It’s time to switch to the Green Straw Helmet

I never knew until this year. My wife says that I have changed dramatically since cracking my helmet this past July. Sadly, I can feel it myself. Still having flashbacks and returning memories of the accident. Can't shake the idea that it may happen again.
Best.

Isn't there another new standard in the EU out or coming out that is supposed to reduce risk of concussion? Or am I not remembering what I read correctly?
Yes, the Alpinestars guy said that their new Adv helmet exceeds the new standard by 40%.

What the new standard is I am unaware of.

Functionally the new standard makes it important for everyone with a helmet meeting the old standard should get a new standard one.

The Koroyd green tubes taking the risk down to 5% is pretty darn good.

I've twice thrown Schuberth helmets at the ground, with zero head injuries (fortunately). That's anecdotal, of course, but I've been happy with their crash performance, as well as their features and all-day comfort.

The new Schuberth C4 Pro Carbon looks quite tempting at just 1400 grams (3.08 lbs).

Still, the Koroyd technology looks interesting, and might be worth some further research. I'd love to see some independent reviews with more hands-on data, and less polished marketing music videos and shiny logos...

Any idea when the Klim Krios Pro Helmets will be available for purchase and evaluation?

I don't know why they can't just say 'approval' or 'approve(d)' instead of 'homologate' or 'homologation'. Gotta love committees justifying their existence. Not saying that improving the standards is bad, it isn't of course but why not work within the existing standards bodies to have an ECE+ or ECE-R for racing rather than create yet another 'homologating' authority especially when it is for such a limited use case (only grand prix tracks). Creating another sanctioning body to add one more test to an existing process that is already performed by ECE seems like overkill and a money grab. Just sayin'

The visor makes it easy to ride into the sun.
That is something I've struggled with, and wondered how well a visor like this would actually work on the street.

The Krios Pro Helmets do seem to be easily convertible, to cover a wide range of situations. I rarely see street speeds where this would be a problem, but it sounds like you could pop the visor off quickly if needed.

Interesting...

The last Shoei helmet I had before Schuberth was a tank, It was significantly heavier and survived numerous incidents well past the point I should have replaced it but it now sits in a corner as a paperweight.
The weight and the canard style of the chin portion of the helmet caused quite a bit of fatigue due to wind buffeting on the old shoei.

Last i'd heard DOT spec only required 290G, well beyond what the medically backed data suggests was even close to preventing head injuries.

What seems to be missing the most from helmet designs is UV filtering in the lenses. That patch of our face poking out of the helmet receives considerable doses of UV exposure during our rides while the rest of us is usually fully protected.

I use my Adv helmet for dirt and pavement riding and agree it helps with sun issues. Nothing worse than staring into a rising or setting sun for a couple of hours. I do wish the shield makers would improve the UV protection. I go on the road for months at a time and remembering to put on sunscreen every time I stop for fuel is not ingrained in my routine. It leaves me with a very well defined hemet tan after the first week on the road. : (

I am looking forward to the new Klim but won't pre-order. I need to try on different sizes in a store to make a helmet purchase when switching brands.

I wonder if their face shield will be available with Transition treatments. I didn't see anything on it on Klim's site. My Klim TK1200 has it, and it's a definite advantage over a standard clear shield. I also wonder what the Carbon Fiber in a Koroyd’s configurated helmet is going to do with devices like the Sena and Cardio products. There's been discussion in the past about the effects that Carbon Fiber has on these devices, only time will tell. Looking forward to reading more on this technology.

While the new standard addresses head injury and would absorb direct impact more than previously, I believe accompanying neck injury is still a huge, and possibly equally fatal, issue. The greater absorption the helmet provides should mitigate more of the transferred force to the neck/spine than previously, but I believe that still remains a very big part of the overall consideration.

I purchased the green straw helmet when the local dealer was having a moving sale and 15% off. I needed a new larger helmet anyway.

Trying the helmet on a couple months before the purchase had me thinking the helmet would be uncomfortable because of the very thin top liner pad. Sort of tugged on my balding hair. Not so when actually riding with the helmet, as I find it to be very comfortable for my head that fit Shoei well and Schuberth with a simple forehead foam modification.

The magnetic chin strap closure if magic. It closes all by itself, seemingly.

The visor works well in the bright sun. Both my glasses and visor are Transitions, and work well together. Washing off the bugs displays little clear dots with the visor dark. For a few seconds.

Airflow is what you might think with ribbons of foam and green straws, very well indeed.

The adventure visor isn't affected by the speeds we rode, but it is quickly removable without tools anyway. Sure works well with low sun levels.
