I had heard that Trek was going to have a new material for their bike
frames. Well, in fact it is a new material for helmets. Styrofoam
worked for preventing skull fractures but that is not a source of
cycling injuries on the whole - concussions are.

The new material will NOT offer the ultimate safety as the Styrofoam
did but it is WAY softer in the manner of crushing and will eliminate
most of the concussions. While this won't meet the helmet standards I
have no doubt that they will make a new standard for this material
since it will probably save 70% or more of the NORMAL injuries from
bicycle accidents.


Looking at statistics from the EU, it seems that about 80% of cycling
injuries presented at the ER, are to body regions other than the head.


How can a new helmet material save 70% of the normal injuries from
bicycle accidents when 80% of the injured don't have a head injury?

There's an article about the new helmet material he
https://www.popsci.com/trek-wavecel-bicycle-helmet-science#page-5. The
key feature is the improved concussion protection.

And as usual, the unspoken assumption behind the article
is that cycling produces so many brain injuries that
cyclists _need_ protection.

Yet any dispassionate examination of the relevant data
shows that cycling is not abnormally risky. Cyclists
comprise only a tiny percentage of serious brain injury
victims, and cycling's benefits far outweigh its tiny
risks.

But that doesn't even slow down the fear mongers.

But Frank. It's NEW and they say that it is better and everyone knows
that a helmet will save your life. What's not to like?

And $149.99 (plus shipping) for the cheap one and $299.99 for the
better (one assumes) model :-)
