But I can see how polymers can make a break into the market as racing bikes, provided they can provide the right weight and flex that riders prefer.


btw. I think there is a push to putting more polymeric materials into automobiles these days. Some metal parts only need to be so strong, but they carry extra weight. Getting rid of these metal parts and replacing them with plastic helps shave off gas consumption, and bring up that mpg.
