@@maxon1672 and no other protection... absolute genius... (just assuming cup was installed off camera, because, god knows, if you think you need to protect your head, your head thinks you need to protect those things first.)
I saw this video a couple of weeks ago. Last week when I was going ready to go out on my bicycle I thought about what you said about the double D-ring closure and how it forces you to adjust your helmet properly every time you put it on. So I checked my own strap and found it was a little looser than it should be. I adjusted it, and found it a little tighter than I'd like, but left it that way. 8 minutes later I was sitting on the side of the road, surrounded by shattered carbon and spitting my teeth into my hand after going face first into the A-pillar of a Hyundai at 30km/h (car came out of a driveway 3-4m ahead of me - I only had time to wince). The fact that you inspired me to adjust my helmet may have contributed to the fact that apart from some dental damage, all I have are a few bruises from this encounter. Thanks!
What kind of helmet type did you have? I know that the full face is the best option but god dang do those jet ones look sweet. But their cool factor definitely clashes with thoughts on safety and how eating teeth for lunch doesn't sound very pleasant.
I'm new to motorbikes and when I went helmet shopping the guys in the store made a point of informing me about the superiority of a DD closure. They mentioned the fact you have to adjust for tightness every time but I'm also now aware they're very much not going to break. Thank you.
And now, 10 months later; how often did you not tighten it correctly for the "short rides", for the "I'm only around the corner" Stuff, for the "Yeah, yeah, I just ride down the street"? ;D
"This account has been terminated for violating RUclips or Google's Terms of Service." Now Im really curious as to what RepentandbelieveinJesusChrist5 said.
“HEY! Wanna watch a video about D-rings?” NO, that sounds boring AF! “Wanna watch an F9 video about D-rings?” Yes, yes of course, I’m sure it’ll be interesting…
@@wdefghjuefhdegtfthtgf1351 As a Canadian I can confirm this. We're not known for producing comedians, I can't think of a single Canadian comedian who made it in America.
Safer? er not exactly, rings are overkill as are the mag thing and sliding clasp. the point here is they need to be done up right, the rings are more likely to be done up correctly. BUT F9 is trolling us. I'd never go back to the rings, sliding clasp is so convenient to use. Just as easy to snug up as not, rings were always a bit of fiddle especially with a thick tube neck warmer over the top. tearing your head off harder is not what i'd think of as safer tbh.
I do materials testing for a living, and I love the simple, cheap and effective (albeit not accurate, but definitely representative) approach. Great stuff guys!!
I was thinking about how it would be inaccurate due to the increased mechanical advantage as the arms of the jack get closer together, but if anything that just shows that the double d ring is even stronger than the "data" suggests...
The best argument for alternatives to the D-rings may be, as you said, protecting motorcyclists from ourselves. How often does a rider neglect to fasten a D-ring strap? Maybe the safest fastener is whichever one that a given rider will fasten every single time they get on their bike.
idk about you but my head and neck size doesnt vary much. one of the other ideas would've been fine if they were alsp made of metal. the only reason the d survived is because metal
@@Notred1775 I have a micrometric one, but it is made out of metal. Wonder how big of a difference it makes compared to the plastic ones. It has to be quite significant though.. considering the other is.. plastic.
@@Luggruff I've just bought a HJC i71 and (my fault) I thought it was a double D and instead is micrometric... I never had this before and I'm considering to returned or change it for another helmet. It's also a plastic one, I don't like it at all...
I always try to buy helmets with the D-rings. Sometimes I've been forced to buy another system, when a helmet was too good in other ways to pass up. BUT I always lamented the absence of D-rings. Some people find the D-rings fiddly, but I find it the easiest to deal with - the other systems are fiddly and you have the hassle of trying to adjust the constantly slipping strap adjusters. Weirdly I've noticed D-rings tend to come on the very cheapest helmets AND the most expensive - it's the inbetweeners that insist on putting these other crap buckles on their helmets... Great Vid - Cheers FortNine.
I JUST replaced my $40 Bell Qualifier with a year old on clearance Schuberth C3 Lite. It's got that micro metric ratchet, and yeah it's annoying in how it tightens! Theoretically it's faster, but I set it so fully seated is too tight, so I can click it a notch or two tighter before adjusting it again. But just in regular use I can click it too far, have to release it, and click it closed again. Not really faster! But the Schuberth C3 is literally tens of decibels quieter than that Qualifier. hfs, I did not notice how loud it was until I got a bike that wasn't obnoxiously loud itself.
that's true! i've noticed that with a lot of products and things that come in a range of quality. And the manufacturers will goof off and "experiment" with their mid-range things. So if both the cheapest AND the most expensive versions share a part, it's probably a decent part.
Absolutely love it, question everything, don't just except old standards because they've been around forever or new tech bc it's new. He really objectively looks into all of it.
There is one downside to the double D-ring buckle. The strap is dragged over metal edges every time you engage and disengage it, so strap wear is a factor. Good to know it holds so well, though.
The straps tend to be high quality even on cheap helmets pretty consistently at this point. I've only seen that be an issue in some very cheap bicycle helmets.
Thanks for interesting videos! I had my first JET-helmet 1968 and it had Double D-rings. Then I have had more modern locking technics. However - few years ago I bought a modern but retro style Jet-helmet with double D-rings. This helmet was used only a few occasions as I prefer integral helmets but this time it was a slow bike and it was sunny weather and the style looked autentic vintage-like. Almost 2 yeras ago I had an accident by driving into the green grassy strip along the road. The speed was 45-50 km/h with my renovated to state as new Husqvarna from 1953... Oh shit I thought - I have been into enduro in the eighties so I'll handle this. Next moment the bike just disappeared from me and I counted 3 full loops in the air, and only a half 4:th loop then I hit the ground on my back. I lost all breathing air but was alive. I got no air to breath so I first checked my fingers - I could feel all of them. I got of my gloves and the fingers opened the double-D-ring lock autonomously.... amzing - this just happened by it self. With full breathing capacity I just laid down there for some minutes. I tried to remember when it was the last time I had a double D-ring helmet. Then I wondered why none of the cars were stopping and check if I was OK. I found that the side of the road was a long and fairly steep slope. I turned around and I saw the shining blue bike several meters above me on the grassy slope. As soon I reached the roadside I got help. But - I am still amazed that the body can learn things and then perform them just by itself!
All I had running through my head this entire video was the image of Marco Simoncelli's helmet rolling away from him on the track, and how horrified I was to watch that back in 2011. The force of the impact his helmet had to take to come flying off is just unreal, as demonstrated here in this video. Truly a tragedy- RIP Super Sic :(
Sure if you're a racing rider that might be important. But for everyday riders the strap mechanism is irrelevant, all of them are more than safe I mean if you're 200 mph on public road then maybe you shouldn't have a license to begin with
@@ioandragulescu6063 because most of the time it is, when they release a new phone it's almost always better than before, same with cars, bikes, tech and most everything else
@@AstoundingAmelia right and on top of the faster procesing power/memory has a gazilion cameras, a boatlod of "features" like fingerprint sensors and face recognition and a ton of bloatware that most people want removed ... yeah, good analogy. Same with cars and bikes, more electronics and modes that serve little to no purpose, touch surfaces (for cars) that even reviewers hate lately, matrix headlights with auto high beam that blind incoming drivers on anything BUT a straight road and on and on. Prices go up, reliability down and let's not even talk about repairing them... yey progress !!
Remember everyone: Boots on, jacket on, gloves on, helmet..... gloves off, helmet on, gloves on. This is what the "double D" means to me, I swear it's every time I stop.
I've long believed the ability to do up a DD with your gloves on is the mark of an accomplished rider lol. But my latest lid has the ratchet too, and it is pretty awesome to use.
Interesting - I have two helmets, one with the old school D-rings, and one with the sliding ratchet. I prefer the ratchet as quicker and simpler - I had no idea the D-rings might still be a better solution.
I have same. I have never and will never wear the ratchet on the highway. The D-rings have always felt safer because they pulled tighter every time and there was no quick release.
the only reason you think it takes longer, is because you're needlessly unbuckling the dd buckle. Just slide it to it's stop by pulling the tab. If the strap isn't long enough, it's a design flaw, or you have monster neck and small head.
I too have a ratchet fixing helmet. It is easy to sinch tight and is the only system that you can sinch tight and remove with gloves on. How ever this video proves that although you can only fix and remove D-ring helmets with your gloves removed they are safer...
Never had D-ring helmets. Had helmets with a sort-of miniature seat belt lock, and currently one with a fully metal micro-ratchet-style quick release thingamabob. They're awesome! 😁
All of the "high end" racing helmets I had (Arai/Shoei) have the double D. But thats because these were also used by amateurs and pro's racers and, as stated in the video, the double D's are mandatory all over the world.
I've definitely seen the mini seatbelt style but it's not in this test. Not sure if they are officially stronger than the DD but I'd be interested in seeing as they probably look the most robust of not the DD
You made your point of view clear and sensible. Double D are probably a little more efficient and are the only way to go if you want track (in France). But the reasons is more because it is a standard that track emergency people are trained to. As any gear is much better than no gear, any helmet is better than no helmet...whatever the type and locking style. I would like to see what is the resistance of the other end of the strap too. I reckon the strap will break off the shelves well before any strap locking system...
I feel I should point out that, while ultimately proving what is to be expected, that the test measuring procedure is flawed. Using a torque wrench on the jack to obtain your values will not be consistent unless every failure occurs at exactly the same height of the jack extension. Due to the geometry of the scissor jack, the further it is extended, the less torque is required to be applied to the drive screw. The data might be able to be corrected by measuring the height of the jack at failure, in addition to the torque value on the screw, and extrapolate the data across the Jack's geometry mechanical advantage curve.
