  • In Australia all the new one uses a different sort

  • Wooow!!

  • 👍💥🔥

  • I've never seen a non 1997 type helmet in years over here

  • damn right! thanks roman empire!!!

  • “The ‘double-D’ is safest.” Well, only if real-world situations involving crashes are represented by this test.

  • It's odd that I never see two D rings on bike helmets, and yet they're on ever motorcycle helmet I've had.

  • I have been through 3 Givi X.08 Flip lids over the past 5 ish years and they all had the rachet strap. My HJC IS-MAX was also the same. The last helmet I had with a DD was a HJC flip lid but i do not recall the model back in 2007 ish. Never had either kind fail or break on me mind but I have not had a major crash.... yet.

  • 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 really like these videos you provide great entertainment with worth wile facts. and you don't waist time doing all this. Thank you once again.

  • *Strap flies through the pane of plexiglass* And that''s why we use polycarbonate and its much better impact resistance.

  • Rider hates double d buckles for its inconvinience in wearing, but thats what side mirrors are used for.

  • The the twist weight on your ratchet is different than the weight on the strap..

    • 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.

  • Worst testing method ever. What is the ratio of the force applied vs given to the strap... all those tests are meaningless

  • 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

  • Meanwhile, Ruroc using fidlock in their cool looking but shitty helmets.

  • kudos to the guy who sold me my first motorcyclehelmet, telling me the "double D" was the choice of moto gp drivers and is the newest kind of closing mechanism... first part was right, but "newest kind"? that makes me feel stupid now

  • Also used on climbing harnesses, which have exacting safety requirements, for the same reason.

    • You really don't want quick-release climbing harnesses... Carabiners maybe. But not the actual set of straps I am hanging from.

  • Never seen any shoei or arai using other than DD.

    • 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.

  • Cuz it works lol

  • SHOEI GT Air 2 has a metal ratchet (snowboard boot) style chin strap. can you test one of these?

  • Don't try and reinvent the Big Mac... just don't.

  • I actually wonder if a part of the safety is the consistency with which these could be made. Manufacturing tolerances are less likely to cause problems, the simpler the device, right?

    • Of all the wild machines I've built, this piece of plywood was probably the most dangerous. 10/10 would ride again. ~RF9

  • Started working in my garage at 4:30 this morning. Watching videos, some old some newer. Easier to work on this 1990 GSXR 1100 when you have company.😁

  • C'est de la merde ses D rings, impossible de les mettre avec des gants.

  • We stoped using this D rings crap in Europe about 50 years ago...I don't miss it.

  • I’m sure in motogp they are using double d and another buckle so belt and braces

  • Now I understand why my race helmet hasn't got any cool zip lock connection.

  • … but ruroc

  • I was wondering that while at a bike shop two month ago.

  • Nope. Don't care. I'll never buy a helmet with d rings again. I can't stand them. Using them with thick gloves in the winter, or being stuck in a hot ass helmet for that extra time undoing the d rings in the 119 degree summer, are both things i will never put up with again.

  • Ryan: A pair of Double D's can save lives! Manufacturers: what?? Me: oh yeah!

  • you should have had the slowmoguys with you when recording this, it would be interesting seeing the snaps break

  • 3:40 did that break due to being on the curved block? Does it break if straight on the side? Hard block vs squishy neck?

  • another darwinian bennie: if you can't quickly master the art of threading the DD, probably not gonna be too great at all else required once you actually mount the rig.

  • Who in their right mind would give such a fantastic, life saving, and informative video, all those thumbs down?...... Unbelievable.... Thanks Ryan for your outstanding videos, Take care and keep safe.

  • i can't belive the production on your videos, it's insane

  • RUROC MAGNETIC FITLOCK😅😂

    • Will always look back fondly on that first week accomplishment of securing the Double D with gloves on. Wouldn’t have it any other way :)

  • I have a Ratchet on my helmet and ride a 125 Suzuki van van on a CBT.. When I pass my full licence and get a bigger bike the DD is a no brainer

    • 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.

  • All hail the Fidlock Buckle!!! Etsy store even has them for sale as a retrofit kit. Excellent Video on buckle tech, as an everyday rider I'll take the one handed magnetic option.

  • Love fidlock helmets myself and to be fair much more confident using it after watching this. I dont think it was too bad in comparison to the others.

