- Horrible Crash caused by frame failure at Crankworx Rotorua.
There's never a good place for this to happen,but better being there than the container drop at Hardline!!
Thankfully BK seems to have escaped relatively unhurt,he's made of tough stuff that fella💪 - Krátké a kreslené filmy
Pivot living up to it's name, just in the wrong place
"No one wants to see that." Thank you for not saying, "Here's another angle," Rob!
Luckily it didn't happen at Hardline!
i thought the same !
If it's the same frame then maybe it did
He already crash at hardline front wheel bend
“If we made this frame it would cost 20k” Pivot CEO 😑
Did he really say that? 😂
Can you explain the context a little more for me please?
In fairness, I doubt there's a single customer of pivot who rides at the level bk does so you're probably not gonna break it 😂😂
Maybe he was talking about the hospital bill.
it costs that much because it is in such small numbers
I hope he recovers quickly. He is a great lad.
“Worst ‘case’ scenario” 😅 Rob you legend!!!
thanks for the replay. Absolutely devastating to see this happen to a seasoned rider like Bernard.
Damm those in the background laughing 👎👎👎👎👎
Yep… pretty disgusting
I find it hilarious
@@kingflynxi9420ya prick.
@@kingflynxi9420A punk would. Hope it never happens to you
i thought the same but on a re-watch I think thier fast reaction was "oh sht!" then the camera cut to them and it caught them off guard
The drone pilot did an amazing job on that. I didn't even see it at first!
Poor ole Bernie.. Pivot need to do some serious investigations on that frame ..
It’s a proto sooo….yea, it’s in the works obviously.
Tbh not sure if any frame would survive a case like that
@@danielensign8817 The one guy earlier did the same jump and undershot it and his bike just bounced like its supposed to.
I think someone f'd up on the carbon to the lug. maybe pressed it wrong and got a fracture into the carbon.
@@zekeyeager1458 Not any more! One-piece carbon layup for entire frame is always going to be stronger than multiple sections epoxied together with alu hardware. Looked awesome though.
What a nightmare. Just imagine your bike separating underneath you…
Imagine being multimillion dollar company that can’t make a bike decent enough for your own riders
Hope your ok bk 💪💪
I think something was wrong with the bike after the first steep section, it was in his body language he was frustrated. You can see in his times he was losing time at all the check points. He had to pull so hard to try for that triple and then the headtube exploded. He was committed like the professional he is. Sorry BK for the bad crash. Now you and Jenna can be broken together. Get well dude!
Gross
that wasn't the problem, the problem was the landing, the design of moderns bike have 1 mayor flaw, if you put at 0.25x the video you see that he doesnt land the 2 wheels on the front of the ramp, at the hill he land the front wheel passing the top, and the back wheel behind the top, when you land at that exact position, the front part of the bike and the back moves to 2 differents places, snapping the frame, you can bring a lot of bikes, at the same speed and the same place and a lot of them are gonna break.
The speed was insane at this moment, I hope he is not so hurt
They could glue the tubes in as normal then wrap the 'joint' with uni-directional to eliminate this issue....I feel for ya mate...those sort of crashes are the worst...I once built a new set of wheels, flat out on the fastest part of our DH and for no reason went straight over the bars just like in that clip....luckily I was alright and went to check the bike out...almost all of the spokes heads had sheered off at the rim...just couldn't believe it...next week and the bike shop get a recall on a batch of 'bad spokes' from DT....
Hope he's okay. He did seem to hit his head and arms/wrists pretty bad. That sucks.
awww the new pivot frame material, toilet paper and glue!
These are hard times for manufacturing and factories i guess
Worse... I think it might be carbon!
I was just reading about their new lugged dh bike. I guess it's back to the lab for Pivot.
Dude in the green hoodie needs to get checked for laughing like that on another man’s downfall
The girls around him too :\
@@bmar916 I know even sacha earnest was laughing and then she tried to hide her face😠
they laughed at the fact the got filmed
@@ignaciosevil2157 how would they know
He's not as liked on the circuit as let on. Not my opinion, just what I hear friends on the WC circuit say 🤷🏻♂️
Hopefully these lug/tube designs factor in the stress concentrated at the interface due to the change in stiffness from the lug to the tube. Ideally, changes in stiffness should be feathered out to reduce stress concentrations.
The glue gave way
the frame didnt snap......... epoxy let go.
