the exact frame you're seeking is going to be found mostly in three places:
used. there are some bikes like that with somewhat modern features. Soma, Surly, Salsa, Gunner?
small domestic fabricators or custom with a $$$ price tag
very few new options. Soma has some NOS Smoothies but only in 66cm. Rivendell is neo-retro, so what's wrong with quill stems and lugs?
disc brakes are almost universal now. just because Froome doesn't like them doesn't mean they're not perfect for 99.99% of everyone else who is not a professional racer.
