Helmets - mean time betweef failures
Met offer a crash replacement policy, not free but cheaper than buying
a new helmet. Some distributors offer an inspection service, but none offer a repair service. Kinda hard to do repairs on one part of a helmet, as the helmet as a whole absorbs the impact and impact damage is not neccessarily visible. Plus I dont think anyone would want to place their name behiond the partial refurbishment of a used helmet |

Peter Keller Wrote: I agree with all your points, that bicycling is very safe, and helmets don't do much to improve safety. However, this thread started with a legitimate question on how long a helmet (or more specifically the polystyrofoam liner) should last. Every query's legitimate in my book, but I take your point. Take my point that earlier in the thread I gave a considered reply, which has been echoed by others. I can't really see the connection between that and whether one should be wearing a helmet at all!! That post was in response to a post stating that anyone who does not wear a helmet may have `a five dollar head.' -- EuanB |

As a law abiding resident (working on citizenship) I don't. Well. maybe...... but I for one am quite happy to wear a helmet, even on 35degree days. The day the you go too far on your new ETSX, or too close to that tree on the corner, you might want that helmet on your noggin. I don't consider mountain biking to be as safe as normal cycling. The terrain is challenging and I'm generally pushing myself really hard, esepcially at the moment as I don't have mountain bike fitness. I wouldn't consider riding off road without a helmet as the risk of coming off is far greater than it is on the road. The ETSX is a lot of fun :-) -- EuanB |

The primary threat to my safety is my own lack of skill. Whereas on the road, the primary threat to my safety is something I can't control - other drivers. If I come off my bike, downhill, at 60km/h, it's going to hurt regardless of whether I'm on the road or the trail. But at least on the trail, I'm not going to concurrently get hit by a tonne of metal. Tam |

I am not sure if an "inspection" service is useful at all. The propaganda is that after any knock, however minor, the helmet should be replaced as damage to it may be invisible but still real, thus lessening greatly whatever protective properties it had.

Peter I found a miniature compression spot on a helmet after I'd stacked it... which happened to correspond to a small bruise on my head, so I decided to check it out. When we peeled back the plastic, we found a massive crack that was not at all visible from outside. The bike shop was very responsible and insisted I smash the crap out of the helmet so that no one would take it out of the bin and try to use it. The thought of that scared me - I am always amazed when people sell second hand bikes with a helmet included. Tam |

The connection is that, if you leave your helmet in a dark cupboard and never get it out, it should last a very long time. Theo |

Rayc wrote: so manufactuers have said 5 yr max and then you need to factor in wear accelerants(sp?) but then again do you want to stretch the ability of a helmet to effectively absorb impact force? Just to make life more difficult... The bod in charge of testing motorcycle helmets for Oz compliance recently tested a bunch of old helmets - some worn a lot, some not much, the oldest 12 years old. They all passed. Meaning that it isn't at all clear that age wearies them and the years contemn. It looks like just crashes bugger 'em up. As to the original problem of polystyrene falling off, I suspect that there isn't enough info about minor knocks and UV exposure to give a good answer. Zebee |

was almost, but not quite, entirely unlike tea: downhill, at 60km/h, it's going to hurt regardless of whether I'm on the road or the trail. But at least on the trail, I'm not going to concurrently get hit by a tonne of metal. Yeahbut, at least a car is theoretically movable[1], and hence absorbs some of your energy. A tree is a rather immovable object [1] Why is it that tiny little 600kg cars always seem to give me more room? Oh yeah, they'd feel it -- TimC It's written GNU/Linux, and pronounced "Linux".
