Sinn

I want to run a free bearing hub on my set of road wheels. I prefer these, period. But I also want to be able to run a single-speed freewheel every once and a while when I join large groups of road bikers for long rides on the hilly terrain around where I am in Southern California. But this is a problem: I do not know of any flip-flop free (i.e., non-cartridge) bearing hub.

I have thought of one possible solution: get a fixed/fixed hub or just a one-sided fixed hub, like a Dura Ace (my favorite, aside from the Superbe Pros) and screw a freewheel hub onto it.

My questions:
Has anyone done this? Has it worked? Will I risk destroying the hub doing this with a freewheel? Or is it just as safe as running a fixed cog?

Thanks in advance.

P.S. I am a picky person when it comes to my bike. There will be some who will say, "Why do you want to do x, when you could just y?" I will ignore these responses. And let arguments on whether I should prefer cup and cone set ups or not take place in another thread (or just do a search through the forums, there are arguments on both sides aplenty). Just FYI.
