I asked this question awhile back, but, I figured that I would ask again anyways to see if any new members have joined the "SS Club." Anymore single-speeders out there? If so, what are you running? I just upgraded my hubs, and fork. Paul single-speed hubs, and a Marzocchi QR20 fork (ebay). I will tell you, it is an addiction for me. At first I hated it, then it became more of a challenge, and it makes the same trails that you run over and over again, more challenging, and sometimes more interesting. I will never give up my FS bike for the rocky stuff, but single-speeding sure is addicting to me...
