Also, pointedly, there are a lot of Cervelo riders around here (on the forum and in my area). Not one of them has said "wow I can't wait until I get change to a better bike than this POS". Most have had a string of Cervelos; those that have bought others bought others for specific reasons (gravel before the Aspero, for example, or specific tri features).

I wonder if he wasn’t wrenching on the cockpit and just didn’t have his final position set yet.

The irony of this in the context of some dude ****-talking the engineers of Cervelo and Cannondale is priceless. Having a YT channel doesn't mean you know a damn thing.

Damon Rinard was chief engineer at Cervelo for several years before moving to Cannondale. I believe he's responsible for the S5 and SystemSix (not that they have anything in common).

In other news, I rode my P2 last night for the first time in a while and was once again amazed at what a fine machine it is. It is certainly better than the very-good R2. No creaks from either.

Well, Hambini still has his Cervelo so he can't think it is all bad!

You guys are being harsh. Wasn't Hambini one of first persons who analyzed wheel wind resistance by considering various wind offsets while everyone else assumed a static, head on wind?

The drop bars are in an old/outdated position, yes.
But look at the other bike he pulls out- it has modern compact drops and the bars as well as shifters are in a good position.
Odd.

And Hambini hasnt "analysed" anything. I suspect his aero wind tunnel test was a big fake - not a single photo to even show the tests were done or even showing all the wheels, and when challenged, he made up a sock puppet account on ST masquerading as his colleague and that awful fake "cease and desist" letter purportedly from Flo's lawyers. THAT is the guy people have so much faith in?
What Hambini did do is just bring up the issue of transient winds - ie, point out that wind conditions when we ride are not constant - umm, ok. Pointing out that a lab test is not exactly the same as the real world is not particularly earth-shattering. It's like people who say "well, riding on drum tests is not the same as riding on the road". In both cases, the differences between a controlled setting and a real world setting dont mean that the lessons from one do not apply to the other.
In practice - the entire industry (manufacturers, testers, race teams) have used the results of wind tunnel testing to predict performance on the road. i think it is safe to assume that top aerodynamic experts are aware of transient wind conditions (it's fairly obvious) - SwissSide refers to it in their testing too. So again, on one hand you have an industry populated with experts who get paid to demonstrate their expertise. On the other hand, you have a guy with a Youtube channel who throws out a few facts/buzzwords - enough to make himself sound informed to people who don't know any better. But he curses, so that makes him genuine/a guy who tells it "like it is".
I get calling out the actions of a particular company. But when multiple, independent experts - many of whom are competing with others and have a vested interested in doing a better job - all tend to gravitate towards the same process and methodology, that should tell you something. Occam had something to say about this.

I feel sorry for people who watch one of his long-ass videos and think it means anything. They are all the same, as well.
I do think he is right about the frames sent in to him, and that BB issues on carbon frames do arise. However, I think it was the Canyon video when at one point he claimed "and I have hundreds more examples" (this was about voids in the frame, where we don't even know if more voids is really that bad). No, he doesn't. He only ever gets sent the bad apples, and we have no idea if for every bad apple there are 10, 50, 100, 500, 1000 good ones. He just makes it appear it is only 10 or so.

I bet he hasn't done 100 frames total, let alone 100 Canyon frames specifically. Even these "bad apple" frames he is sent, there is no correlation to frame voids and finishing issues with bottom bracket holes or anything else. He is obviously a smart guy but now the problem has become that he has created an ecosystem of cause and effect, which has no basis in reality. I do like his videos and it is interesting to see him get BBs fitted too bikes properly but he really should stop x-raying frames. It's not doing anything for anyone.

Here is the problem with what he does though. The frames being sent in have some sort of BB issue. OK fine. He x-rays the frame then says "the owner couldn't get the BB in so he sent it to me, and I x-rayed the frame and it has so many voids that I wouldn't ride it".

For my personal elucidation, is that also reflective of a trend of riding on the hoods more? I can't imagine how you would ride with handlebars and levers set up like that aside from staying in the drops.

Dont introduce visual evidence to support your comment, this is bike forums where trends are embraced and then quickly ignored and denied as having existed!

Someone like luescher teknik is different in that they are a carbon repair shop, so I assume they see lots of bikes. When he agrees with something someone like Hambini says, I give it more credence.
Voids are bad - which is why they try to minimize them. I ride with a person who had a cracked top tube (right behind head tube) for over 3 years without issue. This is a lady that was <130 lbs so that might have contributed and carbon just blows apart spectacularly in other situations. Around me, there are lots of people riding gorgeous Andersons, Speedvagen, and Lynskeys because they 1) have money and 2) had issues with carbon bikes.

At the very least, it is exceedingly unfair to the manufacturers whose bikes are being slandered because, among other reasons, Hambini got into a hissy fit after one of their founders disagreed with him on Slowtwitch.
