Apologies at the time of uploading, I had not finished the literature, I will endeavour to publish that when I get a bit of time. It's hard fitting it in between episodes of Paw Patrol. It could be worse, I could be having an absolute crap day after getting reamed on social media. Just like this lot www.hambini.com/absoluteblack-700-ospw-leaves-company-reputation-in-tatters/ On the subject of there being differences in carbon type across the frame, that's a totally valid point but a sample that is big enough to test is required. The bottom section of the downtube is ideal for that. This testing is by no means perfect so don't take it as gospel. Overall, the cheap frame doesn't have inferior carbon or resin used. This suggests you are paying for a badge and paintwork. Another question was around having an extra thick section where it was tested. The stress is based on force per unit area so it should account for this. ***I would be interested to know if anyone has any suggestions around testing as this methodology is definitely in need of improvement*** and I would be the first to acknowledge that.

John who donated the Canyon frame. You’re all welcome! All in the name of science and engineering Hambini style!

Hambini, I have no idea about the engineering of these frames but I do appreciate you and others taking the time to explain this all in layman's terms.

Soft closing drawers. Hambini is a person of class as expected.

Thanks, Hambini, for explaining things that the manufacturers and/or media outlets should, but don't. Because they're either too thick themselves, they think the consumers are too thick, or they're all thick. *Or* the manufacturers don't want to explain because that that would raise too many questions for them to answer, which would reveal their own apparent lack of knowledge of what they flog to the public. And heaven forbid that consumers become informed and educated, lest any advertisers are offended in the process.

"Less than a dump." One of the best weight comparisons I've ever heard!

This man is better than my mechanics professor

Anyone purchasing a Trifox frame is clearly on to a winner here, the amount of moneysaving is considerable and provides ample reserves to purchase better components, equipment etc..

Being a Mechanical Engineer makes me more appreciative of how you are trying to explain it to others that aren't in our field. 99.9% of the people don't und really understand this nor do they care. But good that you are trying to dumb things down for people to understand.

Damn it autoplay! Sat in my shed, fiddling with the Mozzy, just about to spot superglue an extra fiddly bit and BOOM...... "HELLO HAMBINI FANS" ...F****G glue everywhere....and the floor goblins got the fiddly bit!! :)

Thanks very much for taking the time to explain this in simple terms. I didn't realise there was a difference between high strength. I had foolishly thought that high strength meant the frame was very stiff. You might get criticized from the know it alls for taking too long to explain it but I am very grateful you took the time to explain.

I love the really technical videos. Thanks to those who donated frames.

Great video! Nice one and thanks from all the viewers to the people who sent their frames in.

I'm so glad this channel came up in my recommended. It's a fun refresh on fundamentals of engineering and actually some motivation to keep looking for an engineering job post uni.

Protect Hambini at all cost!

That was his best “Hello Hambini Fans and Welcome” hands down!

I was waiting for this before pulling the trigger on that shiny trifox frame, thank you Hambini!

This session brought back memories of my structural analysis Prof in my Civil Engineering days. Nice one Hambini, some how you used a cable stayed bridge in there.

Running into your channel was the best thing happened to me in YT, in a very long time.

Hambini, this is an explanation of the mechanics of materials that I can show to my engineering students. Thanks!

Hambini you bloody legend. What a video. I hope it gets you a million views.

Thanks for the informative video, @hambini. The more we can separate the marketing speak from actual facts is always appreciated. Keep the great content coming.

Glad to see your canyon results were ok as i just got an Ultimate. Enjoying the bike so far. Thanks for the somewhat peace of mind.

Thank you Hambini, informative and to the point as always.

this was awesome. great explanation. even a detlef or a simply simon understood that kind of simplyfied basic knowledge! Great one pls give us more!

One of your best videos, thanks for sharing a bit of your knowlage

I'm too well schooled on your videos not to mute you at the beginning 🤣😘 I bought that trifox because of one of your older videos. Such a honestly priced frame

Nailed it! Thanks for making - I'am now a little wiser!

