If I ever go back to a steel frame with threaded fork and quill stem, I'll seriously consider the factory 5 oversized quill stem. removable faceplate without being butt ugly.
I did think about the Factory 5 one at the start, (also close friends) But i might have won something off the Bay that may fit the theme better. Stay tuned.
As for single speed or Fixed, i am undecided yet. But I am inclined to go SS as will certainly use modern brakes all round.
