if helmets became compulsory...

[ufkacbln]

if they are professionals which i presume they are it wouldnt be wise to ignore their advice. it would however be wise to consider it along with other advice to form a judgement

Yet you clearly state that you do not need any other evidence other than your own opinions!

What other "advice" are you referring to.

witnessed a mate of mine come off his bike, without a doubt the fact he was wearing a helmet saved him from serious injury. im not joking when i say it was literally in a hundred different pieces after his accident and made me think again and i always wear mine now.
each to there own as far as im concerned though, dont think it should be compulsory but i personally would advise all to wear one.

There's a few descents on the Waskerley Way where you need all the protection that you can get.

So the helmet seriously failed by brittle fracture and your friend was seriously injured and yet you are certain it saved his life? Curious.

Of course if it actually offers little protection but you are riding things you wouldn't without the protection you are assuming its an excellent demonstration of risk compensation in action.

A serious question must be how old this helmet was and whether it had ever been dropped, knocked or battered.

It is possible that these fractures were due to weaknesses and subtle fractures caused by previous damage.

Was the helmet actually fit for purpose?

Please don't put words into my mouth.

OK, would you do those descents without any protection? If so you don't need all the protection you can get. If you do need all the protection you can get, presumably you are riding something you would not ride without the protection and if that protection turns out not to be we end up with what I said.

Please don't be presumptuous.
I have no intention of justifying my post to you, so move on.

I'd Probs wear one TBH

BUT only because of my obsession with cycling, 12 months ago, the same question would have resulted in a answer of

Maybe stop, maybe protest

What's the point of posting to a forum if you are not prepared to debate what you have said or defend/retract the accusations you have made?

That's a good point. Polystyrene is not renowned for its brittleness. It will compress, deform or snap under tension but it should never be brittle.

EPS is brittle by definition as it typically breaks with little or no ductile flow or deformation unlike say cling film. So when you snap polystyrene foam its a brittle fracture i.e. it breaks with no plastic deformation taking place first at the break. This is important as brittle fracture absorbs very little energy compared to deformation which is how the helmet is designed to work and absorb energy.
