I rode one of the pre-built wheels from Sheldon that had the Sovos hub. Lasted for a bit, but eventually the threads for the cog stripped when I tried to skid stop at an intersection. Cranks stopped, wheel kept going. Luckily I run a front brake. Personally, I'd spend a little more for a better hub. BTW, I think they are spaced at 120mm unless they have a 110 option.

You could use a BMX hub and a cog w/ a BB lockring w/ Loctite. Or spread the frame, 10mm isn't much for a steel frame.
