In a previous post, we looked at how bicycle helmets protect the head. Now lets look at how they're produced. Surely any helmet design will look good on paper but effectively manufacturing it under cost and time constraints is entirely another thing. But I must admit I have something against the way that shell and foam are attached, as in taped (watch the video)! Of course, there are other ways to piece them together. Bell uses what they term 'co-molding'. That drop test also seems insufficient, keeping in mind the many scenarios in which a cyclist can crash. Video courtesy of user RameshKumar123.
Now one wonders how popular cycling helmets out there are so expensive. Does R&D and testing take up the costs or are there more factors involved? And what is so state-of-the-art about the latest research on bicycling helmets? Isn't the same knowledge used pretty much year after year or is it otherwise? Marketing trendiness of "pro-helmets" with a thousand vents must also be near the top of the list for the hefty price tags. Feel free to drop a comment.
