The aero positin takes a bit of getting used to. You'll have to experiment a bit to find the best angle. I have mine up about 15 deg. from horizontal, but I'm not competing or anything, that's just for comfort and a change of position, and a little extra speed. As you get used to them you'll probably have to change them again. I found this year I had to make some adjustments at the start of the year, as last years position didn't feel right.
