I have a full 105 set that's laying around, I wanted to build a bike for my wife, but I can't seem to find any information on converting an old frame to equip STI components. I've tried the search function, but it just shoots me to a blank screen.


At the moment, I have a 48 CM frame/fork, it has a quill stem with drops.

Can anyone give me an idea of what else I would need?
