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. |

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. |

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.

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???? 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. --Mike-- Chain Reaction Bicycles www.ChainReactionBicycles.com "NYC XYZ" wrote in message oups.com...

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. 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.
