BFSSFG don't read. There aren't really any fixed-specific manuals since they'd be too short to sell.

Most of the freewheeled-bike manuals are all the same. The knowledge isn't that technical so go to the bookstore and find the one with the pictures you like the best and get that. You can honestly do a lot better just reading the forums and googling parts you have trouble with.

Look at these and read the tacked threads at the top of the forum:

And here's a video in Polish of a fixie-bro putting together his sw8 ride: http://vimeo.com/14866383
