Checkout this video where I cut open a Canyon frame - czcams.com/video/pYBY78-zs7Q/video.html
These are my favorite CZcams videos. Cutting different carbon fiber frames open and analyzing them is a superb idea.
Glad you like them! 👍🏼
Hi Jourdain, If you have access to a borescope run one through the frame prior to cutting to observe any discrepancies in layup.
Good suggestion! It's worth a check before I cause any potential damage 👍🏼
@@JourdainColemanвы мастер по корбону?
Many years ago I owned an early Italian, Alan carbon bike, with Alu parts/corners connecting the carbon tubes! It rode like a slightly trained jellyfish but it was very light for its time. Finn. Denmark
It would be interesting to compare it with s-works and prove (or disprove) that you pay extra hundreds not only for difference in the paint job.
I have also cut a Venge in half. That was an interesting video. I think it's going to vary frame to frame if I'm honest.
Very interesting videos - thx for the effort!
What would be interesting to know/see is if the cheaper carbon frames (from the major big manufacturers) are just heavier or if they are also inferior in terms of durability ie impact resistance and ability to have more flex in the frame because of a thicker carbon layup.
What I took from Rob's comments about the Canyon bike you chopped in half, is that a higher end Carbon bike generally means a lighter, stiffer frame which of course gives you more performance but what if you are not racing and care more about comfort and durability? Would it maybe even be beneficial o go with a lower end Carbon bike?
This is not a Tarmac elite (sl4) - like you had on the screenshot. Your cut frame is a Tarmac SL6 sport disc.
Not understanding the process of Carbon Fiber layup is a mistake in almost every analysis video on you tube. The difference in the carbon fiber series for strength and rigidity is a serious scientific fact that is not addressed in this or Hambinis videos AT ALL. The Trifox frame most likely is a T700 composite and the Specialized is a T1000 majority composite fabric. T700 frames require more material to achieve structural rigidity. There are many Chinese brand T900 or T1000 frames that are dirt cheap and compare with high end manufacturers. The U.S government lobbied the Japanese government to restrict T1000 carbon fiber sales because of supposed military application use during the Trump administration. The T in the series stands for TORAY, which is the leading manufacturer of carbon fiber fabric and composite resins.
Not to mention all they think about is the shape, and thickness of the carbon layup as a determination factor for structural characteristics. These folks have no understanding of CF layup matrices and different layer directions to determine its structural characteristics.
@@shinn43 Its a weird you tube format to talk about something which there is little understanding in the information age.
@@shinn43 It's not easy to tell what the exact layup is when dissecting a frame like this. Voids and obvious defects, as well as extremely thin carbon areas are easy to spot, so that's what's discussed. It literally doesn't matter what layup you're using when there's a giant void
@@KekusMagnus Yes I agree with you that voids and defects can inform us of brand's manufacturing quality process and this is the extent of what can be analyzed (visual)
There's higher T1100 now I believe.
after you cut lots of frame, you can make a comparsion database. and as I remembered the carbon frames of specialized and trek are also made in china.
Calling Specialized frames "Premium" is just a way for S-Works owners to believe that have "Super-Elite-NASA-Pro-Exclusive" frames.
Please make video about the carbon frame thru axle section ❤
That's my bike lol! First carbon I've owned, bought it used last year.
No way! What are the chances... How are you finding it?
I SAWWED THIS BIKE IN HALF!!!
…Looks like a job for flex seal.
Would be a travesty but would like to see a Time ADH cut up if you havent already done it. Be nice to see if their wax mould and carbon sock weave process is as good as claimed
Hey Jourdain, love the content!
Just a tip if I may, - your viewers are bikers and casual commuters mostly - notice that the mentioning of Trifox is excessive as we're the majority so mate, just give yourself a lil slack! :D Nice idea for a channel, enjoying all the videos! Shout-out to Rob for the cuttings - would also love to see a cut-up of disc mounts, but perhaps I've overlooked 'em 🤷♂
Would you mind doing a Trek? Perhaps an Emonda / Madone / Domane.. Anyways, great work guys!
As a commuter cyclist i will keep my Allez Sprint Comp 2017. Greetings.
Get a spare headset as soon as possible.
@@yonglingng5640 Get a spare headset as soon as possible? why?
@@fernandocycling9662 The first-generation Allez Sprint uses a proprietary zero-stack headset. Not even Enduro Bearings have an aftermarket counterpart (as of now). You definitely don't want to be caught in a position where you can no longer buy it due to it being completely sold out. I doubt Specialized is still having it manufactured, so it's better be safe than sorry.
@@yonglingng5640 you may be right, but i bought this bike new, and never did have any problem with the headset. Thank you for your info.
@@fernandocycling9662 The bearings will wear out one day, it's only a matter of time.
Craigslist: Specialized Carbon Fiber frame, good condition, barely used, not damaged.
