut on the XD driver.

They may well both be from Roval wheels but those are not the same hubs. (so you may not actually be able to simply switch freehubs between them)

The XD hub's end cap will either simply pull off or twist off
impossible to tell from your pic but be aware there may be a circlip or other retainer somewhere so check first before exerting too much force pulling the end cap off
