It makes sense as a deluxe replacement for the double adjustable stem like on the Continentals, not sure what year that stopped being factory equipment though, or even optional. The World Travelers/Varsities I've had were electroforged frames and if I remember right, had the smooth stem that I refer to as "the horse neck." Then there were a couple with the inverted binder bolt stem. Neither of those bikes struck me as deluxe enough to have the Razor.
I will say the Razor stem definitely doesn't take value away from those bikes.
