Brilliant solution! 👏👏👏 Cannondale should be liable for such a terrible design and should recall/refund every owner

Very well done. I really appreciate your care for the environment. We need much more of that in the world. Can you please do a video on how you repair broken carbon? It's hard for me to visualize how you actually match the original layup for one, but then how you make it flush and looking new is beyond me. I'd love to see you do the process. Thanks!

GREAT VIDEO AGAin! Happy to report this one only needed 1.25 speed. 1.5 was too fast. Great work chief

Your thoughts on repair are what we need going forward. Actually fixing these companies engineering shortcomings goes beyond - well done m8.

Excellent content as always - Many thanks Raoul 🙏

Very neat and tidy solution, brilliant 🤩

What a fantastic fix. Excellent work

Fantastic and elegant solution to correct the issue with these frames.

I think I'll just avoid frames that route the cables through the stem and into headtube. I need my peace of mind.

I can just imagine Hephaestus saying to Cannondale, Cervelo, and basically every carbon bike manufacturer out there: “And this, kids, is why we need an uncle Raoul thinking logically and giving us sensible fixes for the cr@p we made” 😎 Brilliant video, sir!

Congratulations, great message, recycling and reuse is a powerful way.👏👏👏

Clever solution to repair the head tube!

great job!

This is a brilliant solution to a “less than ideal” design flaw. You are right we need to stop throwing stuff away and get it repaired instead.

Lockdown in Australia, a neverending story. Cheers from Belgium

I have a merida, I paid a fraction of Dale or big s type money, even though it came with full di2 and carbon wheels. It has a stop setup in the head tube, but the stop blocks are big cubes of carbon with a matching seat to mate to. While I bet it's possible to break this arrangement, it going to be a huge impact that does it. Strange that the expensive bikes can't do the simple stuff right.

It’s a crime that the titanium insert isn’t there to begin with! Goes to show a lack of knowledge from the designers thinking up these bikes. I’m all for innovation but the limitations of materials need to be taken into account. Great solution you’ve got there and brilliant to save bikes going to waste over such a small yet important detail. Hopefully if youtubers like yourself keep showing up the big bike companies they’ll up their game and stop making sub par designs!

I wonder how much more sound the older double diamond supersix evo is. One of my fave bike frames.

This is not a repair. This is the next evolution of the bike!

Nice job. I good ethics aswell

Hello Raoul Wonderful solution! Is there any possibility of getting tour titanium plate here in Brazil?

Hi there! Thank you so much for the informative video and thank you to the community for the comments. Would you mind sharing the CAD files of the titanium part for the repair? That would be a great simplification for the repair! Thank you very much!

Any thoughts why they don't just do a one piece bar setup that would route the cables into the fork steerer by the top cap? Seems so much easier to engineer than this void in front of the steerer.

Bicycles are marvelous but the cycling industry is atrocious in many ways. Thank you for saving another bike from landfill.

You are g'damn awesome. I don't (won't) go carbon again unless it be like an old Giant Cadex. Ty.

Is this also a problem with the System six? And will this also fit this model? I have a 2019 Systemsix with the same headtube design and stopper. Haven't had any damage yet but would be interested in proactively stopping the damage 🙂

Does any know if the 2021 rim brake super six evo has the same issue? I’m just about to purchase it.

planing on buying a used 2021 model unknow if this was fixed or not on the 21 model??

Thats awesome, im willing to buy one just for safety! Do you these? Thank you.

BRILLIANT! SOLUTION!!! REAL ENGINEERS FIXING HOODIE ENGINEER DESIGN @1.5x speed always!!!

Brilliant. This just goes to prove that not all people that design carbon bikes are.

Has this been fixed by Cannondale in the 2021 models?

My bike cracked for the second time in that same location and I will continue to ride as it is. It does not look like it is very unsafe as it still has the whole tube supporting the fork pressure but will start slowly and see how it feels.

Where I can get that titanium piece? I’m located in USA.

Hello, can you tell me where to buy this part

My 21' tcr has had 0 issues

That looks like a super solid fix and what Cannondale should have put in the frame in the fist place. Speaking of which, is Cannondale doing anything retroactively about bikes already in the market? Also, would carbon reinforced polymer work for the insert instead of Ti?

