The published research you are citing is shown in this thread- both links and direct quotes from articles on the website.
The published research shows...
- that fender setup is not even as aerodynamicly beneficial as some race wheels(so a 40+mm rim).
- that bag in front is a detriment to reducing wind resistance when in cross winds, when climbing, and when on flat road.
- that bag setup is only aerodynamicly beneficial when in a super compact tuck(with your hands apparently on the stem, if the pic is to be believed).
^ those are things Jan has said.
And then you need to add in the reality that if aero gains are important...just ride a bike that has a frame profile meant to reduce drag, and use a tire/wheel combo that provides comfort while also reducing drag.
Again, this is stuff that Jan has concluded from his research and is posted in his articles.
