Seat not too high. Body is quiet and relaxed looking through the pedal stroke. Looks comfy.

There are a lot of aero gains on the table. But I'd call it a good starting point.

 
Feel free to expatiate. Input on aero, too is appreciated.

I just mean that you're presenting a good amount of frontal area to the wind. Your head is held pretty high. Pad stack is pretty high. You look like you may have broad shoulders (though hard to tell from the angle). But that's from my perspective as a pure 40K TTer. What you have there may be perfectly fine for triathlon. I'd be loathe to suggest something that may end up being less effective overall.

I'd say that stack is too high. The wind has a lot of surface area to eat up like a sail. Try to get your back as close to parallel to your top tube while still comfortable

Saddle is a touch too high. Drop it 5-10 mm.

Cockpit needs to be lowered about 3 cm and armpads/extensions need to be moved forward about 3-4 cm to stretch you out.

It's an okay "bike shop position", but not really a good fit.

Gotta say, I think those are good suggestions for getting closer to optimal. But I know some smart and experienced people will disagree... ;)

Mick, what changed between this fit and your old one? What feels better about this fit?

I was much lower in the front (625 Pad y).
The reach was 500 (Pad x).

But the saddle was 80 behind the bb. And I always felt like I could not apply good enough power. Moving the saddle forward would result in me feeling even more squeezed with the Pad x going down. I sold the bike 3 years ago and only now (after injury) decided to give it a another shot.

  
Will be travelling on business for the week. Will make adjustments next weekend and will repost.

So you moved the saddle forward (how much?), kept the same pad x, and increased pad y by 90mm. Saddle height the same?

Did you try a longer stem on your old bike? That should have allowed you to move the saddle forward and still have good reach.

Bump for input on the changes made.

I think you require a -17 stem

This. You look like you can come down more than what you have, but also your posture isn't very good. Need to drop your head more and look up through your brow. The lid you have on is probably making that imposible as you'd be looking straight into it and see nothing at that point. Try using a dedicated TT helmet with a visor and clocking it as far back as your able. This should help with your head position. Really, that's the hateful thing here. but less pad stack, if you can go with less pad stack I would.

my original thought is that his bike is too small as well... he could have sized up and gone with a low profile basebar/extension system.

Really, really good. Could drop the cockpit another 1 cm or so - as others pointed out a -17 stem would do the trick and would look awesome too.

Installed the 17 degrees stem (it does look very nice) and set the saddle back a bit.
Saddle is now 19mm behind bb.
Pad Y: 665
Pad X: 529

Your feedback is highly appreciated as I am dialing in my fit.

Looks good! Have you or can you mess around with head position? Is that the helmet you will race ?

 
Yes, I see what you mean with the head position. Certainly something I can play with. I actually did try a few different positions during a road test yesterday. I also will have to build the muscles in the neck again as I hadn't ridden a tri bike in a few years.
The helmet is what I am planning to use in races. It is a Giro Vanquish with the integrated shield.

It could be that you need to raise your stack a little bit more to help you get a little better shrug and get your head out of the wind. Obviously try at your current height but after some training if you feel like it's just not working raising it up could ultimately still be faster if the end result is a better head position.
