Giro Air Attack

[bura]

Ha, even the pros hate these new goofy helmets..

''The talk of the peloton is about these ridiculous “aero” helmets they’re making us wear. I mean … seriously? They always put them on the big name riders first and then they start trickling down to the rest of us. You’ll see Specialized’s new helmet on Boonen right now. They had a great looking helmet and now what what they’ve done? Scott, Lazer, Kask, Uvex … almost all of them have gone backwards. We’re now on these absolutely ridiculous looking Giro helmets now and every iteration is getting worse and worse. ''

When there is no story around the "secret pro" steps in.
One of the myths about the teams.
Let's say your team is sponsored by Giro you are free to wear either a "ridiculous" looking aero helmet or some Aeon.
What ever you wear please do not wear these dump black "sun glasses" of the secret pro in the link where you can see only with one eye.
What ever secret pros and lego playing guys write or think the Giro AA will find its way everywhere where cyclists can be seen.

Funny, sounds like we'll be seeing a greater proportion of these on self-sponsored riders than pros. At least for a while. My goofy Giro should be here tomorrow.

each to their own I spose

My medium came in a touch lighter at 280 grams even. 77 gram savings from the large Ionos I am downsizing from.

My German made aero road helmet in Size L is 291g(290 claimed), but with papers attached, so probably it's even lighter than claimed. Size M is 260g claimed. Your Giro's are boat anchors.

Kasparz, what helmet? Pictures?

Pick the Pro that isn't keen on Classics/flat roads

With minimum ventilation, I may pick up the Air Attack for CX racing. If the aero shaves off .001 watts, I will be happy by the 60-minute mark, lol.

[Kasparz]

It will save you more watts than your precious carbon wheels with Dugast tubs

[KWalker]

^no, it won't actually. The savings are minimal and assume that a rider has a relatively aero position to begin with. Where your head falls in line with/above/below your torso has a much greater affect on drag than this helmet. Switching from poor to good tires has a bigger effect. Even raising one's bars to reduce the frontal area of the arms has a greater affect.

I know quite a few riders on Giro-sponsored domestic pro teams. They wear the air attack because they're encouraged to do so when they can to satisfy their sponsor. So far this year they've done it in medium to cold weather when sweat isn't an issue. I've seen more unsponsored riders jazzed about this helmet than they are.

The ventilation is actually pretty good IME. It was 90F/32C out when I used it yesterday, and it seemed just as cool as my Ionos, without all of the wind buffeting I get with the latter. Cooling definitely improves the faster you go as air is forced through the helmet (this feels a little odd, but it works).

However this is the non-visor version -- I expect that the visor version would lose a lot of cooling since the visor blocks the air intakes below the brim. I note that I haven't seen many pros wearing the visor.

I am content with the cooling of the non-visor version and see no need to go back to skeletal helmets. Of course I may eat my words once it gets really hot here. We'll see.

Cat6TT: quick question because it related to the 'cooling' affect you are feeling... How much hair do you have on the top of your head? (In all honesty)

Just asking because I've read plenty of reviews in the press on helmets' cooling and venting, but all the testers seem to be bald (shaved to compensate for hair loss/thinning or already fully bald). Those of us with thicker lock of hair may feel less of that 'cooling effect' ?

I have noticed that the shield version has been seen in two different visor designs.
One version has some air intake holes in the shield

and the other has no air intake
here http://www.artscyclery.com/descpage-GAASH3.html
Not sure if the air intakes are for a clear visor or free the way for the air intake in front of the helmet as shown in the original Giro video on their website.
Let's wait and see which visor design the end product has.

[Cat6TT]

Ah, yes -- we will see.
