Because everyone knows that although that one got caught, the rest did that too or were just about to

Will Specialized update their warranty terms and say 'squeeze tests are not covered by warranty'. Legend has it Colgate are using an SL7 downtube in their next toothpaste tube advert.

Definitely not a good idea, top tubes were never designed to be sat on or clamped in a bike stand for that matter, a lot of frames get damaged this way.

@@Sebmondo Go check the newest GCN video (sponsored by Specialized) about biking in beautiful Bavaria while they present the new SL7. And they sit with their butt on the top tube! :D))))

WOW! They had some serious failures in their quality controls.

@@DaveCM it's why they are called crack and fails

Geez, Louise. What a freakin horror story! My 2006 aluminum Rush SL was still made in the USA. The welds look pretty good. I bought it barely used for $100, 15 years after it was made. The parts were all original and the tires still had the molding tabs on them. Even the crappy Avid hydros still stopped! It still rides just fine. My store sells new Creakenfail/Crackinfails. I wouldn't buy one either. Ive built carbon satellite components. I know about manufacturing quality. I'll never EVER buy a plastic bike.

Why would you press down on it, though? After watching this video.

@@AnttiBrax Because DurianRider, an overconfident mumbling knob head who doesn't know shit about fuck, said being able to squeeze the down tube side walls means the frame is weak and not safe to ride.

@@AnttiBrax ... maybe by accident when riding it or when transporting your bike on/in a car ...

@@PaoloLuraschi Get a $100 travel case for your $6000 bike. 😀 I've never squeezed my down tube while riding and I have long-freaking-arms. Crashes are crashes, you're bike is toast anyway.

​@@AnttiBraxWell, "by accident" I was not meaning a big crash ! Maybe by accident you just drop your bike while it is parked. The issue is that the damage may not be obvious like a dent on an aluminum frame. Do you put your bike in a case when you load it on the roof of your car ? If so this is fine, but I just don't like to take care of all this just to ride a bike for fun. I understand that a pro rider will have different priorities than me, no problem with that !

Also consider that at the wall thickness these bike have, some flex may be better than being stiff and brittle. The ability to absorb some shock should be better than being so stiff that an impact would crack the tube. Thicker walls might ultimately be best, but at the penalty of weight which defeats some of carbon fiber's appeal.

Well fucking said .. We have been conned by the industry . They selling us crap for 5000 dollars .We pay thinking our safety is their priority yet the reality is all they want is our money . Big respect to Ernesto Colnago

@@zaheerkader7426 The bike is not designed for what you want it for. That means you should buy another type of bicycle.

The average consumer doesn't have this bike bro. If you want a tougher bike you get an aluminum gravel bike for knocking around and keep the carbon roadie for nice dry road rides.

@@Aholeintheozone Steel is real.

New Scott Spark use it as a selling point, top tube thinner than a credit card apparently.

Many frames in the past also had a cosmetic lair of 4k weave over the UD carbon. The frame was a little heavier but probably better suited for us recreational cyclists.

My first thought watching this

lol me too

it's the bubble wrap effect

@@danielmoorhouse6506 Oh, that guy, haven't heard anything from him recently. He needs a squeeze in a couple of delicate spots that might smarten him up.

If you pushed one of your spokes you could bend it. Does that mean you don’t feel safe riding your wheels?

These frames aint light. Bikes from 5-10 years ago r lighter because these days the pro level bikes are optimized around 6.8 kg leaving heavy bikes for consumers

Also the ultra light frames used by professionals are one off's and are maintained by top tier mechanics. They tear down and inspect everything during maintenance and if something is even suspected of being compromised they replace it.

Correct. I see a lot of people in my area who ride 10k+ Pinnarello, Cervelos, SWorks etc who look like they're 40 lbs overweight and they plod along at 13 mph at 50 cadence. Its like they think obtaining speed is as simple as opening their wallet. As most of us here know, its mostly the rider.

Don’t get me wrong I would love to try one and I suppose loads of supercar owners are terrible drivers too but as long as they keep splashing the cash the goodness eventually filters down to us meer mortals so I guess dentists lawyers keep the research and development funds going by buying the best🤔🤔🤔😂

@@daryl4841 so? Does the fact that someone who enjoys his time riding a 10k bike annoy you? Lol why don’t you sell your house and live in a rented apartment? No one needs a house to live after all; all you need is a small apartment to stay in. Its what you do in said space that matters, not the house itself after all, right?

