I Cut a High End Specialized Carbon Fiber Frame in Half... Here Is What I Found!

We're going where no bike enthusiast has gone before - straight into the heart of a Specialized Venge frame! That's right, in today's video, we've teamed up with Rob from Carbon Bike Repair to take a wild ride into the world of carbon fiber road bike frames.
Join us as we investigate the specialized frame quality and construction by cutting the carbon frame in half! You might call us the "surgeons of cycling" or the "doctors of derailleur destruction." Whatever you want to call us, just be ready for some unfiltered, unadulterated bike knowledge and banter!
We're not stopping there! We'll be pitting the bisected Venge against two other carbon frames: the sleek Canyon CF SLX and the cheap Chinese carbon Trifox X10. How do these carbon creations stack up in this epic battle of the bike innards?
So, if you've ever wondered what's inside a carbon bike frame, how a carbon bike frame is made, or how strong carbon fiber bike frames are, now's your chance to dive in and explore!

The bond mark at 7:56 is where the bits are glued together, they are typically made in sections.

That’s exactly why I always say Specialized isn’t high-end, they just sell regular bikes for high-end prices. Their carbon frames aren’t even true monocoque chassis. Vastly inferior to other true high-end brands

@@meteormedia7021 There are many advantages to bonding frame sections over monocoque moulding. The Colnago C68 is bonded, and that is about as high end as you get.

I actually own both the Venge Vias and the last Venge. The Vias feels solid and it sounds like if there is a LOT of material and the last Venge feels like it's fragile and limited on material. Both bikes are ultra stiff but I feel like the Vias will hold its integrity in the event of a crash unlike the last generation.

10:00 the bonded joints may be the strongest parts of the frame. Bonding techniques are even used at the wings of aircrafts. I see no problems there. 8:20 The thickness of a carbon part does not necessarily say something about the stability, stiffness or durability. This depends mostly on the used fibres, the alignment of them and the used bonding resin.

@appa609 Жыл бұрын

The thickness is very important for out of plane stiffness. For a thin shell element, bending stiffness ~ thickness^3. This stabilizes the shell against buckling. The total range of fibre modulus is about 3x between sm and uhm.

I’m enjoying the bike so far kzfaq.infoUgkxMesz3KOGEmwmvyKQfLfrRSUXLFzfVHZA My only real complaints are the brakes and the pedals. I feel like a bike designed for bigger people should have much larger pedals and more heavy duty brakes. I’ve only gotten two really good rides out of it, minimal downhill action, and the brakes feel like they’re already going out. A larger person has more momentum, so I think this wasn’t thought through very well. Also, I wear size 13-14 wide shoes. My feet cramp up on these pedals that are clearly made for smaller feet. Since I’m not a pro rider (and I don’t think many are who purchase this bike) I don’t think that the straps on the pedal are necessary at all. None of this takes away from the enjoyment I get from riding, however. I’ll just head to a bike shop to improve on a few things.

Doesn’t matter whether it is high end or cheap Chinese brand, if they are mass produced, highly likely made in China. The process of carbon fibre is toxic, it cost a lot if produced in the country other than China, India, etc. (they less concern about environment and less labor cost. That means, the manufacturing qualities are similar. Even more, is is possible they are done done by the same production line and even same labor. The only difference is cost down, using less material, less quality control, no continuous improvement plan, and spend less time on reducing error rate. That’s why cheap carbon fibre frame is cheap (and doesn’t care about copyright, and Chimera designed form all other high end brand they made in production)

You won’t get an oscilloscope (3:45) down your bike frame, even to satisfy one’s girlfriend. Presumably the Rob the expert meant an endoscope 😉. To be honest, I’m not sure there is really any value in doing all this - your conclusion that one is stiffer than the other is very ‘Y9 Tech’ (as you put it) - the stiffer one has about twice as much carbon in it so obviously it’s stiffer!

You've made claims of manual modifications post manufacturing, if this is true where's the proof? Hard to believe post modifications are made after the layup is complete.

@georgesj9536 Жыл бұрын

Manual in this case means: they designed the whole layup process, but test riders found some areas to be lacking stiffness, so they reinforced it with these small strips of carbon you can see on the inside. This is a temporary solution until they go for a V2.0 layup in the factory. At that point they'd change some of the layers/weave carbon used. But for now they just glue some extra sheets to the inside, which does the same thing but is probs a bit heavier/ less tidy. But more economically effective than delaying/halting production.

But i will give my Canyon Exceed CF SL 8.0 frame a try, if it holds up i may buy carbon frame in the future again, otherwise allow and call it a day... But as i drive mostly in the city, and some lighter mountain, i think the carbon frame should last... Still i think in terms of durability and cost, high end allow, will get close to carbon frame weight, but it will be 10 times more durable.. That ofc is mostly for MTB, for road bikes, they dont have other option then go for carbon frame, since allow will slow them much down... Guess enduro and DH riders are way better, since they dont care for overall bike weight... But we hardtail and mostly road/ gravel are more screwed, since we look for speed...
