carbon rotors saves allot off weigth but other from that they are not that good,you need to reach realy high tempertures to actually work,below that you have almost no power.Carbon is also weaker and more expensive.A steel or floating rotors are stronger and better.Bikes don't need carbon rotors only racing cars like DTM,F1,Nascar and now motorcycle racing are running carbon rotors as well but they are going 300km/h.I'm not against carbon rotors but for i know they are no good for bikes eaven MX and Super moto doesn't use carbon rotors.
carbon rotors on f1 and nascar arnt made out of this sort of carbon tho either its more solid and doesnt have this patern on it, how did they work out ?