The problem is that aluminium and carbon don't get together really good in a gluing situation due to oxidation. If one wanted a glued assembly to hold is to do it with titanium which is at the opposite side of the galvanic spectrum to carbon and will secure a good bond. Atherton cough cough
@@MrSupermugen interesting, I didn't realize it was the epoxy
@@SuspensionBikesMusic I'm not claiming it's ideal, but there are ways to reduce the corrosion potential. Some are: anodizing, bond priming, ply(s) of glass around the tube. It'll be interesting to see if they stick with aluminum in production.
Savage, looks like a wrist, get well soon 🤞
That looks really bad. Unbelievable the bike just folded like that.
it didnt fold at all.
RIP Stonkz Pivot
Is he OK? Anyone heard?
That’s why it’s still the “prototype” Phoenix frame….like being a test pilot I guess so at least Pivot will get failure data from this to use in the design… I think we get too used to things never failing, if it’s a prototype these things are more likely. Hope BK recovers soon 👍
I know at least two people on pivot that snapped there production frames.
😂 “Hi my name is SL7 and I approve this crash”
It didnt happen in Hardline. But in a softer race?
Looks like he pushed that bonded frame past it's limits... hope he's okay.
I guess they're not gonna use lugs again...
That will cause ptsd. How could you trust it in the future races?
No way I would set foot on a Pivot again after that. Time for a new sponsor, even though BK said he's staying with them.
@@kjsinsaino You take risks anytime you ride, drive, fly etc a prototype design. The epoxy issue may kill this frame design, but BK new the risks of pushing it to the limits. Guess what, he found them.
pivotgate!
Obviously the bike has taken some big hits, but I'm guessing its failure was partly due to the way its made, where the lugs stop and the carbon tube start is a very high stress area, the lugs need to have a chamfered edge in the case of carbon probably a more extreme chamfer for use with carbon especially as their yokes/lugs are aluminium (very little flex) The Atherton's bike's are Titanium yokes/lugs Titanium has nice flex to it and the Atherton's frames do have a nice big chamfer where they meet the carbon tubes.
Pivot might have a chamfer also not see the frame close up so I'm not sure. Will be interesting to see what is said about this. That could of been very serious
Glue gave way
I understand that the epoxy failed, but that doesn't invalidate your point. Big change in stiffness going from the lugs to the tubes.
@@PinkyFingerPedalStrike so, not gonna defende the manufacturing but the rider this ones has a lot of blame, he clearly was short of speed and instead of land passing the hill, the front wheel pass and the rear stays behind the top, that creates a point where the frame goes to 2 directions when it slides on the landing, obviously, breaking
Bernard said the frame didn't snap. Curious to know exactly what gave out/broke.
Almost looks like the headset
Shit!🫣 hope your good BK🤞🏻
Hope Bernards ok 😮but i gotta say when i first saw that frame ...i bet it broke on the one of the lugs .
Looks like it snapped at the Lug,Head tube area ?
Yeah that is were the old GT STS used to snap.
Nothing snapped, hence no loud noise, the lug popped off the parallel tubes, very weak design, not how lugs are normally used having a large angle between the tubes.
@@digbysirchickentf2315 lugs have been around since the invention of the bicycle...well kind of . On old steel road bikes lugs were commonly used ...how were those lugs used ? Brazed , welded etc ?
@@daveandmerlin The point is that the tubes which attach to the lug are inline (0 degrees), that is very different from a traditional lug which has around 45 degrees angle between the tubes, so they cant 'fall out'.
the lugs and tubes are glued together on this prototype Pivot bike. Besides Atherton bikes I don't think anyone is doing bike designs this way. I would prefer welded joints even if they can come apart as well.
What were the group of people laughing at?
One of them had farted at the exact moment Kerr hit the ground, almost like they'd done it for comic effect
You say it is better here than hardline, and I agree, but also makes you wonder how much fatigue a frame can take? Was it the same frame? it's a reasonable assumption.
Pretty sure its a prototype with set joints that the frame sits into. Don't think it was a welded joint
Defo mate,those lugs and bonded tubes scared me when i first saw them on the Atherton bikes but theirs seemed to have stood up to the test.
I bet the Pivot team are crapping themselves bigtime!!😱
its the same frame that bk had since early last year. its done a full season of dh, a full season of crankworks, 1 and a half hardlines, untold laps around dyfi. plus all the other stuff that bk has put it through(off season) bk's bike has seen more action than all the other pivot prototypes too.
just remember that it was the first prototype from pivot, and pivot signed bk up because he has a way of finding faults in bikes...well hes found a big ole fault here...
pivot will sort it once they get the frame back to hq..
