As someone that has a $11k bike I can clarify some things.
I have a Wilier Granturismo SLR. About ~90% of the components are carbon fiber. Carbon Fiber, especially high end carbon fiber isn’t cheap. Besides the bike; my wheels, pedals, parts of the cranks, handlebars, saddle, saddle post, and probably some other things are carbon fiber.
I always hear people talk about getting carbon fiber components for cheaper because you have a shit tin of Chinese companies come in and steal these bike companies IP and make shit frames. Look at Chinorellos, shit ton of Chinese companies steal frame designs and re-make them with shit metal and the bike falls apart after a year.
Another thing…why does any give a fuck how much my bike costs? My dad is an audiophile guy and my bike costs as much as 1 (not a pair) of his speakers, and he has a mid-range system. Cycling is something that I love, I ride almost everyday and will spend hours and hours on the bike. I’d gladly pay less than $11k on my next bike but when you get into the higher end market you’re going to pay more, that’s true across almost ALL sports or hobby activities
