Speed Racer: Giro Bike Helmet Reduces Drag, Slices through Air

It debuted at the Tour de France last summer. This spring, Giro offers its new-generation aerodynamic helmet to the cycling masses.

(See additional images of the Giro Air Attack helmet line on this page.)

Called the Air Attack, Giro touts “free speed” gains with the aero design. Two main models — the Air Attack ($200) and Air Attack Shield ($240) — provide a unique cut-through-the-wind dome design that Giro cites has the lowest air drag of any road-type helmet tested.

Air Attack Shield

We have the Air Attack helmets in house at GearJunkie and are currently putting them through some paces. So far we love the close fit and “speed racer” look and performance of the Shield model.

Stay tuned for our full review later this month. Below and on page 2 of this post is a look at the full Air Attack line, from studio shots to a peek inside Giro R&D where the helmets were tweaked and refined in wind tunnel tests. —Stephen Regenold

Giro is on the prowl this season. Making big moves all over. I bet we see more helmets like this in the following years.

Hey Gear Junkie. I work with folks with TBI. I would love to win this helmet for biking head protection, because I have seen how TBI can totally change someone’s life. Thanks for the chance to win. Thumbs Up to Gear Junkies Everywhere!

I need this helmet because I don’t have a helmet and father recently moving to San Diego I not only need a helmet, but one that will help shave any seconds I can when I do my first (of many) triathlon in a couple weeks. And with the price of competing I can’t afford to buy it myself!

Posted by Miguel Moita - 05/17/2013 08:07 AM

Hello! This helmet would be perfect for my commuting needs, by now i commute for work everyday but i don’t have a helmet…

Posted by Mike Barnett - 05/17/2013 08:09 AM

What a great looking helmet! I’d love to win one because, well, a helmet of that high quality would inspire me to get out on my bike far more often than I do right now. Yep: sometimes it takes a cool piece of gear to motivate me, and I’ve hit that point in my life where I either have to become far more active, or I’d better start shopping for an assisted living facility for my retirement years!

Posted by Rene - 05/17/2013 08:18 AM

Hi! Thanks for the review. I like to ride fast – and its seems like this helmet stands right between riding fast and well not so fast…

Anyways i like the helmet and hopefully i will wear in on my next TT :-)

Posted by Paul Bronkhorst - 05/17/2013 08:25 AM

I would love this helmet for 24 Hours of Booty, a cancer fundraising ride in Charlotte NC this July. I have a goal of riding 300 miles in 24 hours, and every little advantage helps!

Posted by Adam Goldstein - 05/17/2013 08:30 AM

Love the look of this futuristic lid! I would be honored to wear it for my upcoming 70.3s and for the crown jewel of my season Ironman Tahoe. It’ll shave at least an hour off by bike, right???

Posted by Ed - 05/17/2013 08:33 AM

I’ve just got to have this for when I do John O’Groats to Lands End (the length of Great Britain)this summer. If this can’t shave a few minutes off I don’t know what will (well maybe a bit more training) not to mention making me look much more pro than I ever really will be.

I’m a devoted road cyclist who discovered the joy of riding after a head injury (TBI) due to a rock climbing accident. I love my bike but I love my brain even more and this helmet would replace the old and decrepit brain bucked that i’m currently riding with.

Posted by Dustin Hinton - 05/17/2013 09:07 AM

I would love to get a good helmet… I have been on a mission for the last 2 years. Last year I went from couch to full Ironman within 1 year, and did every race distance in between that along the way 5k, 10k, 13.1, 26.2, sprint, olympic, (4X) 70.3, and Ironman Louisville 140.6. I went from 220lbs to 165lbs. I am a single dad of a 5 year old son, names Boston, with zero family within 1,000 miles from me, I traded a washing machine and dryer to get my old solid steel road bike and part of the deal included his wife’s old helmet from 2003. It has four holes drilled in it that a mirror used to mount to… I’m super broke, but super motivated.. I am taking on my second full Ironman at the North American Championships in Mont-Tremblant, Quebec CN. I still have the same old bike and helmet (that has taken me over 13k+ miles so far)… I could REALLY use a nice helmet. I would gladly take it. But if you find someone that needs it more by all means pay it forward because I do at least have a functioning helmet.