@@mej6519 would be interesting to see where exactly it broke.
@@elliotwilliams7421 just hope pivot factory will be open and transparent about this.
These are not production bikes, you can't throw 25 grand at pivot and ride off into the sunset on one of these,
They are pure prototypes in the true sense of the word.
Same frame since hardline?
dude, that is bad for pivot advertisement !!! hope BK is ok.
These are prototype bikes and this can happen to any brand. These riders ride hard because they have to, and that will obviously stress any components they use. It's sad to see him go down like that, but it is also part of it all that everyone in that circus know when they sign up for it. He's a fighter so he'll claw his way back up again.
I was looking at the video more closely, I hope BK didn't break his wrist. looks like it on the video. @@a8f235
@@Peak_Mid where is it touted that carbon and lugs is "cutting edge new tech"? It's been used for 20+ years.
Was that a KTM frame? they all break like that.
Case ace. Real bad landing...
!
They use steel/aluminum dropouts and BB shells, why the hell not reinforce the headtube with Aluminum under the carbon on a jump bike. SMH this was bound to eventually happen.
What exact part of the frame snapped?
none because it didnt snap...
The headtube junction or “lug” has carbon tubes pressed into with adhesive and they pulled out. Pretty crap design to save negligible grams? Cuz it definitely isn’t strong lol
Real proof that bikes these days doesn't worth there price tag
how bad was BK hurt
To be fair to pivot Bernard landed hard on the jump where the jump wedged the bike between the front and back wheel, I’ve seen frames snap like this a 100 times, it’s a headtube snapper and Bernard probably knew as he was landing that his bike may protest?. Land like that on a jump and the leverage forces are insane, I don’t think many frames would stand up to that? Bit of pilot error maybe in my opinion?
Carbon frame?
At least it pivoted
Hardline Frame?
Won't be making that mistake again. I was thinking there was something off about his riding at the top of the course. Like he couldn't quite put the bike where he wanted and then this happened. Definitely already compromised.
Crazy!
Terrible look for Pivot!
'worst CASE scenario' rob warner.
‘Worst case scenario’
Was it a carbon frame
Carbon tubing but joined together with alu lugs and hardware.
Speedy recovery get back on 2 wheels soon
Ouch!!
To be fair, he did case the jump. The rear wheel didnt clear the lip so basically the force pulled the frame apart.
It's called foreseen misuse and as a manufacturer you should take this into account when designing the frame.
Grab an old Foes, MC, intense or dare
Carbon. No thanks, I move back to aluminum everything.
Worst CASE scenario. Sucks to suck!
frames crack often this has happend in the past to other none proto frames. The fame didnt even snap just the adhesive between the lugs and carbon tubes failed due to i failed treatment to the alloy lugs that allows to the adhesive to bind properly.
Clearly there is a pending warranty claim with his local bikeshop.
This could never happens, the frame is the only part that could never be broken!
Honestly it’s a toss up blaming anyone is not gunna do any good I’d say the level of riding & equipment is pushing the limits & if you try and triple & case you cannot expect that every now & then a frame is gunna snap. It’s just the reality. 🙌
💕Wow💜💜💛💛💛💜
Wadduh jatuh keras sekali
Good advert for pivot….
it's a prototype bike come on
That'll be $5000 plus tip for a crash replacement
@@alexandredelaunay6306 Does that make it ok though? No bike should snap, proto or not.
@@hangnrashr Yes but it's not a big deal. With a case like that and after he rides redbull hardline with this same proto bike it's ok
@@alexandredelaunay6306 I might not be picking you up incorrectly here.... So your saying every bike that rode Hardline a couple weeks ago should be scrapped? Just trying to understand..
Isn't this basically just a copy of the old GT thermoplastic frames from the 90"s?
Made “IN HOUSE” at their China location 😐
Not a good look for Pivot
Nothing sells bikes like broken frames, lol.
Great advert for Pivot
PR Firm to the rescue to convince the brain dead that their engineers know what they are doing, despite the worst possible failure ever.
This also tells you about quality control in large companies especially now that they have grown too much
Doesn't say anything about quality control in large companies when this is a prototype bike, made in small quantity
@@harrisonedwards1583 let's put it this way, if this happened on a formula 1 or moto gp it would be on every newspaper around the globe. You do not understand how much of a public Fup this is.
