Default Can't Use Helmets in the Sun????

The "shelf life" of a helmet is VERY long. While sun and UV lights do
degrade a helmet, this degradation is very slow and only effects the
surface layers. Over time the foam does change it's characteristics but
that changes appear to be a wash as far as protection ability of the
helmet.

That being said a helmet offers almost no protection. Do NOT be fooled
into thinking that a helmet will protect your head in all but the very
slightest of accidents.

While 90% of all accidents fall into that catagory you should probably
be aware that just falling over and hitting your head against a curb
will substantially exceed the protective capacity of a helmet.

Wear a helmet if you prefer but don't let it take the place of
intelligent riding. Don't run stop signs. Always ride on the correct
side of the road. Remember that riding with others is perhaps the most
dangerous part of a ride since touching wheels will take you down
faster than anything else.

Default Can't Use Helmets in the Sun????

From http://www.newsreaders.com/guide/netiquette.html:

/Don't excessively cross-post/

* Cross-posting refers to posting a message to more than one group
at a time, in the same post.
* If a message truly belongs in multiple groups, by all means
cross-post. In fact it is better to cross-post than to post the same
message separately to different groups.
* Be careful when replying to a post. The initial post may have
been inappropriately cross-posted; if you do not edit the list of
newsgroups, your reply will also be inappropriately cross-posted.
* Consider setting "followups" to one group. Your post may be
relevant to 3 groups, but you can set followups to one group and then
the discussion will continue there. When using the followup header, it
is nice to put in the message somewhere "Followups set."

And from http://www.use-net.ch/netiquette_engl.html:

/Avoid posting to multiple newsgroups/
Few things annoy Usenet readers as much as multiple copies of a posting
appearing in multiple newsgroups.

NYCXYZ, please stop cross-posting or at least set the Followup-to for
one group. Thanks.

The followups to this message are set to rec.bicycles.misc, a group that
I rarely visit but seems most appropriate for this discussion.

That's the thing -- the exact wording is "direct or indirect heat" --
which I take to mean sunlight as well, and UV exposure in particular.

Just seems an astounding fine-print, if I'm reading this correctly! I
mean, we're talking about the most critical piece of safety equipment
for an activity that generally takes place at daytime in summer....


Uh, no...."the most critical piece of safety equipment" sits behind
your eyes and between your ears. Always take it with you, wherever you
go, whatever you do.

Thing is, I actually like this helmet. It's so comfortable I not only
wouldn't mind wearing it if I had to, but I almost want to wear it just
for the heck of it! Maybe in winter-time I will, for a bit of head
warmth (which I really don't need, but it's a $100 helmet, after
all...). =D

Anyway, I'm reading the manual -- am I the only guy who likes reading
manuals with his cereal?? -- and I notice in Giro's one-size-fits-all
Owner's Manual that they explictly state *twice* that direct or
indirect heat might damage the helmet.

Could that mean that the summer sun's going to damage the helmet????

Are we supposed to replace our helmets every year or two, even if they
aren't banged up, simply due to, I dunno, UV-induced deterioration of
the styrofoam's molecular structure??? (Materials Science is such an
interesting field...they're building the world's biggest Neutron
Smasher or whatever-it's-called down in TN or somewhere...they hope to
come up with all kinds of exotic materials due to understanding and
then manipulating subatomic physics!)

I still hope no one forces me to wear a helemt...but this Giro Roc Loc
4 is so comfy I would hardly mind wearing one now. Just funny to think
that it might not do any good anyway due to prolonged exposure to
direct sunlight!


Well UV rays damage lots of things, the most important being your skin plus
rubber, plastics and painted surfaces, just to name a few. So it sounds
logical that the foam in your $100 plus helmet might be damaged by those
blasted UV rays also.

Ken


The UV rays will not reach the foam inside your helmet.....

You're supposed to read the cereal box.

The helmet manufacturers would love you to think that. For me, it's so
hard to get one that fits that I wear it until the straps decompose.
Which, last time, was only a couple years.

No. What it means is that it may, in fact, "melt" if left in your car with
the windows rolled up. This does happen; car interiors can get incredibly
hot under certain conditions. Worse things happen than melted helmets inside
cars. Giro, and probably most other helmet manufacturers, get a lot of
claims (warranty demands) for helmets that were subject to such heat. The
materials used in a helmet are chosen for suitability in the environment
they're normally used.

But it absolutely, positively will not be rendered useless by riding in
normal conditions. If you were doing a tour on Mercury or Venus? Yeah, it
would probably melt. Don't do that.

As for warnings that the helmet is useless for any and all purposes, those
are standard disclaimers found on many safety products, meant to deflect
lawyers who would argue the absurd notion that the helmet should have been
able to protect in virtually any foreseeable circumstance; thus, helmets are
marketed as much as a fashion item as they are anything having to do with
protecting your skull. Don't blame the helmet companies for that one; in
general, the easiest way to be a target is to manufacture something,
anything, and claim it will make you safer.

Shouldn't that be =) now? No, wait, it's a Giro, make it {=)

Oh, wait, it will prevent the *cause* of STDs. Unless she's...no,
let's not go there.

Damn, that's more than I've paid for every bike helmet I've ever had,
altogether.

Giro is reportedly owned by Bell. Such exactness is therefore
expected. Or else, obviously, the only safe way to store or use the
helmet is in the absence of heat, i.e. at 0 K, which would necessitate
that the wearer would need to be similarly cool-headed. Perhaps this
could afford us the opportunity to investigate Niven's postulate that
the brain might become a superconductor at that temp. Inquiring minds
want to know!

Could that mean that the summer sun's going to damage the helmet????


If you're in the habit or parking under magnifying glasses, quite
possibly.

I -do not- want to know what you were doing when you wrote that. In
fact, I am reasonably certain that I actively want to -not know- what
you were doing, and have a strong interest in failing to investigate
whether that is an accurate perception.

Just funny to think
that it might not do any good anyway due to prolonged exposure to
direct sunlight!


Oh, the opportunities.

/mode (regrettably, I am unable to find an example of a "rolling
the eyes and shaking the head" smiley.)

Remember: The important part of the helmet is the part on your head,
not the box or the propaganda.

They don't sell helmets among other cycling accessories on there?
(Newsgroup restored so no one missed this vital discussion.) And why did
you trim the OTHER groups?
