I would not use my Roubaix frame without the inserts, gimmick or not. The material in the fork and other places where the Zertzes are placed is kind of thin and I can see how the insert could help dampen and reinforce the movement of the frame in that place under stress.
Only my thought without any proof. I prefer to use things that I need to trust going downhill at 40+mph the way they were intended to be used