Hi there, great fix thanks. I have exactly the same - not quite as bad as your examples but can see crack on outer one side. How do i buy the insert? we use carbon and laminate at work a lot so i'm pretty comfortable in doing it except not sure the resin you mention, Do you provide some instructions for the repair. Failing that there's a local guy who's a wiz at carbon bike frame repairs. Thanks for that

And on the 3rd day him upstairs made Luescher Teknik.

What's the price? In any case now it should fail at the pin. Best to repair, but a carbon frame in a landfill is inconsequential.

what's the cost to 3d print one of those titanium inserts?

We can just casually 3D print a titanium part to fix a bike. This is so cool.

clever hack. any chance you'd ship the part so I can install it pre-emptively on my 2021 super-six?

On 2021 frames they followed same approach as you did, draw back of this - metal stopper on the fork gets snapped. Interesting how they will improve on 2022 model.

Very common problem among these new Cannondale framesets. My buddy had his replaced by Cannondale. I'm glad that when I had the choice, I went with a leftover EVO. #ZeroIssues

Is this the same with the rim brake version of the supersix evo?

Perfect example of what happens when an engineer is presented with a problem. Problem solved, damage repaired, and environmental impact minimized. Nice Job! Now just sell the design to Cannondale. Does this get paid for under a warranty claim?

@Luescher Teknik My Cannondale frame had exactly the same damage and was meanwhile repaired - obviously without your titanium part, though. Would you ship the titanium part here to Germany so I could have it installed by a local carbon specialist (who did the repair on my frame)?

Any idea why this issue is present on the rim brake version too? There was no need for them to put in a hydraulic hose defence mechanism...

Where can we purchase this ti fix please ? My SS Hi-Mod has no damage so far but I have accidentally turned the bars full lock and felt the pin contact - so would like thus repair to my unmanaged frame ?

What a great solution. Is there any chance of getting this titanium insert shipped to the UK? I have an excellent local shop that does carbon repairs who would be willing to insert this for me. Already had one frame written off due to cracking in the head tube, and I'd like to do some preemptive work on my replacement frame. Thanks again for a great video!!

Great video Shouldn’t the manufacturer be retro-fitting these, or using local specialists? How would 6000 Al or stainless compare in machining, corrosion, cost, durability?

Brilliant fix! Can this be purchased and installed on a non broken frame to prevent it from happening? I am very interested in getting my hands on one of these!

Looks like a 3d part fabricated by Bastion?

won't the metal strengthening of the head tube now break the pin? I think I read something along those lines, perhaps was juts someone expressing a concern

Теперь осталось , получить патент.... и сорвать джекпот с Cannondale👍!!!

Is there a befit in limmiting the steering rotation? I wonder why they do this on high end bikes.

Did Cannondale adopted a solution like yours on the recent models?

Man the more I see these videos about these carbon bike issues I'll stick to my aluminum frames

Why do the less severe examples need repair? Is it your contention that this would weaken the headtube and cause further delamination without further stress? Thanks for considering this serious question.

Do you sell these inserts?

clever. but what are your thoughts on the utility of hairdressers?

Not defending Cannondale , but under what circumstances would anyone turn the steer tube that far? Is this just from passive impacts of handlebar rotation when lifting up the bike?

I am wondering, are Cannondale replacing these frames and repairs you make are just for customers who don't want to bother through going with warranty service?

Hi Mate, I have the same issues 🤣 would like to get a quote to get this fix from you please.

Bikes should be simple. We already have complex cars.

Hello Raoul, i hope you are fine in Australia. What is the solution for european SuperSix owners to fix that ?

Does any one know if the issue is present in the Super Six Evo SE/CX model?

This is pretty hilarious, and sad. Do these designers actually test the products they make or have any practical experience? because this issue seems pretty obvious.

I have one I'd love to have you repair. However I'm in the U.S. It would be great if you were to license a trustworthy carbon repair shop in the U.S. to do the repair using your part. It's a lot more environmentally friendly shipping your part across the seas than shipping all those fractured Cannondales.

