My bike frame is already a little too large for me anyway so when I felt too stretched out while on the aero bars, I decided to try the trick of rotating my seapost 180 degrees so that I could mount my saddle so it would sit forward more.
I took my saddle off, turned the seapost 180 degrees, put the saddle back on, and positionned the saddle in the most forward position it would go. This brought me much closer to the aerobars but more importantly, my legs felt like they were applying a ton more power on the downstroke of my pedalling.
I really love it. It's the oldest "turn your road bike into a tri bike" cheap trick but I can definitely feel I am putting more power into my ride now. I am also much more relaxed in my upper body position as I'm no longer reaching forward for the aero bars. I'm simply "hanging" on top of them now so I am in a more slack upper body state.