That's hilarious! 😂
The seat tube is actually the least stressed part of the frame. As are the seat stays. I think you all might be over thinking or assuming the manufactruers are more performance focused than they are when it comes to all the tube shapes and thicknesses. These days they all more or less do the same things with their frames. Unfortunately the game is more about distinguising the look as in its design.
Any carbon frame with the thinness seen here and elsewhere say like in the head tube, bottom bracket and seat tube area are all going to be prone to fatigue and much sooner than if those features had been reinforced. In all honesty that is what makes a race frame a race frame. The life of the frame is compromised and fatigue over say years is not the issue, since, the manufacturers see these frames as replaceable.
I'd never buy one of these carbon frames if one was hoping to have it for 10-20 years. There are independent makers who do carbon to last but they aren't so concerned about weight. The thinness of say the bottom bracket shell and any tolerance which is off is likely to creak and dare I say I have encountered more people with frames from the larger companies which have these issues than say ones from the indies. That said carbon is an old material now and not exactly progressive or state of the art so I am always surprised it still garners so much attention in the industry and how racers and even just riders get sucked into believing it is superior.
As for the thinness issue with say something like a top tube, well, just think what happens if your bars fling back without too much force as they might do in a small crash or even just in transit? I don't want to sound like a luddite as I have a carbon frame myself but there are alternatives to these more fragile frames that are not built to last and really only add little to no improvement over say a thoughtfully crafted frame by any number of individual makers or smaller shops.
The most shocking thing about these frames are the selling prices. They are virtually all cheaply manufactured on mainland China and then sent to Taiwan for finish to give the manufacturer tax breaks. They are not even custom, yet they are charging prices as if they are some boutique high quality manufactured custom frame. For the silly prices that Factor, Specialized, Trek, etc... want for their cheaply fabricated mainland China made cookie cutter stock framesets I could literally get something like a Pursuit Cycles fully customized CF frameset built in the US by an artisan (Carl Strong) and that frameset would be customized to me, not some stock cookie cutter bike.
@@rcg9573 I agree it is upsetting how many riders will keep switching frames out for what the industry brings on as the new style every year etc. I don't know why more people aren't into the idea of getting a handbuilt frame in the US that will last 20-30 years over these offshoring brands. Plus many of the smaller builders give you a 25 year warranty on the frame itself! My Calfee is going strong at nearly 50K miles and all the specs like the bottom bracket are spot on so no issues there etc.
@@rcg9573absolutely! They are way overpriced.
@@speciesofspaceshow long is a bike suppose to last? 🤔
@@kalijasin material like titanium a lifetime and in terms of standards there really isn't any reason why some of the old standards should ever have to go away etc. 1 1/8 head tube isn't bad and 68mm english threaded BB works just fine. But carbon does fatigue. However I am sure most people who replace their frames do it because they want something new and not because it needs replacing.
can you make a video reviewing the Dare VSRu frameset? I think it's also a chinese rb brand and I'm planning to buy one but the frame itself cost about $3000 so I want to know if its okay and I'm not wasting my money. Thank youuu
can you guys cut a holland frame with uses military grade carbon, would be very interested to see how quality is compared between that and specialized
Hey Jourdain, just wondering if it is easy to mount the Di2 battery on the Elves Falath EVO
I used bubble wrap and some extra foam to stuff it in there
@@GCPerformance18 Ok, Ty
Thanks GC 👍🏼
Sticking with titanium with steel forks, No enve boost in my list😮
Hi thx for making this awesome video I love it. I would like to know the thickness for the bike frame(the top part of the frame
)
Thanks let me know
👏🤞😃
Thanks for the video, but I am struggling to understand that this is a 2015 Specialized Tarmac Elite SL5, as you show in the beginnning of the video. The frame you're cutting up has dropped seatstays, something Specialized introduced from the SL6. Also, there are disc brake mounts, another feature first introduced on the SL6 Disc, which was released in 2018 and with new colorways in 2019. Pretty sure that is an SL6 Disc. Probably the "Sport" version.
I sawed this boat in half!!
My heart breaks a little every time a frame is cut 😢
Me too... Luckily these frames are already a right off so they have no use anyway 👍🏼
These videos are so interesting, thanks for this awesome content
Glad you like them!
This video makes my nose itch
Hi there!!! which one would you suggest, aluminum or carbon frame?
I prefer carbon for sure. It depends on your needs but I have always gravitated towards Carbon. Much better absorbing shock and vibrations .
Good job
I have a couple of Parlees. A Z Zero and an old CX that I don't use. On the one hand, it makes me a little morbid to see what it's like inside. But on the other hand, it would be a shame to break a frame that can still work. What a dilemma. What What I can say is that carbon and its lightness-stiffness is more for professionals or people who move a lot of watts. Most of us would go the same or better with a good steel or titanium. I have a 953 stainless steel and a titanium Baum and I like it a lot the feeling of metal on the road. For the mountains I am not considering a double that is not made of steel. And a hardtail that is not also made of steel or titanium. Carbon does not interest me in the mountains
No respirator? Now you have lungs with a carbon fiber lining.
