Almost every major brands lower end carbon frames are built the same way - lots of carbon and heavier (almost to the same weight as AL) compared to their highest end models. Usually also made in the same factories as well. Carbon is actually a very cheap way of manufacturing, the expense mostly comes the mold and prep we really shouldn't be paying the absurd prices bike companies charge for them.

Yes. It commercially costs 10,000 USD for a mold. To a factory, it is probably less than half of that.A mold can make 50 Frames. The carbon costs next to nothing. With very cheap labour and costs, factories are spending $150-$200 to make a frame

Radius on the fork assembly has nothing to do with the deflection of the fork. Resistance to deflection depends on the flexural rigidity (EI) and the stiffness of the end connection. Flexural rigidity is increased by either increasing E (Young’s modulus) which is a material property or I (The Second Moment Area) which is determined by the section dimensions and material thickness. Both forks have similar external dimensions, so it is very likely that the cheaper fork is thinner and or is built from a lower grade of carbon fibre. Is that a problem? Well it depends. Providing the fork is rated for the potential static and dynamic loads it will experience it is unlikely to catastrophically fail even if it’s flexible.
@philhunt1442

Can load rating be calculated by determining the Young's modulus acoustically?
@donharrold1375
@donharrold1375 Жыл бұрын
@@philhunt1442 Simple answer is I’m not sure. Are acoustic methods reliable for composite materials? Not sure why you’d want to do that unless you were uncertain about the source and provenance of the material in the first place? In that circumstance I’d be a little inclined to be wary. What I was describing above was design properties. If you want to confirm the structural integrity of something that already exists then load test it with loads that are comparable to what it will see in service and follow that up with visual inspection and NDT. If you are designing using material that has uncertain properties then take a conservative approach (build in significant safety margins)

@philhunt1442 Жыл бұрын
@@donharrold1375 Ah, I see. I think modal testing is indeed reliable, simple and straightforward and is a great way to get exact stiffness values for custom wheel building, for example, using hooke's law you can derive stiffness from an experimental frequency result of an object by squaring it and multiplying by mass. This negates the potentially destructive nature of limit testing along with many other benefits to the traditional design process. But also useful to test and compare cheaper overseas production vs domestic and determine which parts have negligible differences in strength.

@@philhunt1442 Thanks for the interesting observations and comments; not sure I understand them all, but it’s always interesting to hear different takes and opinions. One of the interesting challenges of manufacturing bikes (essentially consumer goods) is the need to optimise strength, stiffness and aerodynamic properties whilst minimising weight, without creating an impractically expensive or potentially dangerous product. Control over details is critical. Buying direct from Chinese factories gives me a degree of anxiety because of the possibility that manufacturing and cost compromises might unwittingly lead to a product becoming unsafe. That could happen with big international brands too, but qualified management systems make it less likely.

Given a rider weight of 65 kg, two bicycles with weights of 8 kg and 8.3 kg, and a 7.8% incline over a distance of 1 km, we can calculate the following: Bicycle 1 (8 kg): Average speed = 24.7 km/h, time to climb = 2 minutes and 25 seconds Bicycle 2 (8.3 kg): Average speed = 24.5 km/h, time to climb = 2 minutes and 27 seconds So the rider on the 8 kg bicycle would climb the 7.8% incline over 1 km in approximately 2 minutes and 25 seconds at an average speed of 24.7 km/h, while the rider on the 8.3 kg bicycle would climb the incline in approximately 2 minutes and 27 seconds at an average speed of 24.5 km/h. Thats for a rider with 400w watt output

This carbon explanation gives me new light in tonwhat actually could have happened to the Titan submersible when it imploded on the way down to the Titanic. Someone could have very well over stressed and over torqued a component that was attached to the carbon fiber tube and caused fractures in its structure. Carbon can be somewhat forgiving but once it's damaged, it's done.

