Helmets - mean time betweef failures

Recommendations for one with significantly longer life span? I had just got fond of it too, sort of like an old sweater with holes in it that you don't want to give up. I bought my Bell in 1986, wore it every day for ten years, less regularly since then. I see no need to replace it. Theo |

Let's just say that I'm a hell of a lot more competent as a commuter than I am an off road cyclist. Three bimbles in the space of an hour, one of which saw me (much to my surprise and delight) digging deep in to my long dormant judo roll skills ;-) -- EuanB |

Helmets - mean time betweef failures
Ah, well you have a choice in everything, just like we aren't supposed
to talk on mobiles while driving - but many do. Travelling down brunswick st how many people do you see with the helmet on the handlebars. Again your choice It's not that I think we should all wear our helmets and need to swap them over regardless every two years. But in answer to the original poster, the lifetime of a helmet is quite defined and lessened by exposure to UV, and body oils and hair products. I was trying to point out that the is quite likely no way to guarantee the working life of a helmet and in fact the actual use will accelerate the wear. An old sweater may be comfy, but a five year old helmet most likely will not provide the full impact absorbtion of a new helmet, that's my point |

When I ring to try to get my helmet repaired, I get the "replace every 3 years" line. This sounds like the bike shop trying to sell more helmets to me. I'd be interested to see the evidence on the deterioration models. Still, I'll be buying a new one soon enough... Dee Bub -- Dee Dub |

If your Betamax recorder still works then who am I to argue.
