Again, thanks to all for the replies. The "you da man" award, however, must go to baxtefer for suggesting those fixed gear gallery bikes (how the hell did you find them, anyway?). Both owners responded to my emails with amazing amounts of technical info, pics, and genuine goodwill. As soon as I can put it all together I'll leave a "definitive" post with all the links, downloads, pictures, and whatnot that they supplied.

Now, I am feeling very confident I can do this project (whereas before, the Sheldon Brown site just scared the poop out of me).

And to whet your whistle for the future posting, one of the two bike guys said he has created a two speed conversion for SRAM hubs...and he'd be willing to do it for $100 provided you supply the hub.

Have a great week, all. It's the beginning of finals for me (I'm a teacher) so don't expect that post before the middle of next week.
