I tried to get a discussion going looking at the design of bicycle helmets. The only thing brought up about my post was my decision not to wear one. As a lifelong motorcyclist bicycle helmets remind me of 70's motorcycle helmets. They are better than no helmet at all but bicycle helmets could be better designed and made of better materials such as modern day composites. I read of the testing method using a slegehammer. How many cyclist are going to run into a slegehammer? The technology and the materials are available. With all the cyclist out there now why doesnt a major manufacturer produce a better helmet? I read about a couple of companies in Europe making composite helmets but some company should have one avalable in the US. A plastic helmet will protect your head from a blow but it causes neck injuries when it slides on asphalt. The present day helmet will probably work good for a mountain biker but I think its a poor product for the road cyclist.
