You guys act like normal aero helmets and tights are completely normal, but this helmet is crossing the line, lol.

This is just the UCI being dumb about how they regulate their own sport. They published helmet guidelines last year, and the new Giro helmet ostensibly meets those guidelines. Now the UCI is going back and saying they need to take a closer look, because there's an online kerfuffle about a new helmet - perhaps they should have done that last year? I get that people can be creative and bend the rules, but surely give this time?

Put in a body that reviews helmet guidelines every x number of years (2? 3?). This should include safety as well as size/fairing specifications. In the meantime, let anything that meets the criteria proceed, and fine helmets which don't meet the guidelines. Review again in x years to see if your initial rules were creating the desired effect, and make subsequent rules take a certain time before the come into being, so if you change your guidelines, everyone knows 6 months or a year in advance. The only exception should be safety - if they find something unsafe, then you can convene a special task force to mandate safety features that come about.

At the end of the day, the last two meaningful tests against the clock were won by UAE. Juan Ayuso beat Ganna by a single second at Tirreno and McNulty, Vine et. al won the TTT at Paris Nice. In both cases, they were wearing "conventional" Met Drone Widebody helmets so can't help but wonder if all these POC Tempor inspired designs are actually faster in real world conditions.

Maybe Marcag can chime in, and maybe he can't, but Lionel using the POC and knowing he's gone into the tunnel and did velodrome testing with it, it will be interesting to see if he is actually using it come the first race of the year. I am sure part of the answer is ability to hold the position, so the majority of age groupers would probably test slower with a bigger helmet, but Lionel as been at least fooling around with the Tempur...and it might be the one that has been fastest for him.

Why do we never hear of the kask mistral in testing ?

Lionel tested a limited number of helmets on the road, but the Tempor tested fastest.
In the tunnel it was the fastest over an weighted average of yaw angles.
If he finds something faster between now and next race, I am sure he will wear it, but for now, it's the fastest he tested.

I also recently tested Sara Perez Sala and it did quite well for her. I am curious what she will wear at T100 Miami

What I think is crazy is we're what, 8 years, on from the aerohead being released and there has not been a helmet in that time frame that tends to come even as close as the aerohead for as many people/body shapes/positions across as many yaw angles/wind conditions.

Here is a question I haven’t seen asked yet, but it takes a little explaining. When I went back and looked at the TTT the one thing I noticed when watching Visma was that across the entire team their heads seem to bob around more than other teams. It occurs to me that extending the edges of the helmet farther away from the head exacerbates any movements of the head. Going back to trig class (sin theta = opposite/ hypotenuse) the front of the helmet that is 6 inches long will rise and fall twice as much as a helmet that extends 3 inches in front of the face.

So my questions are
1. Do you ever work with athletes to reduce head movement and if so do you see measurable differences?
2. What are the chances that there are CFD tools or wind tunnel protocols that can assess what I assume is a problem of flow separation from head movement?

When can I buy one of these?

Looks a bit like the front of a raptor drone

I'm still trolling various marketplaces waiting for some destitute former EF guy to put this helmet up for sale. And, yes, I'd 100% buy the new Lisa Bike Giro helmet.