🤣🤣🤣🤣🤣🤣For the fans

No. All because of road disc brakes!

Isnt the point of this video that, even if it was thick, it's still not a good idea to go around applying loads that it's not designed for?

@Mr T ok, don’t learn anything 🤷🏽

@The Puertorican Cyclist I feel u🙌🏻 No squeezing any frame, yes, but those 300 grams comes in handy to ad some carbon layers in a frame, no doubt.

How many real bike incidents caused by carbon failures do you really have heard of? All is said here in true in thoeory, but in practice carbon bike are super safe, IMHO

Thought the same way, until I got my lightweight aluminium frame. Nice bike, but in no way more robust than a carbon frame. Drop a carbon frame on a sharp edge, you might get a crack. Drop an aluminum frame on a sharp edge, you will get a dent, that might buckle. Same thing basically.

@@kilianortmann9979 I chose to make my wife a custom CF touring bike precisely for this reason. I'd seen too many of those fat-tube, thin-wall aluminum frames damaged, as well as carrying numerous work-hardening cracks near the welds. I chose CF not only because, done right, it's perfectly capable, but because it's so much simpler to DIY and far far safer than welding. Of course, I didn't try to make it weigh nothing by sticking with minimal structural strength at the cost of crush resistance. So far the only catastrophic failure on the thing were *aluminum* bar-ends that tore right in half when a car cut her off at an intersection and she dropped the bike.

As is the case with the top tube on many a CANYON bike. If you have damage, you can extend it to "beyond repair" if you stress it further.

Some bikes gets their stiffnes, strength etc. from the sides of the frame, so when pushing limits on how light the frame is going to be some areas only needs material to ”fill“ out the shape. Like the top of the top tube. However Basso for example put extra material there only for you to sit on during coffee stops, I think! I imagen a Canyon being flexy in that area and a 2015 Emonda too, still nice bikes…

@@mariusilerd9581 I hear you. Still stand by my point. These bikes aren't safe unless your a pro with a mechanic making sure everything is intact before every ride.

They fair much better in a pro peleton with replacements at hand yes! They also get abused more, Im fine with babying my bike so to speak, but it doesnt have a integrated handlebar nor the flex problems they talk about

Your organs can fail with a good press from the wrong angle. No way it’s safe for actual usage too. Actually, your brain, based on the words it’s directing you to say, probably is long expired too .

The SL7 is the only S-Works downtube I can compress a lot. The other tarmacs just resist because they are made for racing vs posing.

@@johnsmith1474 🤔😜

@John Smith 🤌🏻

Agree, that’s why I ride a titanium and steel bike. I have a cut tube of titanium, the same as the one on my bike. It’s less than 1mm think, probably 1/4? Anyway I challenge people to crush it… even though it’s an empty tube cut open at both ends nobody has been able to deform it with hand strength.

or a bump in the road

Bruh a bump in a road is different, did u not get the point? Its not designed for the «thumb test» but they are designed for bumps on roads🤦🏻‍♂️ Smh

You gotta be like Joseph Gordon-Levitt in Premium Rush predicting all the scenarios in a split second so you don't ever crash or fall over.

Different kinds of impulses; you aren’t constantly applying pressure perpendicular to the direction of the fibers when you crash; you’re bumping the bike. Very different things from an engineering point of view

It won’t and that is why there are many carbon repair places around

Not really race spec steel tubes are extremely thin in the center sections, seen many dented beyond use, and Alloy frames even back in 90's were getting extremely thin! My Yeti arc top tube could be dented by squeezing it with your fingers. Or worse my mates Cannondale caad had the brake lever tear through his top. If you want lighter frames it comes at risk no matter what the materials

Most household items are easy to break if you try. You can easily bend you laptop screen backwards, snap your glasses without really trying, etc. doesn’t mean they’re low quality or bad products.

You need to work on your comprehension skills. That's not what he said.

pressing abit is ok,even after notice can squeeze welly must as well thrown the bike get a new one,life is short chose to have a quality

Yes. I totally agree. Imagine if a rider goes over a bump and comes down on the top tube with his weight. Such shearing forces could be generated and start to delaminate the top tube and result in the rider losing control. I don't know what happened to Fabio Jacob in the 2023 TdF, but his bike split on the top tube, no damage to the wheels.