@@mgkleym Except this time the day didn't necessarily end. It probably did, but due to flawed testing methodology we don't know. What it did show fairly definitively though is that the dick clip is a terrible option.
@@RaghavSatya The jacks are in very similar positions before tightening started, and the straps look similarly identical as far as initial fitment is concerned. Any difference with this is ultimately negligible
@@RaghavSatya I believe they did reset it, but they didn't show it from the lowest position for every buckle because it would take too long for some of them. Since the buckles happened to have progressively more resistance, it kinda looked like they've started from where the previous buckle snapped off.
I like my ratchet buckle. It's adjustable, convenient, and I'm not convinced there's much additional safety to be had in a stronger buckle. I think if that's the failure mode then I'm not very likely to survive anyway.
The test is flawed, anyway. All were plastic except the double D. Let's try it again with plastic double Ds and see what happens. I'm betting my life savings it will break first, maybe second. All this video proves is that steel is stronger than plastic.
@@Zw1d are we comparing which mechanism is the most durable or what's available on the market? If it's the latter then yeah it's reasonable, if the former the test is flawed.
My helmet has a ratchet connector and I like it due to the ease of use. But I always check that the strap is tight and I agree that this is the most problematic issue on helmet wear. Thx for your insight.
@@coastaku1954/videos is this double d elitist right in this very room right now? this video is just educational, honestly i would trust ratchet with my very own life but i wouldnt do so on a clasp in the end what really matters is that the buckle is on, its fast, easy, and fastened
I dont drive a motorcycle and never plan on doing so, but i enjoy watching the videos just bc Ryan. I would even watch him review different cobblestones
According to ECE The retention system test involves placing the helmet’s retention straps under load in tension. For this test the load is progressive; first a load of 22.7 kg (49.9 lb.) is applied for 30 seconds, then it is increased to 136 kg (299.2 lb.) for 120 seconds, with measurement of the stretch or displacement of a fixed point on the retention strap from the apex of the helmet. Some new standards in FMVSS 218 will go into effect in May 2013.
My main concern with Fidlock is that sometimes when the clip connects, it is in a metastable position that *seems* to be done up but it isn't actually seated properly for whatever reason. The moment the strap is tugged, it releases. The potential for a metastable situation is the epitome of Murphy's Law - there's a nonzero chance that if the rider doesn't check that it's done up after hearing the 'click', every time, it might be in that metastable position during a crash. I have a helmet with Fidlock and I've made it a personal habit to always give the strap a tug/wiggle to check that the strap has, in fact, connected itself properly. Sometimes it has not.
Personally I prefer the ratchet mechanism. It has 85% of the strength of the double D rings, is always tight, is way faster and can be done up and undone with gloves on. I've found with double D rings it's possible to lock them too loose and then you have to faff about with your gloves to adjust it or even worse you don't get the ring order right and then it's basically useless. The ratchet is literally foolproof and less likely to decapitate you.
Полностью поддерживаю. Самая лучшая застежка из всех. Dring может и самая прочная, но при всей этой избыточной прочности, наиболее дурная в эксплуатации.
@@someguy5035 You're skilled enough to handle it with a single hand? I'm impressed. Still, added to the time needed to decelerate, four seconds take the glove off, one second to strap it tight, another 4 seconds to put the glove back on. Against a single second while riding with a single hand that I can do when I fully forget to even strap it due to a distraction when I'm putting my helmet on. In addition, rarely if ever is a traffic light, that I encounter, longer on red than I would need for all that, so I'd have to actually stop on the side of the road to not hinder traffic. Ratchet strap is my preference, for the obvious reason that I'm an idiot that sometimes forgets to strap it. The 15% loss is a risk I'm willing to take if that means comfort and the ease of use WHILE gloved is higher. Everyone has their preference, I'm just arguing from my point of view.
As a long-time motorcyclist, this came as a surprise. A racing scooter friend of mine (has a Lambretta which tops out at 100mph {160kph}) told me that the scrutineers will instantly reject any rider whose helmet doesn't have a double "D" fastening. I thought it was because the DD was easier to release if the rider was spark-out on the floor after an accident but *NO,* it's because the DD is stronger than the webbing. The things I didn't know I didn't know.... Thank you for risking life and limb for us & bringing it to our attention.
Absolutely love it, question everything, don't just except old standards because they've been around forever or new tech bc it's new. He really objectively looks into all of it.
I'm so glad you just put out this video... I have a backward facing GoPro on my daughter's motorcycle and she just got in an accident and you can see where the helmet strap clearly held the helmet on her head as she was flying through the air.... If that helmet strap wasn't tightened correctly the helmet would have flown off before hitting her face on the ground with the initial impact. Thank God for the evolution of these buckles 🙏
Hope all is well, but I'm pretty sure the point of the video was that these new buckles are worse then the REALLY OLD set of D rings. Meaning it's a gimmick and waist of money when you could use 2 D rings and be safer. Over engineered was the point. K.I.S.S method is best method.
@@mickeyhavoc939 I really don't understand why stronger means safer. I think all of these buckles are safe enough. Ryan even says in the video that if it's too strong it would just rip your head off and to me that doesn't sound very safe.
@Pauline Weinberger She's fine (she races 50cc dirtbikes) I just wanted to point out how important this strap truly is. It possibly saved my daughter's life that day, she highsided and flew 10-15 feet landing directly onto her face and chest on an extremely hard packed track. She wears full gear all the time so she got up and finished her race 🏁 she was crying but still finished the race 💪
@@mickeyhavoc939 after what I saw on her camera I wouldn't use anything but the 2 D-ring setup.... If you alter your strap in hopes to buckle faster or easier it's a death sentence IMO
You need to send this to a RUclips channel called "How not 2 highline". He is the expert at breaking buckles, ropes, etc AND knows how to do it dynamically as well.
@@minarchisttrucker2775 I love the echo quick release. Been running it for at least 15 years. Easy to use with gloves. The newer ones can easily be tightened\loosened as well
@Jessica💋 Sweety Hotgirl - Vlogs exactly! I've run the Echo quick release for Years... Which is why I'd love to see it tested the same way. Especially considering their claims.
@@Miata822 Agreed; people don’t talk about it enough. He mentioned something about snug-fitting helmets being comforting at higher speeds in a helmet review a while back, but if memory serves, the comment was more about the fit feeling safer, rather than actually being safer.
@@Miata822 Sorry, but I can't ride a god damn lick with a migraine from the helmet... Maybe I'm missing something, but a proper fit to the head-gear DOES actually feel better (to me at least) than a poor fit. I'm just not sure what the hell you're smoking... Though I will agree, "Proper helmet fitment" is a great subject that not enough people ever talk about... AND I'm the kind of guy who "road-trips" for upwards of two days on the saddle before he takes a night to "camp out"... whether hotel or tent. ;o)
Wow! I now have a new found appreciation and respect for the good old double D buckle. That will help me stay calm and relieve frustration the next time I forget to buckle my helmet before putting my gloves on.
Controversial opinion but I'd still rather my ratchet over the double D-rings as they're so much faster and easier, if I suddenly have 555lb of force exerted on my head pulling my helmet off, I've got bigger problems than whether the strap snaps or not.
@@mariodonkartworks I have been riding for over 4 years with a ratchet strap, never had it undone accidentally. It's the most common here in the Netherlands as well
Arguably, and as mentioned, for the DD strap break you're already dead or decapitated. I wouldn't use the plastic 'Dicky' on a motorcycle helmet but the ratchet is by far my favorite. It can be adjusted near perfect and due to the teeth it has some space to adjust automatically if you put on some underchins. More importantly, it can easily be operated with gloves and takes a second to do/undo. This part being important when using your bike for daily errands with constant on and off. The best example I can think off the most prevalent and careless riders - city food deliveries that boomed due to Rona. If their helmet is tightened it's a ratched, while DD's are usually just flapping in the wind. When shopping for helmets I actively avoid DD system. I would consider the German overengineered one too.
@Capt Shiny 1. The relevant metric is when your neck snaps and not when you get decapitated. 2. The amount of force required to snap someones neck varies from person to person. So I’d rather have the strap fail before anyones neck could snap as I don’t know when my own neck will snap.
Problem with all the others...they can be released in the crash without actually failing. A good hit to the head..and a slight twist can have a jacket coller release a ratchet... I know this from experience. You ride you...you decide your risk. DD ftw in my book. Ill use nothing else. Id rather lose a few seconds of my life securing my lid than lose the rest of my life being impatient.
Excellent video, as normal. Correct, the first lesson I had as a motorcyclist was how to put on a helmet. After watching me struggle with the D rings my pal said. "Don't undo them, make it slack and hold it to the chin bar then tighten it up when it's on." I always do that and have never owned a helmet that it did not work on. Incidentally, I cringe when even professional racers fiddle around with rings. I want to shout THERE IS A BETTER WAY!
Nice. That's a life hack right there. I've got a helmet with ratchet fastener, the mechanism is too big it makes my throat hurt. I will get a Double D ring for the next helmet.
ECE helmet safety certification has a point about neck straps where at a certain force they need to snap to avoid decapitation if the rider slides and catches a curb edge with his helmet. Really don't see a problem with ratchet straps snapping, that's what they were designed to do.
I hate the double-D Ring because I can't feel them in gloves and they're a pain in the SSS! So I use Quick Release Ratcheted Stainless Steel Helmet Chin Strap instead and they've never failed, yet easy to operate!
Those DD rings are also on the safety helmet I wear for horseback riding. That reminds me, the leather paddock boots I wear for English riding are also my motorcycle footwear of choice. Usually with a pair of half chaps.
