By the way, before any smartasses unload on me for gearing up for a garage spin, this was after a ride. Thus the headband, arm warmers and shades.
Saddle looks too high.
Here’s my “road” aero position.
I love that Colnago. Absolutely beautiful bike. Just a question for you though, why the clip-ons on such a beautiful road machine?
Do your shoulders or upper-middle back get fatigued after 60-80 miles?
Are you stronger on your road bike?
TT position looks good to me…but then again I don’t know much!! : ) I ride with a very high saddle position. Th saddle is set to my long left leg (37" inseam) and its about 1" too long on the right. But all the bike fitters that look at my position always say…if it works…leave it alone!! I’ve adapted to a “toe down” position on my short right side to make up for it. Been like that since 1980.
All I can add is…please clean the tool bench…!! : )
Looks pretty solid but have you tried going even a little lower in front? Maybe try taking out a spacer but your position seems good enough that I wouldn’t hesitate to put the spacer back if you find you can’t generate the same power or if you aren’t comfortable.

Dude, 60-80? Longest is 55 miles so far. Neck was extremely sore after 30 or so.
As for other questions…
…the aero bars are on the road bike because I want to ride aero (even if nowhere near as low) as much as possible. That position is pretty comfy.
…I actually raised my position on the Cervelo about 1cm to get to this point. It was just too darn low before. Even at this height, I really struggle to generate the same watts as on my road bike (which, by the way, I seem stronger on the aero bars than on the hoods). I also just don’t have the neck structure to be that low in the front.
looks to me like you are dropping your elbow and need to rotate the hips more to engage your kick…
oops, wrong discipline!
Your “road” position looks much more powerful and relaxed. Are you a Long-leg Craig? Don’t appear to be based on the photos, but maybe you’re more suited to more of a road position.
I like the black and white Cervelo, a lot like my P2.
stick with hockey

take those cheap clip ons off the colnago - now!
At first glance they look not bad, about the same as my photos on my Cervelo and Lemond OCLV/steel, but can’t tell unless I measured angles with the protractor. Better still would to come over to your place with my tape measure and ganiometer. But it would cost you a beer.
It seems like your camera may not be centered perfectly which would effect the photo measurements. Can’t do them tonight since we’ve got company. Will try to give a shot tomorrow if possible.
bring in that cockpit on your tri-bike, you look very extended, thus the neck pains, etc.

Actually, you make a good point there. Are there any more expensive clip ons I could add?

I am actually a bit short in the femurs, though my total leg length is about normal/average. I actually would’ve picked a smaller frame to get a shorter top tube, but then I’d be way over the spacers-under-the-stem limit.
The black is custom – couldn’t stand the blue/white P2K colors.
To the poster mentioning the shorter cockpit… this is with an 8cm stem already. Can’t git no shorter without a shorter top tube. But I have to say, it feels pretty short already.
And I am indeed more relaxed and powerful, at least so far, in the “road aero” position. But keep in mind I only have a few hours in the tri aero position.
I would flip the stem to get lower. this would in turn get your elbows a tad closer and your arms more at 90 degrees.
I would also shorten these bars a tad and lower the seat a tad.
You have any back problems on either bike after a couple of hours in the bars?
