It was the bonding that gave out. I believe this was a failed batch

Carbon weakens from impact and you can never know if an impact shattered the binding structure without advanced tools.. aluminium is the way to go for anyone who cannot afford replacing your frame after every accident. I could never ride a carbon frame with confidence if I knew it had taken a hit previously.

Cased the jump badly to be fair

​@HAORGHGH aluminium gets micro cracks as well and they are even harder to to spot because you can't xray it like carbon. Also the welds fuck with the alloy so the properties on every pipe connection are pretty random. Carbon frames tend to take more damage when the frame gets an impact from like a rock or something but in general strength and reliability carbon is way superior. Park pros are gonna tell you the same when it comes to wheels.

that is why i dont understand they give to much credit for carbon for being super stiff against alluminum frame while it cannot handle stress for long

Not entirely accurate. Many are sponsored and are given new bikes. Others just want the latest and greatest. Many companies offer lifetime warranties on carbon now, such as Yeti.

Would’ve happened on a brand new frame, carbon bikes aren’t strong enough

True.

HAHAHAA 😂

Exactly, click baiters leave out that info, isnt condusive of gaining views leaving it in...

Yeah and it broke. Aluminium would propably be good for another 5+ years after selling

​@@alanowa123not necessarily. You have to also remember that this bike was a prototype and not a full production model. It also sounds like the carbon was fine but the bonding failed. No different than if you had a poorly done weld that hung on for a while.

@@RedWingsninetyone you are right, it can be the case of bad bonding

I used to ride downhill bikes in the early days, late 90’s and 2000’s and trust me, there were a lot of broken aluminum frames in those days. Even with T7075 and cast frames. Carbon fibre was pretty much nonexistent in those days even for parts.

Sure did

Yeah super scary

I don't know if I'd fully trust a tube & plug frame

Who is it ?

Carbon is incredibly strong, in fact the tubes were completely intact. Problem with the bonding i believe.

And dude, were they right. Got a new carbon fully XC bike and it's just incredible. Now I'm saving for a carbon Enduro e bike. It's like riding the future.

The yeti did

​@@HuckHope they stop doing so after a few big hits like that 😂 trust. bk's is a few stages in the prototyping back from that yeti too, iteration 1 or 2 compared to like 4 or 5.

You send a lot of 50ft gaps?

I wouldn't let the failure of a prototype frame change your choices. an all-carbon frame made by pivot won't do this, because there's no joint into the headtube - it's all carbon.

@@enzochoi923it doesnt change the fact that their premium bike marketing is suffering now.

Then you can scratch every single brand off your list mate. Every single brand has had frame snaps. A bike that (is not even for sale) went through a full season of DH and 2 hardline weeks would probably be fine for the average rider. I reckon it's done more than its job.

@@luffyluck Its a prototype so I dont care.

Coming from 10 plus years experience in the composite industry specifically Formula 1…Kevlar would be a bad choice of material in those stressed areas… Kevlar is tougher than carbon in certain applications but carbon is a lot stronger than Kevlar is. There likely just needs to be a few extra reinforcement plies in those areas or better bond perpetrations or adhesives used if it’s a bond join that has failed and in some cases supporting plies around the same bond joint. This particular bike had been battered for nearly a whole season and done 2 hardline races as well I believe… not bad for a prototype

It was in fact, not okay 😢

He walked away just fine

I don't think many bikes would have survived that. But it didn't help that he had ridden hardline on it.

Haha true!

Pivot will be fine

Bernard had been riding this one hard for months, including hardline tasmania.

Carbon is very strong but it must be manufactured correctly and maintained well eg torque specs. Both materials have pros and cons but alloy tends to hold up for a little longer before a failure.

Cromoly the best

Sure was

Frame completely separated from the titanium lug.

Yeah, just new adjustable geometry 💀

The pivot is the one that got fucked up

*frame

Mb I just checked yea it’s the frame

Little ?

It may have been the same bike as hardline, which went through some abuse.

sounds like something a carbon bike would say

Dude... everyone knows it.. carbon frames break of a mistake is made. It's just not worth it. Because no one not even pros are perfect .

It was crankworx Rotorua taniwha downhill

Tyler Waite

Any of the good brands only make carbon though 😩

Carbon is fine

The carbon one before the second proves you wrong

Carbon is as strong as aluminium, the failure in this video was the adhesion to the lugs, and frame tolerances. The bike had also been through testing red bull hardline which had some brutal impacts.

Not great to see

But... it wasn't a carbon failure....

yeah pretty bad to have a failure this serious

A 60 foot gap going 40mph isn't that much of a hard landing is it? 😂 think about what you just said

Pretty sure he placed 2nd at Red Bull hardline on that same frame just weeks before. If so that frame had been put through absolute hell already. Not to mention a slack head angle DH frame and a hard case like that right between the head angle would likely crack or damage quite a few bikes. BK is a legend

Crankworks downhill

100% agree, it just looks bad

Nope

Maybe not a prototype ridden by Bernard Kerr for over a year

Yeah don’t think it was a problem with the carbon itself, it was the adhesive they used to bond with the alloy lugs.

After having 2 Gt sts frames I’d never ride carbon again, either the glue fails or the carbon just snaps without warning

​@@BlindingSun_your actual problem was buying GT, they have never been good, they stuck with a marketing gimmick for over a decade and lost out because they essentially scammed the consumer (i drive)

Вообще то и алюминий может сломаться, момент только в том что он прощает ошибки накапливая их а потом может сломаться буквально съехав с бордюра, карбон же ломается сразу и ошибок не прощает, алюминий не гарантирует ничего как и карбон, вспомнить ту же кону))

​@@auf7320Sorry but aluminum breaking off a curb is bullshit. Over exaggerate much??

Just some adjustable geo 😂