I had a mini seatbelt type of helmet latch before. If I wasn’t paying attention it would pinch me when clicking it. It’s double Ds for me. They work best.
what do you mean, metal? that serrated part that broke in video - it's always metal. Never seen a helmet with a plastic one, though I never had a premium helmet, all of mine were 100-200 usd. red releasing part is plastic, but it's not one that failed
@@tomekvilmovskiy6547 if you rewatch the video you will notice that the part that failed is out of plastic. Most budget helmets and even some premium ones use these plastic ratchets
@@yasc_ rewatched a few times: I see that the long metal buckle is broken. It could damage any plastic parts around after was broken itself, but for sure, broken plastic is unable to damage the metal buckle. So i made a conclusion, metal failed first.
You know what? Since I am not a motorcycle gear manufacturer, I will remain subscribed and even hit the like button! And what you gonna do about it, Ryan?
I don't ride motorcycles, but mountain bike a lot. I'm not sure why we moved away from D rings and I'm sad about it as I much much much prefer them (had them on my older full face helmet). I prefer fidlock over the regular clip but all of them suck compared to D rings IMO: - I don't have to think about my facial hair with the D ring - The D ring is always well adjusted - My facial hair gets stuck in the clips a lot - The straps on the clips get loose over time, and re-tightening the straps is a pain in the butt because they put rubber holders around the straps, puffy pieces so it's softer against the skin and they make the adjustments super tight fitting so that (I assume) they don't come loose as often (but that just makes them harder to adjust)
I have a confession, I don't own a motortcycle, Im not really interested in motorcycles. But I find RyanF9 very entertaining, so much so I binged watch episodes from 4 years ago.
Great videos man. As someone somewhat new to riding but already obsessed.... I am finding all the insight incredibly valuable. Thanks for taking the time!
I ride mostly off road, and the ratchet strap on my helmet lets me take it on and off quickly when stopping to rest to cool my head off. I consider it and my camelback 2 pieces of gear I wouldn't ride without. While other riders are sweating it out because its inconvenient to get the helmet off and get the water bottle out, I can do it in whenever I need. And the ratchet strap is adjustable, I snug it up every time I put it.
Other than an old RST which had a mini seatbelt type connection that they inherited from AGV, every lid I've had has been double D ring. There's just something reassuring about it.
One thing to note is that the DD is the only metal fixing in the test. Perhaps you should repeat it with a pair of plastic DD for a comparison. I ride a 'solid' Arai with DD and a flip up Schuberth with a ratchet fixing. In an accident in 2017 my AGV with a ratchet strap stayed on despite headbutting a car windscreen.
Interesting; every helmet I’ve had in the UK has the ratchet type buckle - including some very expensive, non-European made helmets (Shoei etc)… You glossed over a key point though - like you said, I’d pretty definitely want the buckle to open/break if subjected to those kind of forces, rather than imparting them onto my neck… no?
I'm confused. The mainly used lock here in my area works like a seat belt buckle, only smaller. I'm sure the are as strong as D-rings, but way more comfortable. I lock my helmet with just one hand Riding bikes for over 30 years now and I was not aware that double D-rings still exist. Nobody I know buys/uses them.
@Capt Shiny I'm going on faith that Schuberth has done their research. It's got a 4 way strap vs a typical 2 piece strap. The more you pull on it, the more it cinches the base of the helmet to your head. I cannot put on a D ring helmet with my gloves on, otherwise I wouldn't care. It may not be difficult to you, but I guess I'm inferior to you as a person, which is what I'm guessing you were hoping I'd say to you.
@@XtreeM_FaiL The modular helmet with ratchet strap means I don't have to take my glasses off to get the helmet on and off. And I don't have to take my gloves on and off to fiddle with the strap. I don't have specific scenarios in mind, but the time I spend with my C3 vs my former Arai non-modular helmet has been cut down by a factor of four.
@@XtreeM_FaiL It's a modular helmet so I can get it on and off without removing my glasses. The strap is just one more reason it's much faster than other types of helmets to put on and remove.
I had an accident. One of my arms was broken in it, so I couldn't take off my gloves, and being gloved couldn't unbuckle my double-D strapped helmet. Luckily a motorcycle rider stopped and helped me to unbuckle the helmet. So all in all that also should be considered when talking about the pros and cons of each fastening system.
I've had the double D's on every helmet I had until my last one, that is a Caberg that now has a ratchet and double D's combination for adjusting. Many EU helmets here in Europe now use the ratchet and double D's in combination. It is 10 times more user friendly and If you get to the level of impact and twist on your helmet that the ratchet fails...than you have much bigger problems....your neck will be broken before the ratchet fails.
@@TimpaNidevo , yes I did. Want to bet you can hang a 80kg adult male by one of those nylon straps, give him a drop like they used to do with hangings and they will brake the neck before that nylon breaks ? Motorcycle accidents are not slow controlled incidents, they are quick and violent.
@@TimpaNidevo And another thing, the DD's are overkill and not user friendly...it's 2021, e have better tech. Top helmet manufacturers don't use ratchet systems now because they are idiots, they use them because they are better. I'm amazed one can still buy an expensive helmet with only the D's as a locking mechanism. Old habits die hard I guess...and bikers are some of the most resistant to change people on the planet.
@@valiyzf600 @valiyzf600 We all know what the current year is. Something being new does not mean it is better and something being old does not mean it is worse. The idea of D-rings not being user friendly is laughable, it takes a few seconds to loop the strap through them. I agree that top helmet manufactures aren't idiots, you'll note that those same manufactures offer D-rings and alternatives. The evidence in this video shows that D-rings are superior, do you have any evidence to the contrary?
@@TimpaNidevo D-rings are not superior, they just have more strength. That does not equate that they are superior. The question is if that strength is needed with the price of a more fiddly setup. It takes 5-7 sec to lock my old helmet with D-rings, maybe a few more if it doesn't feel rightly adjusted from the start, and preferably all of this without gloves. It takes under a second with gloves to do my new one and it's perfect every time, because I only need to adjust it once. The only reason manufacturers offer both versions is because bikers and people in general are creatures of habit and/or regulations that are not updated in some parts of the world.
Interestingly enough any buckle but the double D is common here in Europe. I had to place a spacial order for the double D bucket for my Schuberth C4 Pro. Most of my biker friends give me a strange look when they see me putting on the helmet and fixing it with the double D, but your video proved (again) that I made the right choice and the extra 50 Euros are worth it.
i remember having a stretch armstrong; i remember playing with it in my kitchen, listening to elton john....weird memory association, but, thank you for the trip down amnesia lane.
I have the shoei gt air 2 with the metal ratchet. I quite like it I think it is supposed to be easier to undo with gloves on. My Arai RX7 Corsair has the double D as has every other helmet I’ve ever had and it is a great and simple solution
Cool topic, interesting experiment (y) I've always liked the DD better. As for the protection you guys used. Forget plexi glass. It is rigid and easy to break. Polycarbonate sheets are a bit more expensive but there is a reason they are used as aeroplane windows.
@@MrVTeta nope. Acrylic is different from polycarbonate. They are forms of polymers but chemically different and different in the process of making them. Polycarbonate is stronger.
@@GrimYak You are right, this brand is not sold here and I confused plexiglass with lexan which is polycarbonate. Polycarbonate is indeed stronger. Anyway, even for polycarbonate the sheet they used was far too thin for this experiment.
Hi FortNine and thank you for these awesome videos. I must've watched them many times by now. In one video, I believe Ryan mentioned the motorcycle clutch handle covered with 4 fingers "which is bad for reasons I'll explain in a future video". Can you please make such a video? I can't seem to find one. I'm curious about both front break and clutch covering. Thanks.
you can find videos about it from Brettkacs one of his recent video explains it why. If in not mistaken the title is 2 errors that self taught adv riders do...it does covers the topic for street riding as well.
@@viviansee9989 thanks for replying to me. I will take a look, as I've been following him for a while too. I've been riding long enough to judge for myself which works and which doesn't. The question at hand, was mostly for the "covering" of the clutch handle with 2 fingers as there are numerous ways that this can go bad, especially when doing that in first gear. Thus, four fingers will provide the much needed fines, without accidentally crushing your fingers(it can however work with 2 fingers, in upper gears, but feels redundant). Covering the break leaver with 2 fingers is justified and I have been using it for years. 🙂
@@viviansee9989 I saw the video that you mentioned. He uses 3 fingers(4 wouldn't hurt anything in technique, since the smallest finger doesn't do much of anything) from an ADV riding perspective which is a completely different situation than that of riding on the streets and also because he will have to stand up, on the bike, most of the time when on off-road. His colleague with 2 on the clutch and 1 on the front brake, well... I don't want to see him do an emergency breaking demonstration 🙈 but then again, it's off-road so he should be safe.
@@clue0001 I myself have been using clutch with two fingers with my thumb on the hon which fortnine mentioned in one of his very early videos for city riding techniques. I found it useful as it gives me enough reaction time to play with the clutch when I need it. I don't worry about using two fingers or any pinching when going into first gear as well. I use two fingers for braking as well, that way I don't lose grip for either handle bars. Trust me, I live in city that is always in constant heavy traffic with car having bad driving habits so always having contact with either control allows me have better control over my speed and flexibility to warn people of my presence when I lane filtering which is somewhat allowed in my country. I found gymkhana and adv techniques are useful to me but not necessarily useful to everyone so that is why we call riding an art, everyone have there own gloves that they fancy.
For sure! It was roughly 1.5 ft-lb less strong, which is a trade-off I'm willing to make for sure. (Fidlock offers samples of their products. I think I'm going to try to request a couple and try it on one of mine.)
True! As long as it's stressed in the right direction, the aluminum fidlock is nearly as strong as a double D. Though it's a little unnerving how you can knock it open with one finger. ~RF9

