Unless you're getting significantly slower every single day, this just isn't true. And unless you have the very best gear, you're better off buying the gear, getting fit for aerodynamics and gaining an additional 10lbs.

Yes. Not yet in North America, but in other areas.

If you are a triathlete that is a very annoying helmet for long distance....great for TT.s but not much faster than the previous giro .

We’ll definitely test it, but I’ve heard it’s all bark and no bite. Not really that great.

@@fastorfictionHi Jim I have the Lazer Volante helmet, would be great if it’s tested by you when having the time

😂😃

Pros use what they’re paid to use. Never forget they’re contractually obligated to say positive things about the products they use.

They test at their race pace. All are front of the pack athletes so 25mph/40kph and above. Christina about 22mph.

Wrong.....the color do not play any roll....there is a venturi effect that keeps the air moving at great speed inside...also you have an inch thick of polyurethane in between the fast air moving outside and the air moving by venturi inside....I participated in the design...only in mountain bike where speeds are minimal the color plays a roll...you guys should not treat people who spend countless hours working on physics as "stoopeed".

@@daniellagrimaldi Major issues with your reply: First, the basics: 1) The impact of heat is based on transfer of energy from object a to object b. In other words, heat is a transfer of energy. Less transfer, more energy absorbed/kept. And, vice versa. 2) Venturi Effect, is a change in velocity of a fluid or gas. The increased speed of air causes a decrease in pressure and this decreases pressure resulting in a drop in temperature. Second, using these principals, this is the explanation why black helmet would not be the best color. 1) White color absorbs LESS energy/heat. Black color absorbs MORE energy/heat. So, you have a higher ambient temperature surrounding the surface for the black color. This is why a black surface will melt ice faster. For example, if you have a 25C black color you might have a 22c white temperature. So you have a higher initial ambient temperature. 2) Passive cooling using the Venturi effect for both colors is the same and would result in the same capacity to create a lower temperature. Lets assume that drop is 2c for both. So, for example, the higher black temperature 25c would drop to 23c while the white at 22c would go to 20c. The net results is the black color will always be hotter because it absorbs more energy. The only way this can change is if the black object/helmet had different qualities and design to compensate of more absorb energy caused by the dark color. HOWEVER, the helmets are insulated equally. And, the insulation prevents most of the heat transfer to the head. But, the ambient air inside the helmet will be warmer in a dark helmet. How much this effects the internal temperature of the helmet varies based on the how much air is trapped in "air pockets" within the helmet. It is conceivable that this could be offset by passive cooling with air flow. But, the key point is why start from a warmer ambient temperature with black in the first place when all you need is a white helmet to begin with. The reason they make black helmets is because they don't show dirt as easily and some people like dark colored helmets. But, there is no other justification.

​@@daniellagrimaldi Apparently someone didn't like my rebuttal... and deleted the detailed explanation of why the physics says differently. Or, perhaps I can't see the reply. At any rate, the short answer is this: Black helmets absorb more heat than light-colored ones, creating hotter internal air pockets. This means any cooling airflow starts at a HIGHER baseline temperature than in light-colored helmets. While insulation will block heat from reaching the head, it does not remove the fact that black helmets inherently start with hotter internal air pockets and limits the impact of the Venturi Effect. Black plastic is CHEAPER to make and buy. Black helmets show less dirt and some like darker colors. That is the limit of their value.

And $700 kits…get used to it I think. I bet other helmets will be more

Given the amount of R&D goes into these and the numbers they sell, it's not as surprising.

The Aerohead Ultimate was used by several athletes in Paris who had access to the new Giro but chose it instead. It won a gold medal. The vented version sold to the public isn’t a top helmet anymore, but the Ultimate, no longer publicly available, is still relevant. We tested the TT5 in a previous video. It was overshadowed by the Kask Mistral (a difficult helmet to beat) and is really only good when your head is held in the perfect position.

I suspect most of us would like to see a test vs the Aerohead 2 rather than the Aerohead

Comparing to the aerohead is useful since a lot of triathletes (age groupers) still use it.

@@fastorfiction so, are you saying that the rudy wingdream is likely faster for most than the TT5? - great vids! just found you and subscribed!

The Giro really interests me because I’ve heard mixed rumors on its performance. I noted several athletes who had access to it for Paris instead chose the older Aerohead Ultimate. Can’t wait to test it.

No plans. That helmet is great when you keep your head in the perfect pain, but the moment you move it, it’s no good. It tests well in a tunnel, but rarely does it work in the real world. It’s an old design people had given up on because it wasn’t fast for this reason. It only came back because I’d the Huub track guys (one of whom was my client) used them for pursuit. For a short event like that, it can be quite good.

@@fastorfictionWould you say this would perform okay when not in the position during a triathlon event?

@@thenoclue90 I don’t think any aero helmet would perform as intended out of the aero position, but I guess it depends on what you’re comparing it to.

​@@jtmanton many triathletes with more upright positions than road cyclists have done testing and found that TT helmets are still faster. *I'd absolutely not want to wear one at road cycling speeds though, or even as a slower triathlete doing anything long unless it was a very cool day

We will definitely do something like this. I want consistent riders for this exact reason. 👍 Thanks!

Myself as well!

I've been waiting months for that video!!!

Someday.
