Remember kids... always wear a helmet. (The almighty bikeradar helmet thread)

We do things every day that we believe good for us without having information on the subject. I don't think you'd argue that eating fruit and veg isn't a good idea but have you ever read a peer-reviewed study on it? We can't be arsed to research everything we do, so on some level we have to trust others to do it for us.

Actually I am not at all convinced on the subject of fruit and veg (and I am a vegetarian) but that is for another thread.

Now I'm sure that a lot of it is bullshit invented by marketing departments to increase sales but I personally don't think that it is all founded on crap. The Tour mandates the wearing of helmets; those people aren't idiots (well, not all of them). There are standards for helmet construction, these came from somewhere, and presumably at some point they'd have noticed if the performance of them was indistinguishable from not wearing one. If you really believe that this occurred and that there is some great conspiracy on the part of Skid-lid™ to cover it up then so be it, but I just don't think the PR department at a bike helmet company is really comprised of people who are that smart.

Extrapolating from what professional racing cyclists do is always dodgy. The UCI obliges them to wear helmets; before that most chose not to do so. That is a fact. What choices they would make now is speculation.
How can it possibly be in the commercial interests of a helmet manufacturer to point out the severe limitations on the efficacy of their product or direct anyone to the research which suggests helmet wearing is not, overall, beneficial? Of course they are not going to and ofcourse the staff in Evans aren't going to. That is not a conspiracy and I did not use the word conspiracy. I am saying there are commercial imperatives involved in the increased wearing of cycle helmets and they have nothing at all to do with informed choices or accurate risk assessments.