Posted by William Eddy - 05/17/2013 09:07 AM

I NEED this helmet because no tail is the new tail. I NEED this because everything else on my TT setup is old, old aluminum frame, old early 90’s Specialized tri spoke wheels, and this helmet would announce to competitors that I’m serious. I NEED this because in spite of my old TT gear, and or perhaps because of it, I can throw down a pretty decent TT. I NEED this because I have to wear glasses, and a build-in visor would let me see my next TT or TRI through wide eyes. I NEED this because I’d promise to do no less than 5 trials of this helmet vs the Giro Advantage 2 on the same course, and let you know of my results. You NEED me to have this so that there can be no excuses when the Gear Junkie Adventure Race teams beat up on my team at the next adventure race. I NEED this because I’m getting married in a week, and we will be posing for photos on our bikes. This helmet would really pull together our wedding attire.

Love it WIN IT!

I totally need the speed racer helmet for my race at IM Canada, Whistler!!!! I am fast now…but I would be ROCKET FAST with this radically engineered, aerodynamic piece of shear awesome on my head!

Posted by Robert Kaschner - 05/17/2013 10:57 AM

I need this helmet to protect my head and eyes. I want the helmet because it’s awesome.

Posted by rhoni4 - 05/17/2013 11:57 AM

I would love this helmet to protect me on my rides. I love that it has a eye shield so you don’t have to wear glasses.

Posted by Tim Rice - 05/17/2013 12:10 PM

I need.. because I am riding for two causes.
1. to beat late stage lyme disease. 2. To ride for Charity in July (Alzeihmer’s association, United rehabilitation Services, South Community behavior healthcare, and Juvenile Diabetes Research foundation) My issues I Piled up my road bike Last week in April folding the frame and breaking my Giro in 7 places. I am working on selling my car to replace me bicycle and still in need of a helmet. And honestly I really want this helmet so I can at least look fast until I get rid of any lasting lyme effects.
Oh and I need, because I know that Giro saves lives.

Posted by Steve Langenderfer - 05/17/2013 01:50 PM

I would love to surprise my wife with this helmet. She is signed up for her first Ironman this summer. It would be so helpful for her to have a sweet aero helmet like this!

Posted by Stephen Bullard - 05/17/2013 02:25 PM

I would suck less with this helmet…

Posted by Chris Welsch - 05/17/2013 02:53 PM

On a purely pragmatic level, I need this helmet because I live in Paris and I ride in heavy traffic. On the level of haute couture, I’m a nearly 50-year-old American from Nebraska who needs a little elan et elegance to complement my chops.

Posted by Josh - 05/17/2013 04:15 PM

I need this helmet because I love my brain and I need to keep Racer X off my tail.

Posted by Dale l Sutton - 05/17/2013 08:48 PM

I sure could get my head around wearing my new Giro bike helmet. The way I can slices and dices my way threw the air and the competition makes me a winner just by strapping it on my head.

Posted by chris - 05/18/2013 10:23 AM

Just want it. Thats all

Posted by Craig Porzondek - 05/18/2013 10:31 AM

Just had a friend hit from behind not wearing a helmet… now at U of Michigan hospital for extensive care… yeah get the helmet be a dork!

Posted by christian barra - 05/18/2013 11:04 AM

it’s really nice helmet, can be mine if you want guys¡¡¡ you can send me the helmet down to chile.

Posted by Pedro Kozlakowski - 05/18/2013 11:13 AM

I ride to the university every day. It’s a 20km ride till I get there. I usuallly get late, so this helmet would definitely help me arrive in time : )
And it looks fantastic, by the way.

Posted by Dave Adlard - 05/18/2013 11:57 AM

Nice helmet! Good article! I REALLY need one of these – while setting the expedition Idaho course with Mike Kloser, endo’d the bike down the mountain, landed square on my head, cracked/dented my current lid, making it the 2nd busted helmet in a year – still using it… yikes!

