There's a new fixed gear boutique opening in London soon, 14 Bike Company. And it looks pretty nice.
Don't ask me for coordinates because I don't know although I'm guessing Brick Lane or thereabouts is the direction. Also, if I got this right, they will be only selling their own '14 Bike Co' house-brand track bikes built-up by themselves, and maybe framesets too.
