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

Get a clue, NYC...many outdoor products have a "shelf life" (e.g., tents, lawn furniture, etc.), due to the effects of UV and heat. In the case of helmets, there's also the fact that they are designed to be light and comfortable. You could probably design a stainless steel helmet that was not subject to UV breakdown...but, you wouldn't want to wear it. Gary, it takes *a lot* of UV exposure to break down plastics. We've all seen styrofoam cups, coolers, and beach toys crumbling from exposure to the elements, but we forget they've been lying around outside for decades, and exposed to worse things than UV. Helmets may get a few hours a day of exposure, a few times a week, if that. Newer ones have non-structural plastic caps on them, and dyes in the styrofoam to protect from UV. So the structural styrofoam is well protected. Basically this is not worth worrying about. Matt O. |

What scares me most here is the near certainty that I'm the only one
who's reminded of that old Terry Jacks song; We had joy We had fun We had helmets in the sun... Man ... was that song a bag of downers or what? |

More wife, less usenet. Problem solved. Two cents, please. Paul Hobson wrote: Honestly, NYC XYZ annoys the crap out of me. It boggles my mind that people reply to this "former NYC messenger's" asinine questions. That said, I'm confident that these posts belong neither in rec.bikes.tech or rec.bikes.marketplace. Maybe they do. Who knows? \\paul |

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 Um, I doubt they'd get away with a disclaimer which disavows the intended use of the product! |

Wearing the helmet on your ass voids the warranty. Martin Borsje wrote: The UV rays will not reach the foam inside your helmet..... -- Posted by news://news.nb.nu |

Right -- I was only wondering, though, how they could sound as if they're admitting that their helmets are useless! I mean, I was always suspicious of mere styrofoam, but if even they themselves will say that mere sunlight and heat can damage it -- and thus negate the whole point of wearing one...well, I dunno, maybe helmets are for dummies who can't see the contradiction in that! Energy-absorbing car bumpers are made from EPS foam, like helmets. Automakers don't seem terribly concerned about the implications of exposing a car bumper to environmental levels of heat. Of course, they know if they tell you "replace your bumper if it gets hot", then that will make you less inclined to buy their particular product again, whereas the functional monopoly on bike helmets makes any helmet replacement an overwhelmingly likely sale for Bell Sports (who make both Bell and Giro helmets).

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. Yeah, OK. So, what is your point. I would rather fall over and hit my hit while wearing a helmet than while not wearing a helmet. Sid |
