What is the test about? I doesn't show how much it bends when it hits your head. Carbon fiber is more flexi. But your skull will be broken and you would be dead anyway, just helmet would stay usable ... Nice one :o)
What a bullship test. The brick hit the polycarbonate helmet with a sharp corner full on while the fiberglass helmet was only hit with a glancing blow with the brick sliding off the side of the helmet. The damage also shows this difference.
IIRC their suits have been fitted with a sort of back support for a while which protects the spine and *partially* protects the neck. Statistical studies have also shown that full head helmets reduce the risk of neck injury by 15% (not a lot but any percent is good percent I guess 🤷♂️)
First of all.. Technically polycarbonate is supposed to be 4 times stronger than fiberglass when comes to impact.. Two criteria i am in doubt 1. Is LS2 helmet a true polycarbonate helmet or a fake ebay ls2? Shoei also have fakes.. 2. Assuming both helmets are original.. The years on the helmet (lifespan) plays a part on impact testing. Actual impact testing, original vs orignal, new vs new, impact testing must be in a controlled manner only can really tell the actual results. So to begin with.. I highly doubt both helmet wether is it orignal or fake
4 hours to 100% charge time: maybe when brand new. Before long it takes twice that. I've had my current phone about 6 years but it still recharges really fast. Why can't they put a decent battery in these things?
The beginning of this video sounds like 'snell' is a scammy, detached college student's thesis project Hopefully, they obeyed the laws of physics ...wow
I saw an article a long time ago by a big smercan moto magazine.they said polycarbonate actually absorbs better on inpact,kind of like crumple zones in cars.i still buy fiberglass
Twice it had saved my life and now I own the tech 10 system. I wear it on the street. The first time I got hit by a drunk driver at 60mph. Witness said it was like watching a ball bounce down the street. Saved my life. Second time wasn’t as bad but could have been without the vest. Lightweight, comfortable, and it saves your life. No brainer.
please dont use the tech 10 on the street, use the 5. just because its cheaper doesnt mean it works less well, trust me. the 10 wont deploy in crashes where you are stationary such as rear ends at traffic lights since its built for track use. keep safe!
@@johntucker3992actually there’s two riding modes, street and race. Please research before spreading wrong information as your comment could stop someone from buying this safety device, which could one day save their life.
So you take a no name brand polycarbonate helmet I've never even heard of and put it up against a very high end fiberglass helmet. why don't you redo the experiment using an HJC CS-MX2 Creed with an advanced polycarbonate composite shell and see how that works out.
Sorry to say but this video is not a valid test and it's just destroying the a decent helmet for 54k views.... (Shoei was already broken anyway ;)) If someone's head was inside that Shoei at the moment of impact the skull would be broken and the brain likely partially smashed, after that the shell would return to its original shape. You can't judge by just looking just at the shell. Second, the angle of impact, are you sure they were identical or close to? In my opinion the greatest advantage of composite shells is way better shock absorption so that when one's head hits the ground it's not bounced straight away (just like shock absorbers in vehicle suspension).
Holy crap! Looking at the video frame by frame, the fiberglass helmet collapsed downward about 30% until the face opening was no longer visible. The helmet then flexed back to its original shape...but will your head flex back to its original shape??? Next test put a watermelon or styrofoam head in the helmet. Wow....thanks for the video!
I am very much in doubt that having an blunt object like that hitting you with that weight and speed would be survivable. So, as result the rider would be just as much dead in either of those helmets. And therefore I think this "test" is really not so much doing any real justice. I think that the real question here is this: Does a cheaper polycarbonate provide enough protection to save your day in an accident that is survivable when wearing more expensive a fiber/resin helmet?
How do I know which size is right for me? I have an alpinestars missile v2 professional size 52. I tried the airbag and the size S is really tight and hurts a little in the armpits. Should it be like this or is size M better where there is some slack?
The orientation of the block on impact plays a roll here. Would love to see the same experiment with bowling balls or something. Not the the results would nessisarily be that different, it would just remove one more extraneous variable.
this hardly replicates crash, because both helmets are squashed out of shape when you watch slo-mo, i dunno about you, but my head bones are not elastic, if someting squashed the helmet like that, you'll be dead, even with an 'intact' helmet...(just play the video on 0.25 speed and pause it at 1:45 the helmet is squashed almost to the floor) of course in real crash your head bounces somewhat, so for sure fiberglass is better option, but both of those impacts are pretty scary
The most unscientific test. Idiotic nonsense like this shouldn't be posted on YT. Fiberglass might as well be better but this is nowhere close to be qualified as a comparison.
Just researching the techair 5. Guessing yours was the older version. You had broken your neck in 3 places from the 1st crash....how the heck were you able or even allowed to race 6 weeks later to crash again and did that have a compounded effect on the breaks? Have you tried any of the airbag pants?
Like everything else in this world... Wanna really protect you brain ? Then it's gonna cost you $1700 ... Wanna kinda protect your brain and have the cops leave you alone ? Then $189.99
Fiberglass is sturdier, lighter, disperses impact better. However i dont have many options( i have a weird head and live in a country where you eather by a shoei /arai /shark ) or you buy those sub 200 dollar helmet (barely any supplyers). Im 186 cm but have a size small head. I tryed an arai and my nose touches the chinbar, shark and suomy had too much up and down shake , agv gave me instant all round headacke, pressure on all the wrong points and still shaked up n down too much, unik policarbonate c01 fit the best, and didnt hurt but had plenty of preassure, rather have a well fitting helmet then a loosely fitting one . No im not shopping online the returns would be too much , no online domestic supplyers . Also your skull still has rigidity . Try and find a video of a chinese man with a shtty openface getting his head run over by a truck video( he survived ) but the helmet looked completely deformed. His helmet proveded enough resistance so his head wasnt crushed.
