I do not want to take anything away from Berk either but ask yourself, he has built 4 maybe 5 frames? Berk is definitely a very talented young man. Super thoughtful and I like him a lot. There just simply isn't enough production, testing and data points to validate the work as an end all benchmark.
I just handed carbon crumpton #390(over a 9.5 year period) to my painter the other day. I am 47 years old and still do not know what I do not know. But I know as a single entity, repetition and volume brings experience. I'll get there some day.
The tolerances on some of the modern engines and various other parts (especially drivetrain) are on the aeronautical level.
and being grounded regularly these days apparently
What makes you think that tolerances used when manufacturing a bike are any different to those when manufacturing parts for a car?
Berk can design and produce a top frame himself without any serious RD or budget or engineers support team and he's like 18 years old
Not taking anything away from Berk, but are you trying to say that his frame is at the absolute cutting edge and all those known brand manufacturers are wasting their time (and multi million pound budgets) in development? For that matter, what is it about Berks frame that appeals to you? Have you ridden it?
For the record, our special projects engineer built his own time trial frame, fork and wheel set including deep rim front and tri spoke rear, all in carbon, back in the mid nineties, almost twenty years ago. I'm sure that he'd tell you that he could have done a lot more with a multi million pound budget
