well this is just a little project but if the bike turn outs good i will probably be using it frequently. i went to some little shop in the swapmeet trying to find out some more information about this and the dude tried selling me a freewheel and said i didnt need a hub. i dont wanna sound ignorant or anything but the man had a thick accent and i couldnt really understand everything else he said. so from the few responses in this thread and what i have read on other sites i have come to the conclusion that i need to invest on a new hub thats for fixed bikes and a fixed cog?
