Choose carefully
By Jay from Atlanta, GA on 6/29/2009
Sizing:Feels true to size
Pros:Convenient back-of-head adjustment, Good ventilation, Lightweight

Describe Yourself:Avid Cyclist
Bottom Line:No, I would not recommend this to a friend
Comments about Giro Indicator Adult Cycling Helmet:

Helmet was working good until I had a slight fall
on a trail, hit my head with the helmet on.
Blacked out and got a concussion.
The helmet didn't give me much cushion between my
head and the ground. Fall was not even that bad.
I don't recommend for avid cyclists who ride difficult trails.

So, hold up, reviewer lives to ride another day and can type his/her review, but the helmet didn't do it's job?!?!?

Perhaps I might suggest that if one is going to have a "slight fall", and manage to hit his/her head hard enough to sustain a concussion, that cycling might not be their best choice of outdoor activity..... in fact, maybe they should stay on the couch..... with a well cushioned carpet on the floor in front of them. Yikes.

So you guys are saying that helmets aren't supposed to protect you against concussions? What exactly are they for then? It's funny that every time someone falls on their head with a helmet on, the assumption is that the injuries would have been much worse without it. Okay, sure, it must have absorbed SOME of the impact energy, but how much exactly? Is it okay if the helmet absorbs only 5 percent of the energy? How do you know if a helmet is doing its job unless you volunteer to land on your head once with a helmet on and once without? Otherwise, the amount of protection offered by helmets is somewhat speculative and the helmet worshippers will claim that surely your head would have exploded into a fine mist without it.

I'm only suggesting that if the fall was in fact "slight", a concussion should never have occurred.

If he/she racked his/her head hard enough to sustain a concussion, the helmet in fact did it's job. I'm quite certain that if this person were not wearing a helmet, and whacked their head hard enough to sustain a concussion, they would have sustained injuries that were much more severe.

Would a better helmet have prevented the concussion? Only one way to know for sure and I'm not going to be the volunteer. I've destroyed two helmets whilst using them for what they were designed for, and both times, the helmet came apart, my head did not. One of the episodes left me with a mild concussion. Without the helmet it's possible that I wouldn't be typing this message. Chevy vans are not as forgiving as they appear.

Safety nannies don't care about facts. All discussions must remain anecdotal.

For instance. Every person that falls with a helmet on would have died had they not been wearing the helmet. I mean, who does this guy think he is? The helmet SAVED HIS LIFE, and he's whining about being knocked out. Boo hoo...


Of course, both sides tend to forget the majority of the force is generated by the vertical drop. Your forward speed is largely inconsequential. Head-on into a car is another issue entirely, but no helmet - bicycle or motorcycle, is designed to protect against that kind of impact. Motorcycle helmets are tested by simulating drops from riding height. Think of how much more substantial they are than bike helmets.

I follow your logic, but I also believe that my head is important enough to me that it's worth $100 bucks every 3 years to mitigate even 5% of the damage of any fall I might sustain.

If a helmet were a royal inconvenience, or heavy, or dorky, or anything, I would understand. But it's not really, so I'll continue to wear one.

A helmet is not going to save you from a concussion caused by your brain sloshing in your skull when it suddenly stops moving when it hits the ground. It WILL prevent your skull bones from breaking apart when your head hits the ground, and/or your brains from splattering all over the place like a crushed watermelon if your head comes into contact with something hard and relatively sharp when you fall (curb, rocks, tree-limbs, etc.).

There are also concussions that occur for reasons other than direct impact. In these cases, a helmet is not likely to help you no matter how well it's constructed. I'll still assert that if the fall was in fact "slight" that this couldn't have happened.

"Rotational force is key in concussion. Punches in boxing deliver more rotational force to the head than impacts in sports such as American football, and boxing carries a higher risk of concussion than football"

As for whether I would be dead or not if I hadn't been wearing a helmet, no one including me, can ever prove that. I can only say that, upon examining my helmets after both events, I was glad that I was wearing one.

I also know that I rode like a lunatic as a teenager, and the thought of wearing a helmet never crossed my mind; I'm not even sure they were available back then. If you've ever been to Europe, you'll see many more people riding bikes without helmets than with them. Do what you want.

Man, you guys are harsh. I'd be pissed too if I took what I considered a "minor fall" from a bike, bumped my head and got knocked out cold while wearing a helmet. That helmet better have crumpled like no other or else I'd be sending hate mail to the manufacturer.

What did your helmet look like after the fall? Can you post a picture? If it was crushed then I would believe that the foam in the helmet may have helped to slow the impact of your head and brain. However, almost every single broken helmet I have ever seen are split into two halves with a big crack and virtually no crush. What if you you got in a minor fender bender with your car and the crumple zone was split into two? Would that give you any protection? No.

Helmet manufacturers know that there is no way to actually cushion your brain from any real sort of accident without the helmet being so big, heavy, and hot that no consumer would buy one. So they make cool looking ones with a trillion "vents" that dont protect your head and make a fortune doing it.

Helmets are a good idea for small children learning to ride a bike who may fall off and bump their head while riding. I am an adult and that type of accident just does not happen. I want protection from real world accidents but that helmet just does not exist.

With all that in mind I do occasionally wear a helmet on long rides. Its a rock climbing helmet thats not made out of a slurpy cup.

Really? So that time I flatted at speed on a decent ant my bike went out from under me didn't happen?

Or are you talking about low speed accidents, like all of the "clipless falls" we hear about so much here. Are those the accidents that just don't happen?