I saw this video a couple of weeks ago. Last week when I was going ready to go out on my bicycle I thought about what you said about the double D-ring closure and how it forces you to adjust your helmet properly every time you put it on.
So I checked my own strap and found it was a little looser than it should be. I adjusted it, and found it a little tighter than I'd like, but left it that way.
8 minutes later I was sitting on the side of the road, surrounded by shattered carbon and spitting my teeth into my hand after going face first into the A-pillar of a Hyundai at 30km/h (car came out of a driveway 3-4m ahead of me - I only had time to wince).
The fact that you inspired me to adjust my helmet may have contributed to the fact that apart from some dental damage, all I have are a few bruises from this encounter.
Thanks!
What kind of helmet type did you have? I know that the full face is the best option but god dang do those jet ones look sweet. But their cool factor definitely clashes with thoughts on safety and how eating teeth for lunch doesn't sound very pleasant.

Safer? er not exactly, rings are overkill as are the mag thing and sliding clasp. the point here is they need to be done up right, the rings are more likely to be done up correctly. BUT F9 is trolling us. I'd never go back to the rings, sliding clasp is so convenient to use. Just as easy to snug up as not, rings were always a bit of fiddle especially with a thick tube neck warmer over the top. tearing your head off harder is not what i'd think of as safer tbh.

