We kicked this around back in the day…let me re-hash this old jpg after I answer your question:
Yes. About 10W at ~21mph.

Thanks Aaron, I like to do long rides with relatively short gravel stretches. And I often pack a third bottle in my jersey pocket. Any extra storage is welcome, as long as the mechanical design of the door doesn’t eject a water bottle on rough roads. Honestly wasn’t considering getting rid of the saddle bag, and just ignored that marketing message. I’m running tubeless right now on 2015 Domane and usually carry a tube in jersey and a tube in saddle bag.
A question that just popped into my head about this (Here for anyone interested) is I wonder how much of that 10w was from the aero handlebar vs just the frame. In the images he’s going from a standard roundbar to the aero Propel cockpit. I cant recall them addressing that in the presentation.

Various reports peg it around 5w, depending on the exact HB configuration.
Yeah thats a number thrown around a lot, and probably accurate enough, so if that is true then the frame itself is ~5w. So in theory if you threw a good aero drop bar on an endurance bike the difference is even smaller.
