The serious injuries not caused by concussion are in general VERY serious - being hit by a car is foremost. There is no safety equipment of any kind that can prevent these. Also those that we can classify "injuries" are almost never very serious and we certainly are not going to go about wearing carbon fiber armor to prevent minor injuries. The serious injuries that are single or multiple bicycle injuries are foremost head injuries causing concussion which can range from causing death to giving you a headache with the vast majority in between. So, yes, most bicycle deaths and serious injuries are caused by auto accidents but there is no cure for that. But the injuries that can be mollified are all those a helmet could perhaps reduce and the old style helmets cannot do that. So perhaps as much as 70-80% of these injuries could be either greatly reduced in severity or eliminated with this newly designed material. Also this stuff weighs almost nothing - a small fraction of what your Styrofoam bucket does. That alone can convince some people to use it. Now, like all new products, we can't tell the real efficacy of it and it will PROBABLY take years to gather enough data to make a sound judgement. But there is a small possibility that this could be so effective that it turns up almost immediately. Let's hope the later. |

How can a new helmet material save 70% of the normal injuries from bicycle accidents when 80% of the injured don't have a head injury? There's an article about the new helmet material he https://www.popsci.com/trek-wavecel-bicycle-helmet-science#page-5. The key feature is the improved concussion protection. And as usual, the unspoken assumption behind the article is that cycling produces so many brain injuries that cyclists _need_ protection. Yet any dispassionate examination of the relevant data shows that cycling is not abnormally risky. Cyclists comprise only a tiny percentage of serious brain injury victims, and cycling's benefits far outweigh its tiny risks. But that doesn't even slow down the fear mongers. - Frank Krygowski Frank, you obviously rarely fall or ride with people that do. In fact concussions are VERY common. They can just be like someone falling down and being disoriented to the point that he cannot stand properly or remember where he was going to ride to. Or like my case in which I was out of it for 2 years and having seizures until a proper neurologist treated them. I had a couple before the one that fixed me up and they didn't have a clue what they were doing. Since most neurologists end up with a large percentage of their patients suffering from aging diseases the workings of concussion go out of their mind. I have spoken to several neurologists since then who also don't even have a clue how to treat concussion. One even had the opinion that there was no such thing. I have fallen four times in the last five years and two of those I was slightly concussed, so it isn't something to take lightly. And even though I agree with you that the present helmets are little better than nothing, we do know that it is possible to do better. |

"this stuff weighs almost nothing " From the guy who considered the difference between a Campagnolo chain and a Wippermann chain to be significant. Or a titanium seat post clamp bolt for only $9.00 and the nut (required) for only $4.50. think of it, the lightest seat bolt clamp bolt in town.... right there on your very own bicycle :-) -- Cheers, John B. |

The study done by the California Highway Patrol in Los Angeles County showed that of the accidents, where it was possible to assign fault, some 60% were essentially the fault of the cyclist. It might be noted that a substantial number of the accidents involved the cyclist riding the wrong way on a one way road which seems a rather minor fault... except that it resulted in a collision between a bicycle and an automobile. -- Cheers, John B. |

Sort of like your Mama told you to always walk facing traffic, I guess. -- Cheers, John B. |

Just out of curiosity - do you wear a helmet? A lot of people, including me that do find the weight of them tiring on the neck. So if you think that a lighter material is good because it makes your overall weight less perhaps you ought to rethink something. That is on the off-hand guess that you can think at all. But then I don't often see postings on this group that require any more thought than you could get from a 12 year old. Let Frank tell us all again that I didn't watch my speedo go up after I went onto a smooth surface when it took hardly a minute before the Physics forum determined why that was. And I have verified their determination since by accelerating hard from a stop light and then watch the speed increase after I started coasting. Perhaps you've nothing better than to play with yourself because you're worn out.. |

Active sports cyclists ride always with the fear of a collision whereas every time I ride through the cities I see the most bizarre behaviors. The other day, on a busy street, there was a kid riding down the wrong side of the road with no hands and texting on his phone. Even homeless people rarely commit such stupid acts and then I suppose because they're high. |
