Hey, this is really interesting. I would like to hear your opinion on some of the other top guys' styles at some point if you can be bothered.
Bike position is a philosophical conversation and not one of science.
Too many bikefit studios opening up with knobheads putting average Joes into the 'postman' position.
Frustrating.
Often I tell people to think if you had to build a robotic legs and a robot and attach them to a bike - how would you design them?
You'd have full range or motion in the hip joint that would allow the knee and ankle to freely move up and down. If it were a robot it couldn't kick it's leg to one side like a human can to accommodate the tight angle in the hip. You see too many cyclists from behind kicking a legs to the side on the up stroke so they can accommodate the poor angles in the hips. Open up the hips, allow the leg full range of motion and 98% of the position will come from there.
Bikefit studios which place sensors on you and then depict you as a stick figure assist this process.
The next part is stem length. Way too many cyclists sit too upright. Now some have to as they have poor flexibility. But you should look to relax over a nice stem length to the hoods. Allow yourself to still reach the drops.
But get the hips right. The biggest crime in bike fit is treating your bike like a couch. Trying to make it comfortable. Wrong. You need to make it right in terms of power and then the comfort will follow.
Get a photo of yourself from the side and the front. Draw lines down your body and measure the angles in the hips and between your upper arm and chest. Your answers will lie there. Front on draw a line from your eyes down through your knew to the front of your foot. The next answer will lie there. Your knees should track in a line. Watch Andy Shleck climb. Look at his knees. Perfect. You knees should point from your hip slightly inwards towards the top tube. It's just the way a human body is shaped. Too many cyclists with knees that point out. Wrong.
The last problem with bikefit studios is vibration. The road vibrates through your bike. The bike and your body absorb the vibration. You need to build virtual suspension for this process. Bikefit studios get you in a very ridge position that doesn't accommodate the fact you your bike is rarely up right and stationary. It's actually moving around a hell of a lot.
It's all very hard to get right on your own. You just can't see yourself. You need someone to film you.
Edit: Someone above mentioned Frank Vandebroucke. Model yourself on him. Perfect position.
