So I have the Sante hubbed wheels from the Circuit laying around, and an 85 Schwinn Super Sport frame, so I get the brilliant idea I am going to build a single speed out of them. I get the whole using spacers thing, and I know about the spacer kits available that "should" work on this freehub. But... It has the outer threaded freehub, and from the looks of it, it doesn't have the dual threads(inner/outer) that I'd need to use a standard lockring. Does anyone make a retro kit that has a lockring for the outer threaded freehubs. I think it would look kinda ugly with a big cog sticking out on the end, just to hold it all together. Will a BB lockring fit those threads?,,,,BD
