I expect marketing hype and cost control (1 size to rule them all is very good for manufacturers) is what actually drives sales, I'm saying 650B/27.5" makes most sense for women simply because so many of them are the right size to find middle sized wheels optimal. By 'taken off' i really meant adoption by manufacturers rather than consumers, although obviously mass market consumers just suck at whichever teat is put in front of them.
