Thanks for the clarification. I never raced, so I can't understand that drive to trim grams.
One tour that I did with ACA had a guy in the group that had been an amateur racer. He would pull up next to you, stare at you for several seconds and then launch his attack. I am not kidding he was on a LHT, four panniers, and suddenly he would try to drop you. And of course none of us participated in that so we were all easy to drop.