The best argument for alternatives to the D-rings may be, as you said, protecting motorcyclists from ourselves. How often does a rider neglect to fasten a D-ring strap? Maybe the safest fastener is whichever one that a given rider will fasten every single time they get on their bike.
well the ratchet clip you also have to tighten every time, thats why its so long because you put it in untill the point its tight

I always try to buy helmets with the D-rings. Sometimes I've been forced to buy another system, when a helmet was too good in other ways to pass up. BUT I always lamented the absence of D-rings. Some people find the D-rings fiddly, but I find it the easiest to deal with - the other systems are fiddly and you have the hassle of trying to adjust the constantly slipping strap adjusters. Weirdly I've noticed D-rings tend to come on the very cheapest helmets AND the most expensive - it's the inbetweeners that insist on putting these other crap buckles on their helmets... Great Vid - Cheers FortNine.
I JUST replaced my $40 Bell Qualifier with a year old on clearance Schuberth C3 Lite. It's got that micro metric ratchet, and yeah it's annoying in how it tightens! Theoretically it's faster, but I set it so fully seated is too tight, so I can click it a notch or two tighter before adjusting it again. But just in regular use I can click it too far, have to release it, and click it closed again. Not really faster!
But the Schuberth C3 is literally tens of decibels quieter than that Qualifier. hfs, I did not notice how loud it was until I got a bike that wasn't obnoxiously loud itself.
that's true! i've noticed that with a lot of products and things that come in a range of quality. And the manufacturers will goof off and "experiment" with their mid-range things. So if both the cheapest AND the most expensive versions share a part, it's probably a decent part.

There is one downside to the double D-ring buckle. The strap is dragged over metal edges every time you engage and disengage it, so strap wear is a factor. Good to know it holds so well, though.

Thanks for interesting videos! I had my first JET-helmet 1968 and it had Double D-rings. Then I have had more modern locking technics. However - few years ago I bought a modern but retro style Jet-helmet with double D-rings. This helmet was used only a few occasions as I prefer integral helmets but this time it was a slow bike and it was sunny weather and the style looked autentic vintage-like. Almost 2 yeras ago I had an accident by driving into the green grassy strip along the road. The speed was 45-50 km/h with my renovated to state as new Husqvarna from 1953... Oh shit I thought - I have been into enduro in the eighties so I'll handle this. Next moment the bike just disappeared from me and I counted 3 full loops in the air, and only a half 4:th loop then I hit the ground on my back. I lost all breathing air but was alive. I got no air to breath so I first checked my fingers - I could feel all of them. I got of my gloves and the fingers opened the double-D-ring lock autonomously.... amzing - this just happened by it self. With full breathing capacity I just laid down there for some minutes. I tried to remember when it was the last time I had a double D-ring helmet. Then I wondered why none of the cars were stopping and check if I was OK. I found that the side of the road was a long and fairly steep slope. I turned around and I saw the shining blue bike several meters above me on the grassy slope. As soon I reached the roadside I got help.
But - I am still amazed that the body can learn things and then perform them just by itself!

@serdy ximi and like he said in the video, the others are destined to not be set properly because people will inevitably make them far too loose
I have same. I have never and will never wear the ratchet on the highway. The D-rings have always felt safer because they pulled tighter every time and there was no quick release.
the only reason you think it takes longer, is because you're needlessly unbuckling the dd buckle. Just slide it to it's stop by pulling the tab. If the strap isn't long enough, it's a design flaw, or you have monster neck and small head.
I too have a ratchet fixing helmet. It is easy to sinch tight and is the only system that you can sinch tight and remove with gloves on.
How ever this video proves that although you can only fix and remove D-ring helmets with your gloves removed they are safer...
As he was turning that ratchet and hiding next to the cabinet, I kept thinking "ALL THE GEAR ALL THE TIME, RYAN."

You made your point of view clear and sensible. Double D are probably a little more efficient and are the only way to go if you want track (in France). But the reasons is more because it is a standard that track emergency people are trained to.
As any gear is much better than no gear, any helmet is better than no helmet...whatever the type and locking style. I would like to see what is the resistance of the other end of the strap too. I reckon the strap will break off the shelves well before any strap locking system...
Love the “safety” repositioning and add’ons after each test😅. As always fun informative video!
I feel I should point out that, while ultimately proving what is to be expected, that the test measuring procedure is flawed. Using a torque wrench on the jack to obtain your values will not be consistent unless every failure occurs at exactly the same height of the jack extension. Due to the geometry of the scissor jack, the further it is extended, the less torque is required to be applied to the drive screw. The data might be able to be corrected by measuring the height of the jack at failure, in addition to the torque value on the screw, and extrapolate the data across the Jack's geometry mechanical advantage curve.
At the end of the day all that really matters is did the buckle break before the strap. Its really a pass fail test.
I was also wondering why he didn't reset the jack for each test.
@@mgkleym Except this time the day didn't necessarily end. It probably did, but due to flawed testing methodology we don't know. What it did show fairly definitively though is that the dick clip is a terrible option.
@@RaghavSatya The jacks are in very similar positions before tightening started, and the straps look similarly identical as far as initial fitment is concerned. Any difference with this is ultimately negligible
@@RaghavSatya I believe they did reset it, but they didn't show it from the lowest position for every buckle because it would take too long for some of them. Since the buckles happened to have progressively more resistance, it kinda looked like they've started from where the previous buckle snapped off.
I like my ratchet buckle. It's adjustable, convenient, and I'm not convinced there's much additional safety to be had in a stronger buckle. I think if that's the failure mode then I'm not very likely to survive anyway.
Indeed. Schuberth uses ratchet buckles aswel, i think its nice that i can strap the helmet on the fly, if i somehow forgot to do it before i left
same, it's so fast and i'm pretty sure strong enough. I honestly don't think you could survive breaking the strap by applying 400kg with your neck.
The test is flawed, anyway. All were plastic except the double D.
Let's try it again with plastic double Ds and see what happens. I'm betting my life savings it will break first, maybe second.