I have seen these crack at the top tube from this type of force.

So Specialized are charging how much for a chinese made carbon frame that cant handle being squeezed for Tiktok but somehow is meant to handle a 120kg fat keto barrister hurtling down Greenhill road over the potholes no probs? Specialized should do a recall on that bike!! Oh wait...

@Mr T The point being made is not about the possibility of being able to squeeze the tubes but the lack of awareness that it best not too try it. I agree with you that it's not necessarily a bad thing but some see it as poor build quality.

Agree. Most people buy based on other (percieved) qualities than those relevant to them and their use. At least a seriously flawed weitghting of them. For me it is far more important that a bike survives falling down at a cafe stop, or getting slammed by the door on my way out of the house, or traveling on a roof rack on a car, than those 20 extra grams of weight.

Cyclists truly are the stupidest of breed... This comment section is my proof.

Yep, warranty is gone. That frame is toast and heading for recycling (or eBay). :D))

Yep I wonder if the reason why it is so flexible is because he has been squishing it so much. I wonder if he also tests avocados the same way, this one is bad, this one is bad.

@@LucasHynar yeah his frame certainly seems to have a lot more flex compared to other peoples “squish test” on the SL7. He may be the reason why all the avocados at the supermarket are always bad haha

Have you EVER hear about “double butted” or even “triplle butted” i can recall which frame was but i have seen aluminum bike frames with different wall thickness around the circumference... yeah, metals are isotropic in books, treat and triple “but” a aluminum tube and do some test to see if it remains isotropic

@@pannnda1 There is also hydroforming, which is usually done on higher-end aluminum frames. This can lead to better optimized strength and rigidity in the desired direction, as well as improved frame aerodynamics. Double and triple butting results in more optimization as well, by making the midsection of tubes lighter. However, within the thin midsection, the tube will remain isotropic and equally rigid axially, circumferentially, and radially, with the associated strength and toughness in each direction also equal. So there is no weak plane that will lead to catastrophic failure in the event of an impact to the midsection, unlike carbon fiber, which is susceptible to shear failure between the plyes.

@@johnbarron4265 how hydroforming will help to have better aerodynamics? If you have 2 tubes both with the same shape and one made by hydro forming the aerodynamics of both tubes will be exactly the same If you have a tube with x lenght and along its lenght the thickness of it changes the properties of the sections with more or less thickness will change aswell... also i have seen more trashed aluminum frames than carbon frames due light handlebars impacts (classic top tube) breaks hitting diagonal downtube etc

@@pannnda1 There are also more Toyota Camrys trashed in auto accidents every year than Ferraris. Does this mean Camrys are less durable than Ferraris? LOL you can't really expect to be taken seriously with that anecdote about alu frame breakage.

@@johnbarron4265 sorry mate, alu double/triple butted frames aero optimized hydro-formed are almost expensive as carbon frame...

Good question, typically hybrids with Dyneema, Kevlar etc are used for vibration damping or to reduce the possibility of complete separation of parts, so could possibly save a catastrophic failure however would not reduce the initial damage. These fibres also have lower compressive strength so clamp damage is more likely. Best is probably just to put more carbon in the area.

Or titanium or steel. These new carbon frames are being made so thin to make up for the added weight of disk brakes(flack incoming). Also average riders are probably a lot harder on there bikes than pros. Because pros just replace their bikes like we change underwear lol. Us regular folks are lucky if we replace our bikes every couple of years.

You can break an egg one way fire to and not another direction easily, that's a sort of way a CF frame is.

a dent at the worst on aluminum tube

Do it to the middle bit of a modern "almost as light as carbon" alu bike toptube, and you will dent it. Seen it puncture on point-loads.

So did my Titanium frame.

How's your thumb 😀

I have them for sale at my Teespring store.

Surely, if all that one needs is a stupid video like that to cause you to make such an ignorant statement - there’s something fundamentally wrong with your education system.

Congratulations! 🤙 That was definitely the right choice-one of the best materials to build a bike! Would never go back to carbon for that few grams of weight saving....

