Well, I watched the video and a few more. Interesting dude, seems he's an engineer of some sort. The best video I watched was the one on crank arm length, he did some very cool modeling.
I've seen a lot worse video analyzing bike stuff that's for sure.
I give him major credit for calling out bike marketing flapdoodle, particularly in his video about the Specialized SL7 release. I thought he had great insight and didn't hold anything back.
On the materials front? Who knows, but I did send his video on Titanium frames to my buddy in the UK....can't wait for my friends head to explode when he watches that, lol.
The newest video on the Canyon problems was fascinating too.

In my world, expertise still matters -- especially when it comes to highly technical (scientific) topics. I'm not qualified to judge the veracity of this guy's statements (and I'll bet most bf'ers aren't qualified), and so it is all the more important that an analyst's qualifications be vetted...Which is something that we can all do.
I hope people have learned, especially in this past year, to leave science to the scientists. If we start trusting the amateurs, we'll be doing crazy things like injecting bleach.

He did make a statement I'd like to know more about. He claimed that Toray gives a value for the strength/rigidity (I can't remember the exact quality) of CF as a material. But, he added, 40% of an actual frame is the bonding agent and so that value does not equate directly to a frame value.

From a site called "poddtoppen"........."A legendary former pro, multiple TdF stage winner and ex-British Champ described him to us as 'cycling's man of the moment' and we couldn't describe him any better. Dan Bigham is the founder of trade team Huub Watt Bike and the aero accessory company Watt Shop. He is one of the fastest pursuit and team pursuiters in the world. He was due to be going with his team to Bolivia to take on a number of work records at altitude. A disruptive thinker, utilising his engineering background to re-think the art of time trialling with changes that have spread throughout the cycling world. He also consults with some of the biggest teams - Danish Team Persuit, Canyon Sram, Jumbo Visma and works with the likes of Wout van Aert.
As if today's guest isn't enough, we were also joined by YouTube sensation, engineer and self-confessed aero geek Alex Thomas, whose YouTube channel – Peak Torque – is well worth checking out."
Apparently he's some kind of engineer.

I think disc brakes are better...oh wait, I thought we were still arguing about rim vs disc brakes. Carry on.

Is there a materials scientist in the house? I always find critiques of these types of videos to be of higher value when made by someone with a background in the subject. If you have that kind of background I'd welcome your comments. I'm interested in the subject but it is not my area of expertise so I won't be making judgements.

I have no fancy math behind this, but honestly having ridden bikes made of aluminum, steel, titanium, and carbon fiber, I think the truth is all of these are viable frame materials. And I expect ride "feel" depends more on geometry and especially wheels/tires/tire pressure rather than the actual frame material.

Deliciously ironic.
On a forum noted for its endless amount of amateurs having spirited and technical discussions covering every single bicycle part and every aspect of cycling, there are all of a sudden so many fact checking credential seekers when it comes to anything negative said about CF.

We do a little CF work here and I’m involved in the design and testing. I ran the numbers once on a beam and they were spot on for calculating the deflection. Also told me we were using 3x the required resin, squeezing out resin is hard, but it’s really not rocket surgery.

But the best part is that they lay up a trial frame, build it out, and give it to the factory test rider or riders, like pilots. They report on the feel of the bike, which can then be altered for the next trial frame, etc. Thus the factory can tune the feel of the frame precisely to match the market for that frame model. That's huge. No guessing.
Didn't watch the video, but if it's not mentioned . . . there is no bike frame material which is the equal of epoxy/carbon for fatigue resistance. Maybe wood, but nothing else. OTOH, there's nothing quite as sensitive to notching and point impacts.

I think anyone should be leery of a person on youtube, earning money from clicks, who passes himself off as an "expert" in a highly technical field without offering anything that we might find on a cv. Materials Science and engineering is not something that is just picked up "on the street."
