Problem of cyclehelmet.org is that it’s a website and like any web site anyone can put anything on it.
TJ’s arguement will probably have much more value if he could back them up with some proper peer-reviewed paper. But again you can always raise them with another:
Make helmet compulsory ======> Australian study saying less people ride======> Another journal saying that people without helmet are more likely to commit traffic offenses etc etc. As for the health benefit do people who stop cycling drive their cars or walk and take the bus that woudl made a huge impact on the health as well. PLus for such study to be valid you would need to have a ref sample of people.
As said above look at helmet such as the Xen more coverage, provides very good fit plus it’s rounder.
Like MrA says you can’t really compare motorbike helmets and bike helmets are you against motorbike helmet made compulsory then?
One of the problem is that in motorbike world it’s an accepted fact that you need to protect your skin. Hence even TJ I am sure wears helmet and gloves and boots etc etc…
It as not come down to cycling yet. But things are changing. A bit like the hi viz jacket not smart not legal but life saving.
As for the rotational injuries I remember reading that TJ’s motorbike helmet were all the wrong size because the bigger the better. As for rotational injuries there is nothign to protect you from that even in the motorbike world.
However laser are developing a soft skin/membrane to try to asses the problem.
As yo said each to their own TJ so you are anti helmet I am pro helmet I am sure even edimbourgh without tourist is big enough for the both of us.