According to ECE The retention system test involves placing the helmet’s retention straps under load in tension. For this test the load is progressive; first a load of 22.7 kg (49.9 lb.) is applied for 30 seconds, then it is increased to 136 kg (299.2 lb.) for 120 seconds, with measurement of the stretch or displacement of a fixed point on the retention strap from the apex of the helmet.

Thank you
In the end, even if you choose something he didn’t recommend, the fact that he gave clear information let’s you decide exactly what risk you choose.
My main concern with Fidlock is that sometimes when the clip connects, it is in a metastable position that *seems* to be done up but it isn't actually seated properly for whatever reason. The moment the strap is tugged, it releases. The potential for a metastable situation is the epitome of Murphy's Law - there's a nonzero chance that if the rider doesn't check that it's done up after hearing the 'click', every time, it might be in that metastable position during a crash.
I have a helmet with Fidlock and I've made it a personal habit to always give the strap a tug/wiggle to check that the strap has, in fact, connected itself properly. Sometimes it has not.

@serdy ximi woosh!
Personally I prefer the ratchet mechanism. It has 85% of the strength of the double D rings, is always tight, is way faster and can be done up and undone with gloves on. I've found with double D rings it's possible to lock them too loose and then you have to faff about with your gloves to adjust it or even worse you don't get the ring order right and then it's basically useless. The ratchet is literally foolproof and less likely to decapitate you.

@@someguy5035 You're skilled enough to handle it with a single hand? I'm impressed. Still, added to the time needed to decelerate, four seconds take the glove off, one second to strap it tight, another 4 seconds to put the glove back on. Against a single second while riding with a single hand that I can do when I fully forget to even strap it due to a distraction when I'm putting my helmet on. In addition, rarely if ever is a traffic light, that I encounter, longer on red than I would need for all that, so I'd have to actually stop on the side of the road to not hinder traffic.
Ratchet strap is my preference, for the obvious reason that I'm an idiot that sometimes forgets to strap it. The 15% loss is a risk I'm willing to take if that means comfort and the ease of use WHILE gloved is higher. Everyone has their preference, I'm just arguing from my point of view.

If that helmet strap wasn't tightened correctly the helmet would have flown off before hitting her face on the ground with the initial impact. Thank God for the evolution of these buckles 🙏
What exactly happened? What injuries did she sustain?
Hope all is well, but I'm pretty sure the point of the video was that these new buckles are worse then the REALLY OLD set of D rings. Meaning it's a gimmick and waist of money when you could use 2 D rings and be safer. Over engineered was the point. K.I.S.S method is best method.

A nice comfy helmet with a comfy strap is a poor fit. I wish Ryan @FortNine would do a video on proper helmet fitment.
Does your double chin change shape so often?
@@Miata822 Agreed; people don’t talk about it enough. He mentioned something about snug-fitting helmets being comforting at higher speeds in a helmet review a while back, but if memory serves, the comment was more about the fit feeling safer, rather than actually being safer.
@@Miata822 Sorry, but I can't ride a god damn lick with a migraine from the helmet... Maybe I'm missing something, but a proper fit to the head-gear DOES actually feel better (to me at least) than a poor fit.
I'm just not sure what the hell you're smoking... Though I will agree, "Proper helmet fitment" is a great subject that not enough people ever talk about...
AND I'm the kind of guy who "road-trips" for upwards of two days on the saddle before he takes a night to "camp out"... whether hotel or tent. ;o)
Wow! I now have a new found appreciation and respect for the good old double D buckle. That will help me stay calm and relieve frustration the next time I forget to buckle my helmet before putting my gloves on.
Controversial opinion but I'd still rather my ratchet over the double D-rings as they're so much faster and easier, if I suddenly have 555lb of force exerted on my head pulling my helmet off, I've got bigger problems than whether the strap snaps or not.
I was thinking the same
Agree.
Too seay to accidentally undo while riding
@@mariodonkartworks I have been riding for over 4 years with a ratchet strap, never had it undone accidentally. It's the most common here in the Netherlands as well
Arguably, and as mentioned, for the DD strap break you're already dead or decapitated. I wouldn't use the plastic 'Dicky' on a motorcycle helmet but the ratchet is by far my favorite.
It can be adjusted near perfect and due to the teeth it has some space to adjust automatically if you put on some underchins.
More importantly, it can easily be operated with gloves and takes a second to do/undo.
This part being important when using your bike for daily errands with constant on and off. The best example I can think off the most prevalent and careless riders - city food deliveries that boomed due to Rona. If their helmet is tightened it's a ratched, while DD's are usually just flapping in the wind.
When shopping for helmets I actively avoid DD system. I would consider the German overengineered one too.
If the strap is long enough you don't have to fully open it to take off the helmet and just pull it to tighten it.
@Capt Shiny 1. The relevant metric is when your neck snaps and not when you get decapitated.
2. The amount of force required to snap someones neck varies from person to person.
So I’d rather have the strap fail before anyones neck could snap as I don’t know when my own neck will snap.
@@XtreeM_FaiL exactly. That's the beauty of it. It's a lot quicker than other systems, many people just don't know that.
Problem with all the others...they can be released in the crash without actually failing. A good hit to the head..and a slight twist can have a jacket coller release a ratchet...
I know this from experience. You ride you...you decide your risk.
DD ftw in my book. Ill use nothing else. Id rather lose a few seconds of my life securing my lid than lose the rest of my life being impatient.
Idiotic comment. Kudos.
Excellent video, as normal. Correct, the first lesson I had as a motorcyclist was how to put on a helmet. After watching me struggle with the D rings my pal said. "Don't undo them, make it slack and hold it to the chin bar then tighten it up when it's on." I always do that and have never owned a helmet that it did not work on. Incidentally, I cringe when even professional racers fiddle around with rings. I want to shout THERE IS A BETTER WAY!
Nice. That's a life hack right there.
I've got a helmet with ratchet fastener, the mechanism is too big it makes my throat hurt. I will get a Double D ring for the next helmet.

