buying a bike for my wife (online) because i don't want to spend $$ on something she might not enjoy (she SAYS she wants to try to start riding).

anyhow, i have seen some less $ bikes with quill headsets/handlebar mounts... i knwo that i can adjust this up/down within reason, but on a threadless headset i can easily swap out stems and move fore/aft pretty easily.

likely she will not be getting a womens specific frame and I will be doing her setup. so i will buy a size below her 'height' requirement so that her top tube length is appropriate. Just want to make sure that there is sufficient adjustability in whatever i choose.

i ahve been searching on google and here, and most vids i have found for adjustment are typically for tension on the quill...

help if u can thx
