were you not wearing a helmet. *

Tom is not stupid, and is not a fool on a crusade against helmets.
There's no need to go making sarcastic attacks on his statement. All he
is doing is being realistic. The damage to a helmet is not equal or
directly comparable to that of an unguarded head in the same crash. As
far as I can tell, that is all he is saying.

And technically, assuming you didn't have a windshield, being without a
seatbelt can be better, since you could end up flying into a pool of
water or sand rather than having a hard piece of cloth crush your
collarbone (you run into a low brick wall at the edge of a harbor, for
example).

I've been on cycling newsgroups too long to be interested in getting
into helmet wars. All I am saying is that it is an obvious physical
fact that you're more likely to hit your helmet than you are to hit your
unprotected head, therefore the fact that someone hit his helmet in a
crash doesn't mean that he would have hit his head.

I don't believe that Tom is stupid. Show the picture of the helmet to a
bunch of people and some will believe that it saved the riders life or
spared him from head injuries. Others will say that it is inconclusive
because the helmet is much larger than ones head and will cause more
damage to the riders neck because it extends outward and will cause neck
trauma.

Some of these same people also believe that seat belts are dangerous
because of the small chance that you would get hurt in a side impact
crash or you would be trapped if you landed in the water. It doesn't
matter that wearing a seat belt saves many more lives than they take.

even if he wouldn't have hit is head it saved his neck from whiplash.
There were three options, helmet - no damage, no helmet - neck absorbs
shock but saves head (still hurts), no helmet - head expodes. The two
no helmet options don't sound like fun to me.

The issue isn't the size and mass of the human body, it's the size and
mass of the human head. A helmet adds about 10% to the weight of your
head, and raises the center of gravity relative to the pivot point (your
neck), while increasing the diameter by 5-10cm. Any engineer who tells
you those facts don't increase the chance of an impact in a fall is
trying to sell you something.

Note that I'm not saying such impacts are inherently a bad thing; they
will almost certainly be in the range of impacts a helmet can actually
protect against. I am, once again, merely pointing out that a helmet
impact would not necessarily have been a head impact.

even if it wouldn't 'necessarily' have been a head impact, i bet evan is
glad that he didn't take the chance!!!

being able to show off helmet damage is much cooler than being able to
show off head damage 🙂

haha yeah if you were lucky like that maybe you would fair off better.

Helmit is so better then not though I do bet that your more likely to
take a hit/slightly harder hit with one on. There's still that wiplash
efect though that you cant really stop when you fall sometimes. It just
doesnt matter what youre wairing you take a hit. The Mythbusters should
do a segmint on this.

Let's face it. There are just too few candidates for the Darwin awards
lately.

So if anyone doesn't want to wear a helmet, I say fine. Let 'em wear a
ziplock baggy full of pudding if they want. Or not.

In either case, it will be all in good clean fun when we pass the
entertaining story of their death around via email next year.

Thanks in advance for the laugh.

BTW, can I have some of your stuff? Your Uni? Or maybe the unused
helmet? Any unopened pudding at least?

So of course you're now going to start wearing a full-face helmet, since
it's his face shield that's cracked.

well the reason i noticed it 5 days after is right after the crash i
just stood up and dusted my self off, checked to make sure everything
was ok, then i got back on, rode home, and when i take my helmet off i
dont like put it in a cabnient or soemthing so i just kinda chucked it
onto the ground and didnt look at the back.

What you wrote is: "Let's be realistic ... [hitting your helmet] is
not at all proof that you would have hit your head."

That's pretty strong wording in my book, so I assume you have an
anti-helmet prejudice. Admittedly that's an assumption on my part.
If I am wrong, just say so. Either way, it is fair to assume that I'm
not the only one who read it that way, so pro-helmet responses seem
right on target to me.

And yes, I have a pro-helmet bias. The issue came up in R.S.U a while
ago. I searched for credible evidence that helmets actually do
measurable harm in low energy impacts and, despite lots of noise from
anti-helmet folks, could not find any support for the notion. I did
find a paper by bicycle dsafety experts from a university in the UK
systematically refuting the claims.

Lastly, getting back to being "realistic". I've hit my helmet many
times and have yet to create a tear in the shell that large. Based
just on the damage to the helmet, I have to conclude that Evan was
fortunate to have been wearing it.

I already wear one when doing DH mountain biking, you'd be stupid not