ECE helmet safety certification has a point about neck straps where at a certain force they need to snap to avoid decapitation if the rider slides and catches a curb edge with his helmet. Really don't see a problem with ratchet straps snapping, that's what they were designed to do.
I think if you experience that kind of force on your head it'll break your neck anyways 😂
@@AggieRanger a broken neck is better than no neck.
@@matthewmaxwell-burton4549 The result either way is death so not really. Unless you care about having an open casket funeral 🤣
Er, he talks about exactly that point (at some length) in this video...
ECE say this.
"The strap shall withstand a tension of 3 kN without breaking."
If any other part break before that, then it is a fail.
I hate the double-D Ring because I can't feel them in gloves and they're a pain in the SSS! So I use Quick Release Ratcheted Stainless Steel Helmet Chin Strap instead and they've never failed, yet easy to operate!
I like the European/Canadian ratcheting buckle. So easy to get on and off. It was by accident I happened upon it and now I'll never change.
Can this be added to a helmet?
@@msvalina007 don't think so. I bought my first one from Canada then the second from the Netherlands. I'm in the US. Try crhomeburner
Another great class by the master, Ryan today. I always learn things I didn't know I needed to learn about. So much fun.
Those DD rings are also on the safety helmet I wear for horseback riding.
That reminds me, the leather paddock boots I wear for English riding are also my motorcycle footwear of choice. Usually with a pair of half chaps.
I had a mini seatbelt type of helmet latch before. If I wasn’t paying attention it would pinch me when clicking it. It’s double Ds for me. They work best.
You could've added a ratchet out of metal to the mix, like the ones used on the Shoei GT-Air 2
If I'm not mistaken, it is mandatory in the new European standard. So yea. That would have being nice.
I did not notice the first watch. But he did in fact use the plastic kind, as opposed to the metal one used on shoei's.
Thanks for pointing that out.
what do you mean, metal?
that serrated part that broke in video - it's always metal. Never seen a helmet with a plastic one, though I never had a premium helmet, all of mine were 100-200 usd.
red releasing part is plastic, but it's not one that failed
@@tomekvilmovskiy6547 if you rewatch the video you will notice that the part that failed is out of plastic. Most budget helmets and even some premium ones use these plastic ratchets
@@yasc_ rewatched a few times: I see that the long metal buckle is broken. It could damage any plastic parts around after was broken itself, but for sure, broken plastic is unable to damage the metal buckle. So i made a conclusion, metal failed first.
Wow! I bought a Smith mainline fullface mtb helmet a couple days ago, happy it comes with d rings.
Absolutely brilliant! Thank you for your civil service to ALL riders. You served up an ace, let’s see how the manufacturers respond…
What a stupid comment 🤣
You know what? Since I am not a motorcycle gear manufacturer, I will remain subscribed and even hit the like button! And what you gonna do about it, Ryan?
I don't ride motorcycles, but mountain bike a lot. I'm not sure why we moved away from D rings and I'm sad about it as I much much much prefer them (had them on my older full face helmet). I prefer fidlock over the regular clip but all of them suck compared to D rings IMO:
- I don't have to think about my facial hair with the D ring
- The D ring is always well adjusted
- My facial hair gets stuck in the clips a lot
- The straps on the clips get loose over time, and re-tightening the straps is a pain in the butt because they put rubber holders around the straps, puffy pieces so it's softer against the skin and they make the adjustments super tight fitting so that (I assume) they don't come loose as often (but that just makes them harder to adjust)
Ryan F9: "...or are double D's just too classic?"
Ryan F9: *looks at the camera and smirks*
🤣
Yeah, and where are his hands...?
I have a confession, I don't own a motortcycle, Im not really interested in motorcycles. But I find RyanF9 very entertaining, so much so I binged watch episodes from 4 years ago.
Great videos man. As someone somewhat new to riding but already obsessed.... I am finding all the insight incredibly valuable. Thanks for taking the time!
I ride mostly off road, and the ratchet strap on my helmet lets me take it on and off quickly when stopping to rest to cool my head off. I consider it and my camelback 2 pieces of gear I wouldn't ride without. While other riders are sweating it out because its inconvenient to get the helmet off and get the water bottle out, I can do it in whenever I need. And the ratchet strap is adjustable, I snug it up every time I put it.
DD is just as fast to take off.
5-10s. slower to strap on.
Easy solution is to get a quicker bike to compensate that.
@@XtreeM_FaiL A DD is a 1978 XR75 and a quick release is a 2022 250R by comparison..
Other than an old RST which had a mini seatbelt type connection that they inherited from AGV, every lid I've had has been double D ring. There's just something reassuring about it.
I had an AGV helmet with that thing and I wondered what happened to them
One thing to note is that the DD is the only metal fixing in the test. Perhaps you should repeat it with a pair of plastic DD for a comparison. I ride a 'solid' Arai with DD and a flip up Schuberth with a ratchet fixing. In an accident in 2017 my AGV with a ratchet strap stayed on despite headbutting a car windscreen.
Interesting; every helmet I’ve had in the UK has the ratchet type buckle - including some very expensive, non-European made helmets (Shoei etc)… You glossed over a key point though - like you said, I’d pretty definitely want the buckle to open/break if subjected to those kind of forces, rather than imparting them onto my neck… no?
Shoei moved from rathet to double d in new helmets like in GT-air 2.
Maybe. If something is trying to rip your helmet off, it might also continue to inflict serious damage to your head once the helmet is ripped off...
Just what I was thinking TBH.
I love the science! Each time I learn something new on this channel!
I'm confused.
The mainly used lock here in my area works like a seat belt buckle, only smaller.
I'm sure the are as strong as D-rings, but way more comfortable. I lock my helmet
with just one hand
Riding bikes for over 30 years now and I was not aware that double D-rings still exist.
Nobody I know buys/uses them.
I always felt the D rings were the safest, great to see scientific proof. Thank you FortNine crew!
I have seen one other connection which wasn't tested in this video but should work faster and better and that connection is a miniature seat belt.
I'm not giving up my burton style ratchet on the Schuberth I have. It's the fastest on/off helmet I own and I can leave my gloves on.
Why it is so important to have gloves on?
What do you do with gloves on anyway?
@Capt Shiny I'm going on faith that Schuberth has done their research. It's got a 4 way strap vs a typical 2 piece strap. The more you pull on it, the more it cinches the base of the helmet to your head. I cannot put on a D ring helmet with my gloves on, otherwise I wouldn't care. It may not be difficult to you, but I guess I'm inferior to you as a person, which is what I'm guessing you were hoping I'd say to you.
@@XtreeM_FaiL The modular helmet with ratchet strap means I don't have to take my glasses off to get the helmet on and off. And I don't have to take my gloves on and off to fiddle with the strap. I don't have specific scenarios in mind, but the time I spend with my C3 vs my former Arai non-modular helmet has been cut down by a factor of four.
@@421CentralIowa How is chin strap's locking system affect glasses in anyway?
Oh, you talk about the helmet only.
@@XtreeM_FaiL It's a modular helmet so I can get it on and off without removing my glasses. The strap is just one more reason it's much faster than other types of helmets to put on and remove.
I had an accident. One of my arms was broken in it, so I couldn't take off my gloves, and being gloved couldn't unbuckle my double-D strapped helmet. Luckily a motorcycle rider stopped and helped me to unbuckle the helmet. So all in all that also should be considered when talking about the pros and cons of each fastening system.
What happened to your other arm? Did you lost it, because undoing DD with one hand ain't hard at all.
@@XtreeM_FaiL are you blind or something? I said I couldn't unbuckle the helmet. Obviously that was with my unbroken arm
I've had the double D's on every helmet I had until my last one, that is a Caberg that now has a ratchet and double D's combination for adjusting. Many EU helmets here in Europe now use the ratchet and double D's in combination. It is 10 times more user friendly and If you get to the level of impact and twist on your helmet that the ratchet fails...than you have much bigger problems....your neck will be broken before the ratchet fails.
Did you watch the entire video? The nylon strap is designed to snap at lower than neck breaking force.
@@TimpaNidevo , yes I did. Want to bet you can hang a 80kg adult male by one of those nylon straps, give him a drop like they used to do with hangings and they will brake the neck before that nylon breaks ? Motorcycle accidents are not slow controlled incidents, they are quick and violent.
@@TimpaNidevo And another thing, the DD's are overkill and not user friendly...it's 2021, e have better tech. Top helmet manufacturers don't use ratchet systems now because they are idiots, they use them because they are better. I'm amazed one can still buy an expensive helmet with only the D's as a locking mechanism. Old habits die hard I guess...and bikers are some of the most resistant to change people on the planet.
@@valiyzf600 @valiyzf600 We all know what the current year is. Something being new does not mean it is better and something being old does not mean it is worse. The idea of D-rings not being user friendly is laughable, it takes a few seconds to loop the strap through them. I agree that top helmet manufactures aren't idiots, you'll note that those same manufactures offer D-rings and alternatives. The evidence in this video shows that D-rings are superior, do you have any evidence to the contrary?
@@TimpaNidevo D-rings are not superior, they just have more strength. That does not equate that they are superior. The question is if that strength is needed with the price of a more fiddly setup. It takes 5-7 sec to lock my old helmet with D-rings, maybe a few more if it doesn't feel rightly adjusted from the start, and preferably all of this without gloves. It takes under a second with gloves to do my new one and it's perfect every time, because I only need to adjust it once. The only reason manufacturers offer both versions is because bikers and people in general are creatures of habit and/or regulations that are not updated in some parts of the world.
Interestingly enough any buckle but the double D is common here in Europe. I had to place a spacial order for the double D bucket for my Schuberth C4 Pro. Most of my biker friends give me a strange look when they see me putting on the helmet and fixing it with the double D, but your video proved (again) that I made the right choice and the extra 50 Euros are worth it.
Buy Arai, better helmet and always has double D