Posted by Michael Brouillette - 05/18/2013 01:34 PM

I don’t just want a Helmet! I need a Giro Helmet! I wear One Skiing, and Need one for Biking. Some Low Life actually stole my Helmet off my Bike when I went into the Store. I suffered a tramatic Brain Injury in March of 2003 because I was Stupid and Not wearing my Motorcycle Helmet (It Wasn’t COOL) I won’t ever go Riding without my Helmet on again..

Posted by Jan Warner - 05/19/2013 09:00 PM

I need this helmet because I go biking everyday and don’t wear a helmet. I haven’t found a helmet that feels right on my head but I’m sure hitting the ground won’t feel good on my head either. :) This would be awesome! I’m not a bike racer, just a casual biker who rides 6-8 miles a day because it’s great exercise and I love being outside.

Posted by George - 05/22/2013 09:59 AM

Honestly, I’m not sure I’m cool enough for this helmet. I’m gonna have to up my whole game if I’m gonna roll with a lid like this. You know what, maybe that’s exactly what I need.

Posted by Lars Erickson - 06/04/2013 10:52 AM

Honestly I just want this helmet to look cool when I walk around town..:) I consider myself to be somewhat of a trend setter:) hahaa

Posted by Brian - 06/04/2013 10:53 AM

The air is always beating me up, I need an Air Attack to fight back agains AIR!

Posted by Clinton Munkres - 06/04/2013 10:55 AM

I need this helmet because Head + Concrete = Bad. Head + Helmet + Concrete = Less Bad.

Posted by Jody - 06/04/2013 10:59 AM

I need this because I look like Alien in my current helmet. Big head, little body.

Posted by Amy Perkins - 06/04/2013 10:59 AM

I need this because the next time a tornado rips through my town, at least my head will be aero-dynamic. Well, that and I need it when I ride too. :)

Posted by Gareth Hughes - 06/04/2013 10:59 AM

because it may save my life one day….everyone should wear a helmet when on their bike!

Posted by Andrew Dolson - 06/04/2013 11:00 AM

Nothing, but nothing, about me cuts through the air—I really need the aerodynamic breakthrough.

Posted by Alan Dao - 06/04/2013 11:00 AM

I need this helmet because it is the best looking one on the market, and everyone knows that when it comes to gear, after performance, aesthetics is everything.

Posted by Brian Charles - 06/04/2013 11:04 AM

one reason…to look superfly while protecting my 43yr old chrome dome!

Posted by Timothy - 06/04/2013 11:09 AM

The helmet I am currently using is compromised. My friend dumped his bike while wearing it and the helmet now has a visible fracture in the foam. I continue to use it because of the “better than nothing” principle. Money is too tight to get anything other than a Walmart special. So do I “need” this helmet? No, but it sure would be comforting to have a new one and this would look pretty awesome protecting my melon while I’m burning up asphalt and dodging cars on my road bike!

Posted by Jack Lambert - 06/04/2013 11:11 AM

Performance. This bad boy has the lightness, the venting, and the protection we all need. Sexy. Who doesn’t want to look like Speed Racer while they complete their personal best time in that next race? Options. Visor up or visor down? Red on black or blue on white, etc? So. Many. Options.

Posted by Scott H - 06/04/2013 11:17 AM

With hurricane season approaching on the Gulf of Mexico, I’m in the market for a wind-defying helmet to protect the ‘light in the attic’ during the storm. With my old helmet, it’s much too easy to pull a Mary Poppins and fly over the house when the wind starts blowing. With this helmet – problem solved. And I can’t forget the attached visor, which is much classier than sporting a pair of tenth-grade science lab goggles when the debris starts flying. Then, when the storm is gone, it’s time to hop on the bike and get back to training.

Posted by Bill B - 06/04/2013 11:18 AM

I NEED this helmet to replace the several year old cheap bargain bin helmet I’ve been using with something more aerodynamic for my upcoming triathlon.

Posted by Ryan - 06/04/2013 11:19 AM

I need this helmet to protect roads, trees, rocks, vehicles, buildings, wildlife, and other potential obstacles from the powerful impact force of my head.

