I was just telling my buddy how I like some of the new unique designs like the TREK IsoFlow, Cervelo S5 stem, Seka and LaPierre and Pinarello seatstays. This is not going to make my personal list, good grief

In that case race bikes for the pros need to be seperate from normal road bikes. All those marginal gains come at a huge price and there is no point in the public being expected to buy these bikes. You don't buy a car with Formula 1 technology to take shopping do you. Making a car like that is just needless in every way.
That's a bit apples and oranges. Altough F1 cars are also way more over-regulated than any UCI sanctioned Bike or Event. But could also be way faster and saver than aynthing on the track atm. Lot's of good tech is straight out banned. And at the same time we have moved far away from the F1 from the last century, or even the 00 years. A move, like the one towards Hybrids in F1, is something so far off the scale, the UCI would not even once try to think about in a weak moment. Same goes for savety in general. I like the FIA as much (not) like the UCI, but they at least had the guts for several revolutions in the sport for the past 20 years.

Maybe ignoring UCI Events (and Rules) as a heritage/ vintage thing, and doing actual racing for the sake of development outside this bubble of yesteryear, would be the 1st step. Or just don't give a *f##k* about it in the first place. I never sold a single roadbike because of some UCI rider, team or event. People just wanna ride bikes.

Pointless gimmicks if you ask me.

What's the point of a bayonet fork if you're not even close to tube depth limit with the headtube. Just extra weight and complexity for no reason.

The seattube may be moved forward, but the angle is still so extreme that raising it adds massive amounts of setback/effective seat angle. Just worse than S5, Foil, etc. But hey it may at least give is some actual vertical compliance.

Pretty shallow bb area for an aero bike too.

The bayonet fork reduces the frontal area of the HT and also reduces the overall stack height of the stem in conjunction with the riser bars.
There are other ways of narrowing the ht and the other part is purely a negative when it forces a fully proprietary cockpit solution.
Nah it's pretty tough to get really thin without the bayonet fork. Look at the factor hanzo, which got the frontal area down to 15mm. When you reduce the width like that you need disproportionally more longitudinal length to keep the required stiffness/strength in lateral bending (e.g. like 50mm long in the case of the Hanzo). But if you want all that length to rotate inside a head tube, the head tube becomes outrageously wide just to contain it in any of the rotated orientations. Thus, the only real way to do it is to get the steerer outside the headtube. Then you can make it arbitrarily longer.

That said, from the images, I don't think they actually used the bayonet in this case to significantly reduce head tube width. So your original point stands.

Regarding the bike itself, this does indeed look like a mix of every possible aero feature from the last 10 years that they were able to brainstorm, all at once. Including the ones that have since been largely discarded. I don't have high hopes.

I do find two things interesting though,

1) I expect the Y shape bars to be better than the ones with a crossbar across the top, aerodynamically. Structurally, not 100% sure.
2) I expect really good vertical compliance at the saddle. Potential downside being it won't be very torsionally stiff around the top tube axis. Which will likely be OK for pros with a smooth pedal stroke, but may be pretty crazy for guys that throw their whole body around even while seated, etc.

I am also curious to these influx of v-shaped / y-shaped style of bars. Are they really faster? Visually I can see that it has less visible area looking at the front by foregoing most of the meaty headtube/ spacer stacks on normal aero bikes. But they don't seem to that much thinner/ have less material.

The best implementation of this approach i think is the cervelo s5 due to the flexibility of the adjustment. You can actually tilt the bar on the s5. They have lots of stem length and spacer options too.

To your point #2 there is quite a bit of side to side flex on the post area of my Madone Gen 7, but I only feel this on the trainer and with extremely exaggerated pedaling. In the real world I don't feel any flex in a negative way.

Not much room to insert the post on the Colnago, I wonder if there will be cutting required or they will have numerous extravagantly priced lengths to choose from

Can someone explain how or if this is actually more aero than a regular post? It's still got the seattube essentially the same length and size except some of it is pushed back.

Always keep in mind the way the race number will be attached to the bike.
It will be very different for different frame sizes but with this seatpost design you can maybe prepare the air before it hits the top part of the rear wheel

Looks like someone asked OpenAI to make a frame with the following inputs.....madone + look blade + cervelo S5.
Here's what the AI actually generated.....not quite as spot on. Maybe needed to add a few more details to make the Colnago in 5 mins

This is the real question. What's the point compared to a 3t Strada way of hugging the rear? Can only be comfort.

The frontend makes more sense as there's less frontal area but still we're talking exceedingly marginal gains here. At least the hose routing is smoother. Hopefully there are different rise options available to replace the role of spacers.

All those who talk of F1 can go watch triathlon. You get suitably wacko designs there. Not sure it makes the sport any more watchable though.

So which is better looking?

Bianchi Oltre or Colnago Y1Rs

I'm going colnago for me... But I'm very dubious over the colnago seat tube junction assembly