I know what you mean. Why ? This summer I bought a Canyon Torque Mullet DH; rode it a few days in Les Gets before a mechanic in Chatel tells me my fork isn't even mounted properly. I'm 26, riding since I'm 14, this was my first modern DH since 2012. I'm kind of on a semi pro level on the bike but not on the finances xp I have tons of stories about bikes being sold and shipped fast despite having component's compability issues, worst being the frame design in this case. I was really angry on the bike industry this year. I don't know If i'm paranoid at this point but I sometimes feel like it doesn't seem profitable for them to produce solid and reliable bikes, they gotta make "appealing" bikes that always look to perform better than the previous one and that you'll feel the urge to replace when multiple of the bad consumings parts will break. New bikes are incredible though, they've maybe just became too good ..
@@eltonio5833 there are many boutique companies that make wonderful bikes and you can contact the owner. They don't do much marketing but quality is top. Design wise it is just a bunch of bs what big firms market. Canyon at least keeps prices low and yes lots of quality issues. Again if these were registered vehicles or motor vehicles they would be more careful. Ah remember rockshox assembling the internals wrong? A few years back we had to open fix and reassemble
He mustve seen an 18 year old on the ground
Too many hardline jumps
Not a good look for pivot... there old frame looked killer, and shame to the people laughing
That was narly. Like totally radical bra.
Bring back the 26inch aluminium frame, it's still a weapon not to be forgotten,
Sorry about the crash bk
Hope you are okay,and get your self a glory DH
29 and mullet are greats but yes alloy is more solid ! carbon is frightening me
Yup. I’m still on a Stevie Wilson. Devinci. Lifetime warranty.
@@user-ht8cx7vm4w hard to tell exactly where is snapped but it is entirely possible that it snapped at the alloy lug. I'm not a massive fan of carbon for different reason but the carbon is weaker narrative is insane. Bikes are going to break no matter what you material you make them out of if you are pushing limits of the engineering, especially on prototyoe frames.
@@jameswillemsen2609 yeah carbon can take more abuse than alloy, but if carbon fails it's just sudden. You can't really see wear on carbon most of the time whereas with alloy you can see micro tears in high stress areas and in my experience alloy would rather bend than just snap off.
Worst case scenario 😏
Not sure what was soo funny to those young spectators.
Why would people be laughing?
Doubt a pro is riding an old or abused frame. Landing wasn’t the smoothest but hard to imagine frame snapping on that jump/landing.
Ich denke mal das war ein Carbon oder noch schlimmer ein Magnesium Rahmen wir haben vor 20 Jahren einmal Magnesium Steigbügel im Rennsport benutzt die sind fast alle gebrochen 😩👎
He went too big!
Call the laywer. This was a really bad case.
But it's Bernard. He'll just say " Ouch" and get up again
Wow thats not fun at all!
Correct me if I'm wrong, but if that frame is made of carbon fiber, then it's a pretty dumb idea in a gravity bike, just as the carbon handlebars. Go aluminum and it'll never snap that way.
No correction needed, you are right.Aluminum fails but not like that.
It was a prototype bike with a mix of carbon and aluminum. The break occurred where the two different materials were bonded. The carbon did not break.
too light frame for rider of that level
That's the thing with Carbon Fibre! You might not know it's cracked until your face eats the dirt!
Actually it was CF/Aluminium frame, and it gave up at the weakest point in the system - Bonding between materials
well noones buying that bike ....
pivot needa pivot to a different design💀
i'd not wanna ride bicycles after that bs
I would never put an untested frame in the hands of a world cup racer. That failure is bad, it was not an out of boundaries situation it landed short but it wasn't a crazy impact.
Who said it was 'untested'
@@tyrellcobb4665 me, it is unlikely a prototype has gone through ISO or ASTM lab testing, if it did and it passed it must be a manufacturing defect, which means nobody checked the frame. Unless the whole project design was done wrong from the beginning but I doubt
Pivotal moment in the race…
Needs a Pivot... 😊
I find it unacceptable that a frame would snap like that. It would be embarrassing if they weren’t so incredibly expensive, but it’s absolutely infuriating as it is. If I were him I’d switch sponsors immediately
Totally agree, would never trust them again!
1)Carbon didn't snap. 2)epoxy let go 3)Completely Prototype bike 4)BK knew the risks and is committed as a test pilot for Pivot. 5)Innumerable pro-level DH laps on the hardest tracks over the last year.
What are you worried about, you can't even buy this design from Pivot. Gonna get a lot more R&D, of they don't abandon the design altogether.
This is why I jump dirt bikes, not bicycles.