Posted by Ryan L - 06/04/2013 11:24 AM

I would love this technologically advanced helmet to protect my dome.

Posted by Jason L - 06/04/2013 11:40 AM

Because at the end of the day after whatever distance was covered and at whatever pace it was done at, no matter how tired you are, that helmet seems to speak like a small excited child saying: “LET’S DO THAT AGAIN!” And you of course cannot squash the poor kids excitement, so back out the door you go…

Posted by Dana Clark - 06/04/2013 11:49 AM

I would love to win this for my guy. He’s a great athlete but accidents tend to happen to him. From a busted collarbone to busted ribs to having a car hit him throwing him into the windshield. I know the helmet can’t help the rest of his body but at least his noggin will remain intact!

Posted by Markemmanuel Rodriguez - 06/04/2013 11:59 AM

I’d like to attack the asphalt and gravel while riding hard, fast, and light with this helmet. Plus, the Giro Air Attack Shield will make me look ridiculously good (even sexy maybe) doing it.

Posted by Paul - 06/04/2013 12:08 PM

I need this helmet for 2 reasons.
1. Zombie protection
2. Complete my TRON costume.

Posted by Kirk - 06/04/2013 12:09 PM

I’d love to have this helmet for my first IM 70.3 this coming august. I may not get the fastest bike split out there, but probably the most memorable one- just thinking of all the other triathletes who’d slow down just to get a second look at that slick lid!

Posted by Pascual - 06/04/2013 12:29 PM

i am speed! just like in cars movie but well lets be realistic, i’m not, maybe this helmet can help me achieve the “i am speed scene” but with a bike!


Posted by Adam lloyd - 06/04/2013 03:41 PM

That’s the sort of helmet I could go fell running in

Posted by Sam - 06/04/2013 04:29 PM

I need this helmet because i am in love with it and you wouldn’t want to deny true love would you? also, my dads blind stoker(back seat rider on a tandem) needs a new helmet for when they do iron man Texas next year, I’d love to surprise them with one of these!

Posted by Brian Jennison - 06/04/2013 05:27 PM

I’ll be attempting my first Ironman this year in Madison, Wisconsin. I’m a bigger guy and could really use a more aerodynamic helmet to reduce drag during the bike which would make it a slight bit easier and leave my legs a little fresher for the marathon. I was planning on buying a new helmet anyway and if I were picked I would still buy a helmet but donate it to St. Louis Bicycle Works. :http://www.bworks.org/bikeworks/

Posted by Dave Nguyen - 06/04/2013 06:23 PM

Because NASA won’t hire me to go to the moon

Posted by Jason Hardesty - 06/05/2013 09:28 AM

SUPPOSITORY”, to get right to the point. My best friend Brian has recently started doing Iron Man & other serious races and wears one of those dang old school Aero helmets. I can’t let my best bro continue looking a human suppository, ( all be it, a very quick suppository or should I say “fast acting…hahaha…ahem”) Anyway I’m afraid he’ll be single for the rest of his life so please, SAVE BRIAN!

Hello! Gear Junkie’s amazing reviews of products continue to intrigue enthusiasts of all sports. Cycling, however, holds a special place in my heart. Being a two-job, full-time college student prevents me from allotting funds to purchase adequate cycling gear. My first velodrome bike is under construction and I had my eye on the pricey CASCO helmet that is ubiquitous on the velodrome. Your preview of this product has my full attention and I await it’s full review. So far, it seems to match my personal style, desired function, and (most importantly), my budget. Thanks for the great work!

Posted by stephen gillman - 06/05/2013 01:29 PM

I need this helmet as I need a new one and all the components on my bike are worn so I don’t have any money left for a good helmet.

Posted by Dan S. - 06/05/2013 08:06 PM

I have a lot of holes in my head and while the Mythbusters proved the golfball effect improves efficiency, I think having a slick helmet will not only give me some better street cred during alley cats it might also prevent me from more holes in my noggin. If it’s good enough for the Tour of France then it should be good for the little tours of whatever town I happen to be racing in. Plus who would like to look like a Star Wars action figure on a bike. I know my rides would include laser blaster sound effects…
