Ex is spot on. There is a delicate balance between aero/power. If you can find a fitter that also has an eye for aerodynamics, or is at least aware of the influence of it, you can benefit from it. But it's all experience and guesswork until you test it. When I have spent time with Cobb at the ATM tunnel he spends a fair amount of time making sure the rider can make good power in a position (on a trainer with power) before even sending them into the tunnel.
i realize i may not be able to get this tested (and take the point that nothing is certain until tested), but the right fitter may have some better ideas about what might get me pretty close.
i was hoping to find somewhere within 5-6h of drive time.
thanks!

What about the new carbon fiber bearings that have less drag than ceramic bearings? Lighter, too. Under electron microscopes you can see that their surface is comprised of Buckyballs.

great thread.
I still think the power meter is the OP's greatest tool. I have thrown an allen wrench in my pocket more than once and adjusted spacers during long rides to see if I could find more power (measured against RPE). I was able to find a sweet spot between comfort and aero doing this without much trouble.
Interesting enough when I am playing "how low can you go" there is a point where my power output drops dramatically if I go to low. Seems my body uses a lot of energy trying to move my gut out of the way. ;-)

I think the nanotech carbon fiber ceramic coated dimpled microbearings for the headset bearings are going to be a bigger deal.
