> New developments in bike design and construction have led to many > carbon fiber (ie. plastic) and aluminum bikes. They have displaced the > old standard whcih were made of metal, often called "Cro-malloy." Columbus used to make a tube set called MAX which is heavily oversized and as stiff as aluminum. > The carbon and aluminum bikes are lighter. Some are more rigid than the > steel. They climb well, but they don't descend as well. I personally think that these qualities are more related to the geometry of the bike and tubings then the materials that is used.