Hi every one ! That’s the same thing In my bike and take off a big chunk in my folk and crack the paint in the frame to

It must have been designed by the guys who also designed the cervelo S5

apart from the energy wasted to build the bike, which is not negligible, the carbon frame is actually a carbon sink, as that carbon will not be released any time soon

Cannondale are replacing frames under warranty. If a dealer doesn't do it go straight to Cannondale.

Why The hell Cannondale did NOT evaluate that risk in the first place and come up with a solution.......beats me! Lets Hope PON HOLDING will do a better job now they've bought DOREL SPORTS.

I just bought the supersix evo.. it was around 4700... I only used it once for a short ride. It's a 2021 model.. would this model have the metal plate you mentioned?

Metal pins on carbon..what could possibly go wrong!

Content audio loudness if this video is -15.4dB

I can also see a large area of half depth/ unsupported section for the outer bearing race! More poor design. This is one of the most highly stressed areas on the frame! Shocking design.

I'm no genius, but a metal stop pin slamming into carbon will obviously damage the carbon. The harder material will win every time. The fix is only temporary imo too. The harder material will eventually destroy the weaker one. So maybe the TI fix breaks the stop pin and you eventually shear your internally routed cables. This is a horrible design, Cannondale engineers must be 5 years old to let this out to the public.

It seems many of the manufacturers put out poor quality, if not out right dangerous carbon bikes. Internal routing thru the head tube for hydraulic cables, is totally stupid as you can't even see the wear taking place

Unfortunately it seems a few class action lawsuits are needed before the cycling industry takes product safety and quality seriously.

Canondale have to take them all cus is a lot of bikes like that my model is the 2021 and they no sed nothing about it they ignore me and I pay 3500 for my bike

The same engineering approach that sees aero as the most important of design goals caused the fault in this model, as well as the Specialized fork failure recall clustercoitus that Raoul has just reviewed. Perhaps frames should be designed for structural integrity (& rider safety) first & foremost, & saving a handful of watts with shiny surfaces much lower down the scale? Anybody? Bueller? Bueller?

The level of incompetence in the bike industry is so ridicules... but as long as they don't run out of idiotos who pay 10k for literally every shit I guess there is no need to change the business model

Thats bad cannondale quality control is horrible with Cannondale and there warranty is garbage

I grew up about 25 miles from the Bedford PA factory. It is sad that they made a world class product in the USA and moved it to China. It is sad that they now make a crap product.

Oh! Just hush about unsustainability!! There is plenty of room on our earth for landfills. In ten years we'll all look back and say " Man! Cannond.... speciali.... and Cerve.... made crap bikes! I'm glad I threw mine in the trash and got an X, Y or Z.

To me this just reeks of inexperienced designers not having anyone around to do design reviews. Is it a case of all the good engineers end up working in aerospace and F1 and the leftovers end up working on bikes? (Probably getting paid next to nothing while the marketing guys take home a packet by the way)

What idiot engineer designed that? A metal pin bumping up against a carbon fibre surface is only going to end one way. Nice job Cannondale.

Just wretched engineering and design from Cannondale. And this is from an non engineer.

Ladies and gentlemen, step up step up. Who will be the first manufacturer to kill a rider through abysmal engineering? Come on manufacturer's don't be shy, will it be Cannondale, Specialized or will it be Cervelo, Canyon to take the mantle through mediocracy, mindlessness and the race to the "bottom" engineering. Come on we're aiming high to aim low. What's that you say, handlebars, seatposts and frame junctions? Or can we save a bit of time through catastrophic steerer failure whilst braking and face plant into the tarmac breaking your jaw, smashing every single one of your front teeth as they eject straight through your mouth below your lip, before lubricating the tarmac with your brains from your broken skull. Roll up roll up. Which manufacturer, which failure first. Maybe a failed brake hose on a Specialized, WHO WILL BE FIRST? Who be the first rider to buy it? Stayed tuned with these manufacturer's as your friend, you won't need enemy's. The grim reaper or is that rider is on they're way. Bet your resale on a SL7 is looking grand. What a total dogs hind leg
