>>1802616>Bicycle parts breaking hardly were a thing before the advent of aluminium and carbon.It's no issue, composites require different way of thinking and different analysis, and in most cases it has no yield point. It can support loads after first fracture, especially in the case of pressure vessels, but usually you just make it strong enough that it doesn't get close to the full strength.
When you try to get lightweight racing bikes, then stuff breaks because it's supposed to. Otherwise it's not optimized. If you design a bike for a 155 lbs rider, then some 170 lbs rider rides the bike, it's supposed to break, else it was a shitty bike.
The problem is we want a bike that is super cheap, super reliable, and aesthetic, instead of 'performance' rely on the simplicity to avoid unnecessary weight. That's fine, but there's very little market for such a bike made out of composites, for road use. so it's a consumer/market thing.
