Hmm, I thought SS hubs with QRs would be easier to find. I guess most of the market imagines themselves to be big, strong track riders.

If you're just going to ride singlespeed, I like [MENTION=114951]dabac[/MENTION]'s idea of getting/building a rear wheel for a freewheel and respacing if need be. Most of the 126mm 6/7-speed FW hubs out there are really just 120mm hubs with an extra spacer off to the side, as it was in the 1970s/1980s.
