You are correct, my comment on the frame was wrong. In my defense I remember hearing that quoted in the same sentence where they said it was the weight loss was absorbed by other additions.....That is a good list of the weight increases, but just to be accurate over the 1st comment about the frame, it is ~50% stiffer but this all aluminum frame is actually 99 pounds lighter than the steel C6 frame. There are also some other weight savings that help get the ~49% front, 51% rear weight distribution.
