I have an old retro bike that still uses a freewheel. I have a spare Sachs LY95 8 speed freewheel, it is comparable to this one:

Except it is 8 speed instead of 7. How can i fit this on a Tacx Flux S?
If this has been aswered already somewhere else a link to the solution would be appreciated as well, I couldn't find it myself.