Not necessarily, when the wheel is fitted the through axle essentially turns the arrangement into a square box which is very stiff, the forks won't be able to flex relative to each other. Thinking about it mechanically it might have slightly lower stiffness laterally but if there's that much lateral load going through the bike then uh... You probably have bigger things to worry about 😂😂💥

I’m enjoying the bike so far kzbin.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.

absolutely missing the point here. We buy a branded product because branding assures a level of accountability. With a Trek, Specialized or Giant there is always someone reliable to go back to if a problem occurs. A big brand is not going to risk its reputation (and survival) by putting out crap product, because rectifying problems will cost them dearly and puts them at a competitive disadvantage. A recall can easily cost mullions and can't be insured against. With unbranded products the cost is lower because the supplier does not have the costs of providing accountabiliy. In order to be fully accountable, and survive in business, a brand needs to invest in testing, quality control, liability insurance, and a network of distributors and dealers to provide service. To get dealers, and consumers prepared to pay the premium prices necessary to cover these costs, they also have to invest in marketing in the form of advertising, pro team support, etc. Marketing costs big money. With discount price, unbranded frames there is none of this. It's the wild west and the consumer is taking a great risk. There is little or no accountability, and consistency can be an issue. Carbon frames are laid up by hand, so no two frames are ever identical. Cutting up one sample to look inside will tell you far less than finding out whether you're likely to get paid out in a law suit if it fails and hurts you, and wherther there will be a global recall to prevent it happeening to anyone else. The mainstream brands have a vested interest in not hurting their consumers! This stuff is all that keeps your chin from being ground away on the tarmac. Buying cheap, unbranded products is a mug's game. Caveat emptor...

As a few others have also pointed out in the comments the fork flexibility test really has pretty near zero application to what the fork does in real world conditions. Based on the exact same criteria the cheap bike that has a 3mm thick top of the top tube is obviously far superior than a Canyon et al that have a super thin flexible top on the top tube. That test of the forks is about as informative as a GCN free hub sound check. If the spacing for the front axle isn't exactly spot on then having some flexibility built into the profile would be beneficial as to force the arms of the fork in or out will be pre-loading the forks and creating an unneeded stress. Other than that Rob's gear and analysis was a fair eye opener.

Yeah the fork test is arbitrary really. It's interesting to see how the radius of the fork and carbon effects this stiffness. You may like this video if you are interested in the carbon stiffness etc. I compare a canyon to the trifox - kzbin.info/www/bejne/poqlimpuYt-mbbM

That 3mm thick top tube isn't necessarily thick - if it has air pockets and lose strands of carbon all over, it will be flimsier than thin Canyon top tube.

I've learned enough with my experiences over the years that carbon doesn't belong on any of my bikes. You want carbon and are willing to take the risks I wish you luck, but it's got to be made of metal for me the rest of my days.

@Charles Man Wing surfaces are a major area where carbon fiber is replacing aluminium. Not much stresses and it's actually lighter. Some planes are using carbon fiber in the fuselage as this is another area where weight can be saved.

@@charlesmansplainingaircraft parts like the entire horizontal stabilizers for large je liners or entire wings and large part of their internal structure... you can look up the flex test for aicraft wings.... the carbon wings of the most modern jets flex many meters... In cars its anything from body panels, parts of the car shell, supercars use carbon for the entire mocoque, high end race cars lik F1/F2/F3 or the endurance racing LMP cars are made out of carbon fibre monocoqe and carbon/kevlar body panels... even stuff like control arms, prop shafts for over 1000Nm are made of carbon... The list is pretty much endless from sport equipment to medical stuff to cars planes bikes safety equipment like helmets or crash structures in many aplications.... cars and planes use carbon brakes sure its different technology and type of carbon but still a carbon...

The video could have been considerably shorter (and better) if you didn't make cuts every few seconds where you just repeated what Rob said. Higher end carbon frames are great and are every bit as good as big brands like Spez or Cannondale. Entry level carbon frames are a bit of gamble. Especially something like Trifox/Delileah/TFSA as TFSA is the actual OEM behind them and it is not a very reliable manufacturer - QC is all over the place and they tend to copy frames without having a second thought (i.e. x18 frame being a direct copy of Tarmac SL7, including the faulty headset design).

I'd love to cut up a well known brand frame. But they cost 3x as much. This video I lost around £500 so with a well known frame that would be more like £1500. It would simply cost too much. Maybe one day I'll be able to do that... I should start a Patreon 🤔