Love the technical explanations

This is brilliant. I've had my share of Chinese unbranded frames, because I don't mountain bike much, and don't want to end up wrecking a very expensive frame. I started getting cheap frames for that reason and they've all held up great. I've also sold them off over the years to friends who were in the same boat, and they are still going. Are they going to structurally shatter into a million pieces like an F1 car one day? Who knows, but I doubt it. My only carbon fiber test was long ago, I took an old carbon seatpost that had a broken clamp, and I crushed it in a benchtop vise. It didn't shatter. It crushed, and I could see the strands of carbon fiber, but it was still together. I always thought it was brittle. Nope. THE PEN IS WORKING!!!!

Great video! Being an engineer myself, I totally agree on the findings. I’d love to see you cut / slice them down the middle and inspect their lay up for quality and defects which, as you point out, has a huge impact on performance. Luescher Teknik does this - he’s not quite as colourful as you but interesting none the less.

Dear Lord I was already expecting the usual big shout, but you still managed to scare me 😂😋

Great vlog…keep up the stellar work…

Hambini: i would like to give a shoutout. They know who they are

Awesome vid! I think I never learned so much in one KZfaq video.

I learned something today. Thanks, mate!

Thank you, Hambini!

This was a very informative video. You're obviously a very good resource for this type of information. I wish more of your videos were like this and less of the juvenile carrying on. Thanks for the video.

This is really interesting and informative, you are amazingly good at explaining for a five year old.

I think i t's a good idea to chop the frames up at every junction, too. So you can really compare piece by piece what's been done there.

Worth a watch for the engineering alone!

Machinery's Hand Book has articles that explain this in great detail. Well worth studying. Cheaper than college credits, at least here in the US. Thumbs up to Mr. H. for introducing some important info.

We've all learned a lot from this and many other videos from you. Thank you! I think it's obvious now that we all want Hambini bike frame in the future. Please make it and disrupt this industry. Instant buy from me.

Thanks @Hambini for explaining everything, because previously I thought only T1000 carbon and above are the best and T800/T700 are crap. Now I have a new understanding of carbon fiber types. Big thanks!

Holy shit. I just found your channel. I’m about to go down the hambini black hole son! Wooo! Your brilliant bro. Thanks for everything

Fantastic video for now, great balance in simplicity and serious technical knowledge, well only now i have start to learn basic mehanics (again :) )

Fantastic explanation👍

Go Hambini! 💪👍

Wonderful video.

I've been pulling carbon steel tensiles and hammering charpys all day then come home and watch this. God I love my life.

So cool. I am so thrilled about gc Performance ab rear dereilleur "Review" 🤘🙏

Hair is looking on point Hambini 👉

Interesting stuff...very educational!

Great video

Very nice video, a lot of effort in this. Took me back to school, so many years ago... The only point I would add is the diminishing point of going too big on the cross sectional area: re the beer can effect.

You're a funny guy absolutely impressed with your craftsmanship

Thanks Hambini, love your detail vids so we can enjoy more our passion by understanding a bit more basic engineering (or wanketering depending on manufactures) 😜

How do you know if you’re a Hambini fan? You turn up the volume at the start of the video instead of turning it down.

I loved the mini biography of the bridge engineer.

Very well said you would make a great teacher.

Bloody brilliant.

As always school is in session and for a 5 year old it was well done indeed. Thanks to those who helped make this possible.

That was cool content! Thanks

Very Interesting!

love the stickers on your oraange board

This video remind me of what i used to see and learn in university haha. Takes me back to good old days. I wish hambini was my lecturer or i was in university when hambini make his youtube channel so i can be motivated to be a good engineer like him.

That was awesome, ty.

Still can’t decide is this the best Chanel on the tube ?

Hambini thank you for all great work please keep it up ! For once its great to see a honest person saying it how it really is about these so called top bike manufacturers and comparing them to the alternative which in most cases save you hundreds of pounds in the process ! As a novice rider I'd like to see your top picks of chinese bike frames and why or had good feed back to suggest 😊

great video as always mate. It would be cool if more people with crashed/broken frames of other brands would send them to you for further comparison. would love to know info about the Pinarello Dogma, Yoeleo, Winspace, Cannondale, Merida etc

Definitely improved that Cervelo frame.

Wondered how my carbon levo puts up with severe abuse with a fairly thin layup, it the size of the elements of the frame . Liking the more professional presentation however I may sue for hearing loss during the introduction, you get me every time😂😂😂

Thank you. Now off to see my Hair Dresser. Gonna check out some localized defects..

shout out to hambini for trashing his own crapvelo frame for us and for making a point, absolute real one.

