You did not define in Post
#1 , para 1 what you define as a 'modern' bike.
Maybe i missed another post as I didn't read every one.
Perhaps another way to look at this is:
The frameset may influence the choice of which group you choose...
You may never know until you have the frameset in hand.
Case in point.
Acquired a frame that, upon inspection after receipt, had a top tube a cm shorter than the shortest I told the seller I would tolerate.
Ship it back?
The 14cm stem was toooo long for a solid feel. 13 is my limit on these large frames.
But a 'modern' group,Campagnolo9/10, has nice rounded hoods that allow a more forward placement of the hands. Voila, a solution worth trying, when mated with a longer reach h'bar. The resulting cockpit is very comfortable thru a range of riding positions.
first pic shows rounded hoods that fit the palms of my hands.
lack of shifter bosses resulted in a clamp-on
also clamps for front derailleur cable routing
so an older frame can be made to work.