🙄 Double D-rings, dude … the strap will break, before they do. Why settle for less?!!
@@kierenmoore3236 Because your neck/jaw will break way sooner than either the strap or locking mechanism ;)
I have the shoei gt air 2 with the metal ratchet. I quite like it I think it is supposed to be easier to undo with gloves on. My Arai RX7 Corsair has the double D as has every other helmet I’ve ever had and it is a great and simple solution
Cool topic, interesting experiment (y) I've always liked the DD better.
As for the protection you guys used. Forget plexi glass. It is rigid and easy to break. Polycarbonate sheets are a bit more expensive but there is a reason they are used as aeroplane windows.
well i love that the most basic is the most strong. also that feeling of strapping up that double d knowing you are rididng cant be beat
Nothing beats a coffee and F9 on a Sunday morning.
Haha I JUST sat outside with a coffee and smoke, delaying my ride, check phone and this comes up, ahhhh good feeling haha
It's midnight here.
Exactly! Coffee on the deck while watching.
This is why they use polycarbonate lenses on motorcycle helmets and not plexiglass...
Same thing and branded. The plexiglass used for this was far too thin, visors (besides trash helmets) are much thicker.
@@MrVTeta Plexiglass is the branded name of acrylic. Polycarbonate is substantially stronger than acrylic.
@@MrVTeta nope. Acrylic is different from polycarbonate. They are forms of polymers but chemically different and different in the process of making them. Polycarbonate is stronger.
@@bananabread7641 are you sure Plexiglas never offered polycarbonate sheets? I could've sworn they sold them in the 80s. 🌈
@@GrimYak You are right, this brand is not sold here and I confused plexiglass with lexan which is polycarbonate. Polycarbonate is indeed stronger. Anyway, even for polycarbonate the sheet they used was far too thin for this experiment.
Hi FortNine and thank you for these awesome videos. I must've watched them many times by now. In one video, I believe Ryan mentioned the motorcycle clutch handle covered with 4 fingers "which is bad for reasons I'll explain in a future video". Can you please make such a video? I can't seem to find one. I'm curious about both front break and clutch covering. Thanks.
you can find videos about it from Brettkacs one of his recent video explains it why. If in not mistaken the title is 2 errors that self taught adv riders do...it does covers the topic for street riding as well.
@@viviansee9989 thanks for replying to me. I will take a look, as I've been following him for a while too. I've been riding long enough to judge for myself which works and which doesn't. The question at hand, was mostly for the "covering" of the clutch handle with 2 fingers as there are numerous ways that this can go bad, especially when doing that in first gear. Thus, four fingers will provide the much needed fines, without accidentally crushing your fingers(it can however work with 2 fingers, in upper gears, but feels redundant). Covering the break leaver with 2 fingers is justified and I have been using it for years. 🙂
@@viviansee9989 I saw the video that you mentioned. He uses 3 fingers(4 wouldn't hurt anything in technique, since the smallest finger doesn't do much of anything) from an ADV riding perspective which is a completely different situation than that of riding on the streets and also because he will have to stand up, on the bike, most of the time when on off-road. His colleague with 2 on the clutch and 1 on the front brake, well... I don't want to see him do an emergency breaking demonstration 🙈 but then again, it's off-road so he should be safe.
@@clue0001 I myself have been using clutch with two fingers with my thumb on the hon which fortnine mentioned in one of his very early videos for city riding techniques. I found it useful as it gives me enough reaction time to play with the clutch when I need it. I don't worry about using two fingers or any pinching when going into first gear as well. I use two fingers for braking as well, that way I don't lose grip for either handle bars. Trust me, I live in city that is always in constant heavy traffic with car having bad driving habits so always having contact with either control allows me have better control over my speed and flexibility to warn people of my presence when I lane filtering which is somewhat allowed in my country.
I found gymkhana and adv techniques are useful to me but not necessarily useful to everyone so that is why we call riding an art, everyone have there own gloves that they fancy.
Fidlock seemed pretty damn strong, too. It couldn't have been far off from being stronger than the straps as well.
@HalibetLector convinced i've seen billet wheels compared to cast in a hydraulic press style crush test, with cast being stronger
Never seen a Fidlock strap before, i am not joking. I didn't even know this connection existed. For me it's D ring anytime. It's simply too good.
For sure! It was roughly 1.5 ft-lb less strong, which is a trade-off I'm willing to make for sure. (Fidlock offers samples of their products. I think I'm going to try to request a couple and try it on one of mine.)
True! As long as it's stressed in the right direction, the aluminum fidlock is nearly as strong as a double D. Though it's a little unnerving how you can knock it open with one finger. ~RF9
Ryan: “a little unnerving how you can knock it open with one finger.”