Awesome video, wished you had a Winspace T15000 in there too, I will keep dreaming of that.

Good video 😊👍🏻👍🏻

i'm always frightened with your HELLO! XD

hey Brilliant work with AbsoluteBlack

Nice use of the suspension bridge! ;)

Good to see a bit of young's modulus.

Videos like this are a real comfort for me who is looking to build a carbon road bike next year. Maybe a gravel bike instead/as well. I don't have buckets of cash to throw down on a 'western' brand, and I would prefer to build it myself anyhow.

Hi Hambini. Once again thanks so much for your time in explainint these matters. Sorry, its gonna be a long message but before going further I popped some SKS rear bearings in the Subaru Outback from what was learnt off yerself years ago.... So, from your vid I've concluded that I won't be going for the Hi Mod afterall and get back to the drawing board on my next frame which will still probs be a Cannondale... Regardsy last 2 frames I trashed I reckon I've just understood why the Alpkit Sonder Transmitter carbon, was so strong when I took the hammer, carbon saw and dremel to it. Yet so weak when going uphill and a bad gear change broke my chain stay. Must have been a bloomin void that they never took ownership for (avoid the dirty Rascals... they sit in the same area of my brain as Crapvelo). I'll try n find the little writeup I made on the topic at the time of smashing it/em to bits. Looking forward to ordering myself a shiny BB fairly soon for the steely. Thanks again Thanks again

I used a hammer (various weights), dremel, carbon saw by Irwin and my Arcteryx walking boots (with me at 90kg stood in em) to stand on the frames... The Sonder had a much bigger cross section and was almost impossible to fracture... The Boardman Pro roadie was in tatters with just a few blows but had a much smaller cross section (mtb and roadie respectively with weights of 900g and 1200g, again respectively)...

Great video explaining strength of CF and design. Analysis using an alternative summary statistics for the stiffness and strength would be instructive. Using the maximum value may be optimistic, "Best case, your frame will break under this load." Finding the point at which 95% or 99% fail would be better, as long as someone other than me gets the remaining 5%, :). Keep up the good work enlightening and entertaining us all. Phil

hambini uses science and facts to refute the bullshit that bike companies claim thru marketing magic. kudos

Glad your Pen is Working

I'm an owner of a Trifox X16 frame, I'm happy with the results of these tests. However Trifox needs to step up their QC in terms of finishing. My frame required sanding of the drop outs to even be able to fit my wheels in. But the worst offender was excess material in the seat tube that required significant sanding and filing to be able to even insert the seat post. Since I've made those adjustments it's been a great frame and rides really well(and I can deal with those defects at the price point), but may not be the best option for people unwilling or unable to modify the frame a bit.

Hambini : "Bruce Lee ". Hairdresser : "Say no more, mate".

you need to do more of this, esp when you call people out like AB. people should know you actually do know something.

Oviously bicycle frame manufacturers can't dazzle us with science and try to baffle us with bs. Very informative clip.

As the owner of a 2007 Giant TCR that went spongy, I can attest to the importance of build quality. And seeing that the attributes of build quality in a carbon frame are mostly hidden, I look for one with the best warranty.

Thanks!!!!

When I think of my racing days there were so many new items that were made very light. Often, they broke. This included stems (Cinelli had a 1R really beautiful$) and light pedals were breaking as were cranks. I am thinking that some of the high end frames may actually be sacrificing some safety and durability as they come closer to the limits of their materials or there design and it may not take a lot for a failure. I guess that is why they MUST have extreme QC. There would be less room for error

Farq me dead, this fella is one smart bugger. Love the video even though I didn't understand half of it. I'm just a simple construction labourer. 😅

Was just watching the first part because I was curious about the frame, went to 2nd part, stayed because I just remembered I am an engineering freshman and I may actually use the info lol

so, now we need Specialized Aethos frame to cut :)

1:50 of course that X10 is a Hambini-special! Look at the matching red-and-black overall!

Biggest takeaway: taking a dump saves more grams than buying a lightweight frame (which is potentially less stiff)

Thanks for the engineering intro! I understood everything :) I knew it was all fluff and thats why I'm riding a winspace aka, Chinese carbon frameset :) I love it.

You've trained me to rip off my headphones when I see a Hambini logo on the intro. Pavlov's got nothing on you !
