anyway, what you said about benefits of certain properties being better suited to certain parts of the bike and other properties being better suited for others... you're absolutely right. which is why a composite is infinitely better than basically anything else. you can control what properties the material takes on. you can control in which orientation you want flexibility vs strength. you can use different epoxies or mix in different additives to achieve different material properties. that's not a thing for other mono-materials. unless you are a foundry that produces your own metal mixtures (hint- no frame builder does this), CF is the only method to actually achieve these changes. the only way to achieve such a thing with non-composites is structurally. literally making parts thicker or thinner. which isn't an easy thing to do. you wind up making these stupid compromises like butted tubes which have their own host of issues that have to be overcome. these days what does your average frame builder do? they buy pre-butted tubes. they don't take the risk of ****ing it up. because they WILL **** it up.
are there other issues with cf layup? absolutely. but the potential "best" in a composite is far better than what can be done with a single material. why else do you think they are all carbon now?
