Why do some people prefer a particular material? Carbon fibre seems to be the most popular. For me I think it is the quality of the components, and the lack of weight of a nice bike that makes the difference. I ride a aluminium bike as a run-around, and my decent bike is a carbon fibre. Cant really say if there is any advantage between the 2 materials beyond weight. Never tried any other materials. Do these frame materials actually offer tangible qualities over an equivalent specced bike?
