It is currently a 9 speed which I think I will keep as it is, but was wondering if the front derailleur hanger on the 18 speed was compatible if I were to add another chain ring ? I can’t see any holes in the frame that the 18 speed has.
The front derailer mounts to a bolt on adapter, you can see it in these pictures:

I will be converting from flat to drops – I’m guessing there would be no problem with that?
You will need new shifters and brake levers, probably new cables as well. I have mustache bars, they use road brake levers and bar end shifters.
