If steel is the ultimate noble metal, titanium must be considered to be the king of metals. The titanium frame is a product, which goes beyond fashions. It is a frame destined for genuine purists of top-of- the range racing cycles and lovers of unique objects such as a De Rosa titanium frame. Clearly there are different degrees of titanium, varying in terms of their quality, characteristics and price, and a number of alloys, which are very different from one another. The peculiarities of titanium are well known: we are indeed talking about a unique metal, which offers practically unlimited resistance to wear an excellent relationship between specific weight and performance and a very high elastic modulus. In contrast the hardness of titanium does not facilitate the task of the manufacturer and perhaps because of this many other frame manufacturers concentrate on different materials.
