These concerns are not important when using the aerobars because they are not used when fine bike handling skills are needed and the weight of the front of the body is supported by the arms and elbows when on the aerobars, not by the hands.

When such periods arent long enough to warrant moving the saddle, I felt that my position was too compromised and it would be better if the change was only 3 cm so that my aerobar position is still better (although maybe not perfect) but that the position when I briefly go back to the base bars is also reasonable.