    • nowine.info/loft/pomEsoaddrWRoII/video Would love to see the Echo Quick release buckle tested this way. It claims to exceed SNELL, DOT & US DOJ safety standards

  • Well, its good im a 4 sec double d user Wait That came out wrong

  • They are a pain to open/close with thicker gloves.

  • Where are u from? Surrounding looks beautiful

  • DICK CLIP AHAHAHAHAHAHHA

  • I've been using the Echo quick-release buckle for many years. It has a metal-on-metal connection, although the outer shell is plastic. I'm interested in knowing how these compare in your test.

  • Now make straps with some material that wont even snap

    • nowine.info/loft/pomEsoaddrWRoII/video 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.

  • Am Ami and still say that D rings are annoying and cumbersome. I won't ever buy a helmet again that doesn't use the far superior ratchet system. You only have to adjust the straps once so long as you don't gain or lose a ton of weight in your face. If I'm broke I'll run a LS2, if I got money, Schuberth it is. I don't dispute that a D ring may technically resist more force, but it's irrelevant. You're not going to see enough force to you're head to break a rachet that doesn't have some sort of material or manufacturer defect without it being a fatal crash anyway. The slight "when the stars align* theoretical advantage offered by the D ring is a silly thing to be worried about when you're already engaged in an inherently dangerous task (motorcycling) and both methods pass all current helmet certifications.

  • I hate dinking with Double Ds everytime I ride (wait, what?!) but if it'll save my life I guess I'll have too

    • “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…

  • Cool house. 1:40

    • Got the ratchet thingy on my Shark helmet and I love, how I can just do it up or open it with my gloves on. DD on previous helmet drove me insane!

  • Totally agree. My latest shoei GT air-2 has some kind of ratchet buckle and sometimes I don't connect it properly (easy to insert alongside the buckle instead of in it) and you don't realise until you're riding and feel the strap flop around. Double D is straightforward and easy - why change it?

    • “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…

  • Thanks, almost did the switch. Double D's get caught up in my beard when i try to take them off, but small price to pay

    • 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! 😁

  • To be honest, it seems to me that in this type of jack the dependence between lifting force and turning torque is not linear. Maybe, you could even break different types of buckles with equal torque, but with different lifting forces. Am I not right?

  • The first skill? I've never learned this skill, nor did I need it in 10 years

  • Wrong plastic to use as a shield since it shattered like that, but it was still very entertaining =D I love these safety related test videos!

  • Please review the Royal Enfield Himalyan

  • Pretty sure I can produce enough force with my bicycle to break the first one. Garbage.

  • Wow

  • dd is also more reliable and do not wear out as fast. plus i have had in crashes the non dd straps get stuck and have to be cut. not the best thing when you are trying to remove pressure on the air way without removing or moving the helmet. you should have also tested them at what point to they stop functioning and being able to be opened.

  • Plexiglass is a brand of Acrylic which is brittle and fragile as you saw in your experiments. You should be using Polycarbonate for your protective screen

  • Used to have a perfect Shoei Jcruz with the ancient buckle. But alas the new Shoei JCruz comes with annoying heavy ratchet. Constantly smudged drop down sun shield, and crap ventilation. But hey we get shitty SENA mounting which makes me mount my Cardo further back…dumb bastards ruined a perfect helmet.

  • fortnite

  • it is a shame that Fortnine does not do weekly videos....

  • 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!

  • Funny, I'm from Holland, i've tried quite a few helmets on and,.. I didn't even know the D ring was still used. I thought all modern helmets had switched to the 'ratcheting' type. I don't think I've seen a single D ring in the stores I've been to.

  • Dislike and unsubscribe? What do I win 🤨

  • I does look like you guys didn't do the ratchet strap up fully and just had it sitting on the last notch. I also think you miss the benefit of simplicity in the connections, I have seen many many inexperienced people do up double DD's the wrong way and have them be useless. With some of the other methods it's very obvious when it's not connected.

  • But is my helmet manufacturer using materials and designs that are in spec for buckles?

    • 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.

  • I hate putting that thing on I hate it rubbing in my neck and the time it takes so much time to put on and take off

  • Not only have you Been filling my head with classy knowledge. You may save my life. Bro I think I love you.

  • Whoa… good thing I don’t wear a helmet.

    • 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.

