Help! I need specific adjustments...

[adkoch]

This is my very first post - I am grateful to have found this site!!! I am considering commuting to work (~15 miles one-way) and cannot wait for Spring! I got my road bike out for the first time of the season on Saturday to try out my new route. I was out for about an hour and a half (many wrong turns later!) and noticed the same old problems that I've had the last two years with this bike/saddle/aero bars combination: First, I have my seat (Terry Butterfly) positioned in a slight downward position to alleviate the extreme pubis pressure otherwise, but now can no longer feel my sitbones in contact with the seat and feel myself sliding forward. Since I am farther forward, I am no longer over the anatomical opening of the seat. Secondly, my elbows, not my forearms, are what is resting on the pads of my aerobars, which is irritating and jarring. Lastly, it seems that my aerobars aren't long enough, as I have to pull my wrists back in order to effectively grasp the bars, instead of the hands being in more of a straight line/extension of my forearms. However, the aeros have only an inch left of give before falling off! I despirately need help and realize a fitting may be in order, but don't the shops only do that if you're buying a new bike? I know how to make many of the minor adjustments myself, so in the interim, might you have any suggestions? Any advice is appreciated... thanks!
