Not very surprising. The government standards are just "Minimum" standards.. Not maximum. Kind of like plumbing and natural gas pipes in houses. They have a minimum PSI rating that indicates how much pressure they can stand before bursting. They have to meet a minimum standard. Double the wall thickness and they will be much stronger than the minimum. Better? I suppose. But at what cost? Safest way to bicycle is to use one of those exercise bikes in the basement inside your bomb shelter. Not much danger of hitting your head, assuming you don't trip getting off the bike. But you could put 2" foam on the floors to protect from falling. And you're protected from nuclear bombs by your bomb shelter.

I buy mine from Bell. They are quite thorough when it comes to impact
testing.

Bell invented the tested safety helmet. They do a good job for what that is worth - not much. A helmet will help prevent contusions and abrasions in minor falls but they are designed to sustain forces that will break the meniscus holding the brain inside the skull allowing the brain to smash into the skull which is then protected from breaking by the design of the helmet. So rather than the skull giving and reducing brain injuries the helmet can actually increase them.

Actually Mother Nature did a pretty good job of protecting the brain. The skull will crack reducing accelerative forces and preventing brain damage in a better means than a helmet will. Not that I'm suggesting you try that since there is an extremely narrow band of injuries that the helmet was designed to prevent

Bell has invented their new Zephyr and Giro, part of the same company, makes one as well. They are using a newer technology. There are two shells instead of one. The inside shell has less resistance and hence will reduce the initial decelerative forces and reduce the chances of brain damage from concussion. The outside layer has slightly more resistance but at this time one could theorize that the brain has hopefully decelerated enough that concussion is less likely from the higher decelerative forces of the outside layer. These two layers together will pass the safety tests from the various agencies.

They also have re-designed the plastic cage that fits around the head so that if you hit at an angle it allows the helmet to turn on the head unlike all of the old designs which would hold the head rigidly in place possibly hurting the neck. They have also added the function of redirecting sweat away from your brow where it would drip onto your sunglasses.

The only trouble I can see is the cost - $240 for the Bell and $380 for the Giro. Well beyond my present means.

DO NOT believe any of these stupid testing methods. Specialists in traumatic brain injuries are NOT consulted when these testing procedures are written and they are all totally blind to the actual injuries of concussion and its ensuing problems of convulsions caused by the concussion. Also as far as I can make out rather than engineers they are designed by physicists. If there is anything dumber than a physicist applying anything to the human body I can't think of one. (The stories I could tell you about designing things for the military)

I was just lucky to find a neurologist that both knew how to treat traumatic brain injury and to make the treatment cheap enough that I could afford it.

I was just lucky to find a neurologist that both knew how to treat traumatic brain injury and to make the treatment cheap enough that I could afford it.

And let me repeat - in any case the range of injuries that they were originally designed to prevent was extremely narrow - the fall of a weight equal to that of THE HEAD ALONE of 6' and at a decelerative force that would prevent skull fracture in most cases. MOST - they do not work at all for children and yet children's helmets have the same testing procedures.

What does this mean? That THE ONLY injury that a helmet is designed to prevent is skull fracture over an extremely limited range. A lesser impact or one with body weight behind it changes the parameters and in every case will not prevent injuries of the sort it was designed to prevent.

Helmet ARE NOT DESIGNED to prevent or even ameliorate concussions.

Not ONE of the studies I've read makes the slightest sense nor do they in any manner show that helmets prevent anything other than very minor injuries.

One REALLY stupid study proving helmets work - 84% of bicyclists presented at ER's with traumatic brain injuries were not wearing helmets. Well virtually every competent cyclist wears a helmet as part of the kit. So that number is absolutely meaningless. Not to mention that 79% of those presenting had drugs or alcohol in their systems. All that proved was that drunken homeless people are careless.

Something like 90% of all emergency room doctors recommend helmets. ER doctors for the most part are interns - first year doctors fresh out of school and with little to no judgement in matters of engineering.

I could go on.

My published study showed plainly that helmets do not work. My recent study with the information since 2000 showed no changes. If there is a narrow band in which the worst possibilities are prevented there is insufficient data to show it.

And on this very site, after I referenced that study you simply cannot believe the effect it had. I had people completely outraged that I could say helmets don't save lives. Several of the people that are still posting here started strings like "Tom Kunich is an ASSHOLE" or worse. (When I'm looking for a job most HR people will do a search on my name and spot that. I've often been asked about it. But the same companies that later sent me and my wife to New York or Chez Panisse to try to coax me to stay with their company.)

I happened to have paid off my mother's house since I was a well paid engineer at the time. She had divorced my father and remarried and re-divorced so she didn't have my name any more.

But of ALL people, Jobst Brant published the address of my mother's house complete with a map of how to get to it. Though someone else said it belonged to some totally unrelated Mary Kunich (which is a common Croatian name - there is even another unrelated Tom Kunich in the same town since I inherited the house when my mother died.) One of the fine upstanding people on the group beside throwing trash all over the front yard and chalking "Tom Kunich is an ASSHOLE on the driveway even took a crap on the front porch. Luckily this was after my mother died and I had rented the place out since I was married and living three cities away.

These are the sorts of inhabitants of this group and you would do well to understand that anonymous names are assumed by people that do not mean well or do not mean to be identified by those same people.


Welcome back, Tom.

Somebody just sent me a "Tom Kunich is an ASSHOLE" reference so I thought I'd stop in. I didn't need that job anyway.