And let's not forget, helmets can protect against more than just the stereotypic busted skull type of injury. Consider the case of just cutting your head and needing stitches, something that seems likely in even a moderate spill with a head-strike. Even with my health insurance, that's going to cost me $25 just for my co-pay; other services may be more (and I might even see another co-pay when I go to get the stitches removed). Now I just bought a helmet for $34, so I'm at worst paying $9 for the privilege of not having to deal with the pain and hassle of stitches in a case like that.

Price of helmet might not be a reflection on its protective abilities. Didnt the CPSC do a study a couple of years ago that the Bell Citi was theoretically one of the best helmets?

You dont have season helmets? I wear a skateboard style helmet approved for biking in the winter and a "normal" giro helmet in the summer. The winter helmet appears far sturdier and cost far less.

I choose to wear a helmet. No one is forcing me. If it helps, fine. If not, oh well. But I will force others to wear one because I am so concerned about their well being .

Geez, I don't think anyone on this thread has really been a so-called helmet nannie.

For those who choose not to wear helmets, great. Ride, enjoy. For those who wish to wear helmets, great. Ride, enjoy.

In my initial post, I was merely trying to point out that when someone has a "slight" fall, you don't generally end up unconscious with a concussion; helmet or no helmet. I would argue that the fall was either not slight, or the concussion was the result of a force that no functional helmet on earth would have prevented.

I was also stating that in the two occurrences where helmets came into play for me personally, I can honestly say that I would have been much worse off if I hadn't been wearing one.

Incident one: commuting home from work, head meets van as van took a blind left directly in front of me. Helmet had ugly green gash across the front top, and the foam core was split. The green gash would have been on my forehead if not for the helmet. The splitting of the helmet indicates that significant force was absorbed by the splitting of the foam core; it's how they're designed. For the record, it was a $39.95 helmet, not a $300 tour model.

Incident two: nearing the end of a race. Either the chap next to me lost control of his bike, or he thought he was Robbie McEwen and was going to "muscle" his way past me in the sprint. Problem was, the race had already been won (by someone else), we were at best going to get something like 12th place. I let my guard down, he mashed into me from the side. My bike went right out from underneath me. Broke my left femoral neck, had a big road rash on my left shoulder, elbow and hip, and the plastic that covers the foam on my helmet was ground off down deep into the foam, and the foam again was split. This was about a $170 helmet. If not for the helmet, it would have been my head that was missing a few layers of scalp and skull. My face is ugly enough without having a bunch of scar tissue to make matters (arguably) worse.

Personally, I don't care what others opinions may be, or whether this appears to be anecdotal evidence that helmets work. I believe that in these two instances it was better to have been wearing a helmet than not.

So again, if you don't want to wear a helmet.... don't. Free will is an amazing thing.
But if anyone says that they aren't worth it, I'm not convinced.

While this review is clearly either misstated or the helmet was defective, lets think a little more analytically about how helmets work.

First, when your head hits something, with or without a helmet, 100% of the energy is going to be transmitted to your head, unless there is some sort of damage to the helmet. The benefit that the helmet gives you is that is dissipates all that energy over a much longer time than would have happened without the helmet. Also, a helmet breaking in half, cracking, or crumpling all have the effect of transferring some of the impact energy to deforming the helmet, much as crumple zones in cars do. A helmet also spreads the area of impact and lowering the pressure on your head.

My point is that here are all sorts of complicated interactions going on during impacts, and helmets make it even more complicated. Assuming that the helmet was defective because it broke or crumpled isn't very rigorous, and head injuries are so complicated that saying a "minor crash" should or shouldn't have given you a concussion is too hard to analyze as well.

From a study on bicycle helmets. A helmet that has cracked is a helmet that did not do its job. A standard helmets foam is harder than a standard humans skull.


Helmet liners may be too stiff to be effective. Standards require the use of headforms heavier and more rigid than the human head; these are more capable of crushing foam than is the human head. [15][16] In real accidents "very little crushing of the liner foam was usually evident... What in fact happens in a real crash impact is that the human head deforms elastically on impact. The standard impact attenuation test making use of a solid headform does not consider the effect of human head deformation with the result that all acceleration attenuation occurs in compression of the liner. Since the solid headform is more capable of crushing helmet padding, manufacturers have had to provide relatively stiff foam in the helmet so that it would pass the impact attenuation test... As the results in Figure 15 illustrate, the child skull is far from being solid and will deform readily on impact. This fact is well known in the medical field and is largely why a child who has had a rather modest impact to the head is usually admitted to hospital for observation. The substantial elastic deformation of the child head that can occur during impact can result in quite extensive diffuse brain damage."[17]

In real accidents, while broken helmets are common, it is extremely unusual to see any helmet that has compressed foam and thus may have performed as intended. ďAnother source of field experience is our experience with damaged helmets returned to customer service... I collected damaged infant/toddler helmets for several months in 1995. Not only did I not see bottomed out helmets, I didnít see any helmet showing signs of crushing on the inside.Ē [15]

Most helmets provide no protection against rotational injury and may make it worse. "The major discovery is that the skull plays an important role in protecting against rotational acceleration," says Phillips. He says almost all head injuries involve not just a direct blow to the skull but also damage to blood vessels caused by the brain rotating within the skull.

In mechanical terms, the head is an elliptical spheroid with a single universal joint, the neck. It is therefore almost impossible to hit it without causing it to rotate. The head tries to dampen these forces using a combination of built-in defences: the scalp, the hard skull and the cerebrospinal fluid beneath it. During an impact, the scalp acts as rotational shock absorber by both compressing and sliding over the skull. This absorbs energy from the impact." [18]
