Disadvantage of this approach: doesn't allow you to hang all sorts of period correct french mech all over the frame, and leaves you in the lurch in the event that (a) she decides she wants to out-sprint the delivery mopeds or (b) your neighbourhood suddenly grows some hills.
Advantage: lighter, simpler, and lets the elegance of the mixte frame shine on through unfiltered.
I have definitely considered this. Another downside for me is this is a learning experience and I was looking forward to working on all that goes with keeping it a geared bicycle. I supposed I haven't totally ruled it out yet though!
