Hubs should be 6207 and would be freewheel, not freehub. You can make a 6400 freehub work with 6 cogs and the correct spacers. There's a guy on eBay who will make you a set of spacers to fit; he's a machinist who sells tools and spacers. You can find him by looking up shims/spacers on eBay.
Hello Doc,
I think I have two options here. Soon I will have a nice 700c clincher wheelset with the Mavic MA-40 rims and the 6400 freehub. If you were in my position, would you consider acquiring the Tricolor 6400 RD, FD, chain and shifters that match the freehub, or go with the Shimano 6207/6208 Group and replace the 6400 freehub with 6208? that is assuming a 6208 freehub will fit on the wheel. I also like your idea of modifying the 6400 freehub with spacers, then the bike will be back to original components.