Interesting to see that de lamination occurring in the top tube - makes me wonder which version Tarmac Elite this is and what happened to it to put it in the graveyard. As an owner of Specialized bikes i find these dissections especially intriguing.
2015 specialized tarmac elite sl5
Glad you enjoy the videos 👍🏼. I would be interested to know the background as well
Top tube damage would probably be from falling over onto a hard concentrated object like a pole or building corner, or from sitting on the top tube while astride the bike at a stop.
It's just plastic, technically
This is from Giant's factory in Taiwan.
Here's what I ride:
1997 Bianchi Ti Megatube (titanium) with Campy Record 10 NOS and Campy Bullet Ultra wheelset
1995 Tommasini Velocista (Columbus MAX steel) with Campy Record/Potenza and Campy Bullet Ultra wheelset
2021 Niner RLT 9 (Reynolds 853 steel) with Shimano GRX800 and Campy Levante wheelset
No cheap Taiwan/China carbon!
You do the right thing. Same here. 5 bikes, all metal. 6th was stolen though.
Test Giant Tcr Sl framset
6:50-7:00 whats that noise ein the bachground? sounds like someone walking in minecraft.. on the gras lol.. what is that ?
Good question... I 😂 have no idea. Probably something in the edit or something rubbing against the dead cat on the mic
Cannondale next🙏
Maybe scalpel si
I haven't done a Cannondale yet... I'll see if I can get my hand on one 👍🏼
@@JourdainColeman a friend of mine just broke her supersix evo cx, maybe I can get her to donate it
Hi Jourdain,
That video is very valuable in understanding the frame's structure.
Have you measured with a caliper its wall thickness? I would be very interested in knowing that parameter.
Another important paramrter is the texture type of the frame. Can you tell any insights on that matter?
Btw, you can find more data on its structure if you slightly burn the edge of the parts which will delaminate the layers - this will tell you how many layers are there. Would be very interested to know the result if you do so.
Thanks!
I only have a 218 USD used bike 😅
It’s not a $1,000 frame because you can’t buy it alone. You have to pay a lot more. However, I suspect the frame costs $300. Add $50 for the paint.
🤣
Hope you guys are wearing masks while cutting carbon
That's what I said immediately!
but but but. all these Big Brands are. made from same factory in Asia😂
Do mtb frames next time 😅
It would be interesting to see the comparison
Reynolds 531 steel frame and fork best😀
I have a 501 frame and love it! One day I'll get a 531 frame for full restoration 👍🏽
I was shocked 😯 by how easily you could cut through it.
Steel is real.
Its almost as if the specilized bike comes from the same place as the giant. Almost.
You said its carbon, but for me is a plastics. 😂
This video is an ASMR of youre chest hair :D
😂😂
Damnnnn😢😢😢
Carbon carbon carbon it’s around years so come on what is the next evolution moving on from carbon.
Always keeping you buying something new.
wont be riding that one again..
A bit a super glue and I'll be good to go 😂
@@JourdainColeman i dont know why people get so het up on carbon fibre frame repairs.. These things are easier to fix than say steel or Ali frames, which are normally a throw away job.. just rub them back, clean them and patch..
Pls cut twitter frame
A few people have mentioned Twitter frames. Do they have a good reputation?
Fiber carbón is the worst material for bike frame.
Do you know is illegal what you are done. The company can suit you.
huh???????
How?
All the more reason I would never buy a carbon fiber bicycle.
cut up a specialized enduro frame..........please!
uuuuffff, parece que el objetivo es atacar el material del carbono. Yo creo que no hay necesidad de mostrar las imágenes tan grotescas de como cortan la bicicleta tanto con segueta o con las otras herramientas, el objetivo es analizar el material y como esta compactado, no la forma tan fácil en que pueden ser destruidas. Eso me parece muy bizarro y el verdadero objetivo de sus videos, ridiculizar a los usuarios por lo que compran a altos precios y que como lo cortan lo hacen ver como basura prácticamente.
Si tu objetivo es mostrar los gruesos de los tubos puedes ir directo a los análisis con las partes previamente cortadas y solo ilustrando la forma en que cortaste de manera precisamente ilustrativa no para torturar a los visitantes.

Interesting video, if not a slightly painful to watch montage 🫣 I've just picked up a 2021 roubaix frame, have you cut ones of those up?
I have not, but I'm looking for more to cut 👍🏽
Not surprising that Specialized and Giant are similar, they are made in the same factory.
Specialized made in Merida
Carbon is junk, buy metal frames, any metal.
bravooo
Glad you enjoyed!
I wish I had this bike🥲
I know this is for Science and vidoes, but mna if you have exstra frames 🌚
Work for it
if you ever have the chance , check a carbon frame from ''TIME'' . they are really on an other level regarding the construction of their frames
Yeah, I've seen quite a few good reviews of their frames. It would be an interesting watch
