Principia 650c - one for the miss

Graham will be up for sale soon! Too big! :(

However this isn't:

This frame has forum history. A good bit of history.
It's lovely and light. (And, have to say, @keanulooser is equally lovely. What a dude!)

This is for the miss. She currently pushes along a 1950/60/70s Bridgestone girls' town bike with 22inch wheels. It weighs a ton. It's an incredible bike but not for road cycling proper.

Graham's tt is 54 c2c and st is 54 c2t. The miss is 5ft4 so there may be an issue with the st.
I could chop 1cm of it, it's quite far extended.

I'd like to build with 165 cranks, but might have to go short, 155 or so, like these.

Does anyone 5ft4 ride a 54 st?