  • for sailboat sunroofs there is another option that combines most advantages of the double rings and the more modern shutting mechanisms they are steplessly adjustable, and have to be adjusted when used every time, just like the rings, but can be quickly opened up again, as the strap is clamped onto the ring by a metal plate pushed down with a spring

  • thank you guys for your work, simply perfect and informative as always

    • Got the ratchet thingy on my Shark helmet and I love, how I can just do it up or open it with my gloves on. DD on previous helmet drove me insane!

  • Super enlightening. Thanks a lot

  • I was so curious about my new MX-9 Adventure MIPS helmet that comes in Double-D lock, I didn’t know what to use and wonder why it is this type because many of helmet use other type of strap lock. Now I know Thanks!!!!

  • How the hell does this channel only have 1M subs? I'd figure he would have much more, either way good stuff.

    • “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…

  • 4:44 So it failed not at the connection but at the buckle ring. If the D Rings where out of aluminium it would fail the same or am I missing something. This has nothing to do with the forms but with the materials used.

  • Man I had to shut the volume off, the background music sucked so bad! And my magnetic clasped bicycle & ski helmets ars always adjusted properly. Thankfully my parents were smart & they imparted some intelligence to me. (70 yrs old now)

    • nowine.info/loft/pomEsoaddrWRoII/video Got the ratchet thingy on my Shark helmet and I love, how I can just do it up or open it with my gloves on. DD on previous helmet drove me insane!

  • I just purchased an expensive helmet with quick release ratchet system will be returning tomorrow for d ring style, thank you for your continued information concerning safety.

  • Were those readings taken straight from the torque wrench, or did you account for the angle of the jack? The only time that the reading of the torque wrench represents the pressure on the strap is when the the angled parts of the jack are at 45°. Steeper than that and the torque meter will read lower; shallower than than that and it will read higher. The only way you can compare those numbers is if they all broke when the jack was at the same angle or if you adjusted the results based on the angle of the jack.

  • One cannot simply reinvent the Double D-ring.

  • My old helmet was a quick release. I bought an expensive AGV helmet and was surprised that it had d rings. At first i thought it was more inconvenient to put on and off. Also paying more for cheaper straps. Then i saw this video then im now convinced that my expensive italian helmet was safer afterall. Thank you for this informative video!

  • Great video. If you are looking for safety while filming best change to a polycarbonate screen and stop with the brittle acrylic (Plexi)

  • Ironically disliking and unsubscribing is exactly what I've done

    • 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' ve seen the cheapest helmets use double D rings, and more expensive models use the ratchet...which is easier to use but you then pay more for a less safe product..... Reverse psychology perhaps

  • still prefer ratchets and fidlocks tho.

    • Will always look back fondly on that first week accomplishment of securing the Double D with gloves on. Wouldn’t have it any other way :)

  • I lost it at the end!

  • what is this shit? only the d rings were made out of metal and the others were plastic? this british fish and chips rapscalion is really grinding my spam with this clearly biased testing. he probably prefers soccer over football too, just vomited inside my mouth.

  • That test looked more dangerous the actual motercycle riding 😳

  • Probably best marketing in the world 😉

  • Where could I buy those double-Ds to fit my helmet?

  • to be honest, even if the info provided is excellent, with a type of damage serious enough to wrench the helmet out of my head, I'd be too dead to care if my buckle fails or not.

    • 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.

  • God d- rings on my agv and hated it for the reason it was fiddly when I can’t see it, but I’ll take that after seeing it’s actually going to not break 😂

  • glad to see the camera taking proper precautions

  • I run the ratchet quick release on my mx helmet😁🇺🇲

  • Disliked and unsubscribed. >:(

  • do you actually measure lift force, or calculate it based on the torque applied? (force is going to depend on the height of the jack at any given time, based on the angles of the "arms" to convert the lateral "squeezing" from the screw into upwards force). I'm also not so sure the strap failure is so conclusive. the strap is *part* of the buckle with the D ring, and it looks like the D ring basically sliced through the webbing (and you won't get slicing with the other buckles). still a very interesting series of test though

  • Very good, you moose hugger ;-)

  • Rip RUROC hahahaha

  • Would be nice to see buckles break in a slow mo. And ... lats be honest ... it's way more easy to unbuckle with "alternative" buckles than D-rings...

    • nowine.info/loft/a21njnKTadpxfWE/video “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…

    • I've had helmets with every fastener shown here other than the fancy german magnetic one. I can undo my D ring helmet with one hand in all of my gloves (including the fumbly winter ones) and it might take one second more than a clip. It''s not difficult at all, once you know how.