@@87togabito whatever mate. Suit yourself. I'm not a pro, never was, never will be. No need for a bike like that. And I stand by my original comment anyways. If all that one needs to cause permanent damage to the frame is to squeeze it with a thumb nail - then the design is just flawed and you won't convince me otherwise. The frame is never only getting loaded in the exact way designers assumed it would. There's transport, cleaning, maintenance, occasional accidental bump or kick. Don't tell me that it's ok to design a frame which is soooo "optimised" that doesn't have structural redundancy to take such instances. Maybe, but it's a huge maybe - for pros - but never for general public! But given that UCI insists that each piece of kit they race on must be commercially available, then it's just outright wrong.

It does matter. Doesn't mean you should, and particularly not if there is damage/imperfections (and there always could be). Not designed to take on axis point loads is what I got from this.

There are various ways in which a force can act on a material: tension - a pulling force compression - a pushing force bending - forces at an angle to the material torsion - a twisting force shear - forces acting across the material A material can have very high strength in one type of loading, and very poor strength in another. A cable has excellent tensile strength, but doesn't resist compression. Ceramics generally have very high compressive strength, but very low tensile strength. Spoked wheels need to be properly tensioned so that the spokes are kept in tension and are not subject to compression (and the rapid stress cycling that comes along with the compressive loading of spokes). A structure (in this case a bicycle frame), is designed to resist certain forces. The same is true for any other structure: bridges, buildings, bones, etc. The ability of a structure to withstand forces outside its design spec is mostly good luck, but the more you optimise and reduce the weight, generally the less likelihood there is you'll be lucky. When you remove material you generally are weakening the structure, with regards to the ability to resist a certain force in a certain direction. That a frame can be damaged by very small forces outside of its design spec is far from ideal, it makes the frame delicate and easily damaged. That said, the fact that a frame can be easily damaged in this way doesn't mean that it isn't safe and adequately strong for it's intended purpose (when undamaged) just that it's easily damaged by forces it wasn't designed to withstand. This is a mostly unavoidable on ultra-light components where you're looking to shave every possible gram.

It depends on how the bike is made, however I would not recommend that on a light frame.

​@@LuescherTeknik Thank you, I feel more comfortable going for the heavier domane, crossing my fingers trek didn't forget some resin somewhere.

I would worry unless you it with a death grip. Obviously it's not wise but there's squeezing and squeezing. You could get your frame scanned if you are concerned.

@@glennoc8585 Thank's Glenn. Last time, i don't press it super hard, so a bit hard but just with one hand. Your advice ?

The stiffness is in the other direction, think of it like an egg or an empty toilet roll or something similar, those items are very easy to crack/deform when squeezing from the side, from top to bottom though they are much stronger/stiffer, much harder to crack an egg from top to bottom than side to side. So frametubes are much, much, much stronger in loads between headset and bottom bracket / seat tube, and ofcourse the triangle that the frame creates adds a ton of stiffness. Look at paper bridges that some engineering school creates for competition, who can create the stronges bridge out of a given set of paper, i saw one that could withstand over 500kg (search for "paper bridge"). So that bridge is incredible strong in the direction that it was design to take the load but you could still destroy it with your finger & sideload. So yeah, just because something seem weak in one direction doesn't mean it is weak in all direction, it totally depends on geometry & what type & what direction of the load it is designed for

I agree... but for a bike that is going to receive regular real world use toilet paper and eggs might not be the model. Also TP and eggs are at a very different price point.

@@cjeesewalburge5820 and egg shell is meant to protect the unborn chick from very real world dangers. Your point? The bike is designed to take the damages it will see. A stupid finger frame press, isn’t one of that. You can’t design for stupidity.

Maybe its actually just a thin walled piece of crap 😱

Ive eaten my weight in popcorn this last week haha.

I said don't ;)

No its not logical. Which follows tradition, this is the same bike industry that used to put 53/39 on all bikes, and tiny skinny rock hard tires. Stuff that is not appropriate for 99% of people.

I think its this obsession with lightness that's driving this ,even though aero beats lightness unless you commute up a mountain daily.

It is logical. If it instantly delaminates and breaks apart like Raoul said about the Stork frame then... it was improper handling and a new frame has to be purchased. Kaching! In that case there is no warranty due to customer abuse.

The concept is that larger tubes with thinner walls are stronger than smaller tubes with thicker walls. The larger tube can stand more forces. Much the same as Connandale in the past with their huge alloy downtube. It was thinner than other bikes

Diamond frame/ upright bikes are not logical.

😂💦
