Hmm, all components benefit from volume of production. WRT technology - you heard of a thing called Moores law? Technology falls in price not goes up. Processors memory hard drives screens etc. This isn't my theory, its whats driven the whole tech bubble. Its why your phone has an OLED screen which was super rare 5 years ago but is now commodity owing to volume and advancement in production.
Also carbon fab which 20 years ago was ridiculously expensive and and bespoke is now run of the mill in manufacturing and simple enough to do. 99% of frames come from Taiwan from a number of volume contract manufacturers. Yes even your high end Specialized etc. they turn them out cheap as chips and in huge volumes compared to how rare they were when they firts came to market. And they are so much better and so many more options base don types of layup, types of carbon used whereas previously there was only one version. Carbon was super rare and expnsive now its cheap as chips and available off Alibaba
SO FWIW from where I amd sitting everything seems to show me the cost of making anything like frames or group sets has fallen massively. Especially things like Di 2 where the battery tech has improved massively and carbon frames etc. The first ones were stupidly expensive and complex. Now electronic shifting has filtered down to 105 and SLX which is really workmanlike. But the prices of an XTR or Dura Ace DI 2 12 speed groupo went to R 75k? When the previous price was R 35k and lesser. A 12 speed gold anodised cluster fro Sram for R 15k? You are pulling the piss. the price bears no relation to input costs.
On another topic " Agreed marginal gains are important for pros just like hybrid turbo formula 1 cars with slick tyres and aerodynamics are important to win the Formula 1 world championship and the tech eventually blooded in racing filters down but the tech used in high tech fields like racing is really light years away from what Joe cyclist needs to get him up a hill quicker locally. Your average dude needs less rigid carbon layup than the top end pros cause he isn't as fit and as flexible and doesn't need every ounce of power, rather he needs to arrive feeling a little fresher to do it all again the next day. Whats good for a pro isn't good for 95% of cyclists - its like your average experienced racing driver couldn't even do a lap in a Formula 1 (i know its a little different but the example proves the point. ) What you race is so fine line Specializeds and pros are so stupidly fit and strong the average dude doesn't come close. Greg Minaars Santa Cruz V10 is likely unrideable for 95% of the cycling populace.
So to summarise - prices of making the stuff has definitely come down lots and the manufacturing volumes have gone up massively so the costs per unit have fallen. But the price of bikes has risen, cause the cost inputs aren't what matters anymore.
And on the other topic i replied already - supply chain collaboration is about as open as it gets in cycling. You think all the pieces on the bike come from one factory ?
Maybe we are discussing apples and pears but i think i am 100% seeing things you are saying from the opposite side, so agree to differ.
