Boone asked how often Greg applied that amount of force, that allowed the bars to rotate and slip on the standard roar drop bars. Greg's reply was along the lines of "every pedal stroke".

My point is that these bars are not designed to be stiff or ergonomic WRT the bike handling or brake levers. They are first and only about being in a aero position. To start to seek other priorities will lead you down the path of so many others who have given up on these one piece design and adopted drop bars with clip ones if they must also have a fore arm pad and/or aero position.
