All in all the drop is very significant, and my center of gravity has lowered by a lot. The whole ride feeling has changed.

To achieve this, I tried a few mods.
First, getting rid of clipless pedals with a high stack height and going to thin platform pedals + thin soled shoes. This lowers the saddle by 2 to 3 centimeters.
Second, swapping to a more midfoot pedal position.
Thirdly, pushing the saddle as far back as possible, and going for an ultra short stem to maintain the same reach. ( I know, ultra short mtb stems are never used with roadbikes ... but I don't think it's as twitchy as they say -- the human body adapts and accustomes quickly).
Fourthly, swapping to slightly longer cranks (but I still use much shorter cranks than most cyclists namely 145, and 152.).
As a consequence of the lower position I was able to get rid of all stem spacers.

All of these are quite controversial changes to a roadbike, i am well aware.
But for the sake of experimentation, I am going to give it a a good try on the road.
I am significantly lower than before. I don't know how much, but I feel much closer to the ground. And I can touch the ground with both feet while seated in the saddle. it feels awesome. But now sure how it will feel after a long ride...
