Hey Moxley,
I'm afraid a couple of people have already expressed interest in the wheels (pending viewing) but if you want, I can put your name down in the list as 3rd.
But to actually answer your question - yes. Any hub with threads on either/both sides can take threaded freewheels/fixed cogs.
Hello, my first post on here but I am interested in the wheels if shipping isn't a problem.
Forgive the dumb question, but I presume a freewheel can be fitted to the rear hub?
Cheers.
