Non-fixed-gear, but what the hell.....

What I wasnt expecting was to be dazzled by the titanium Sevens!.......I almost left a deposit on one (thats another story.....) but I restrained myself and walked away to sleep on it. But no. I'd rather the Colnago fully loaded over an entry level Seven with 105s (3000!). And titanium will eventually become a more common, easier to produce material by the time my Colnago is a lump of rust, surely? (By which time I will undoubtedly be past caring).

Titanium has an image of being a rare, hard to get, difficult to work with material. Titanium is an element, atomic number 22 on the periodic table. Titanium is the fourth most abundant metal on our planet. Titanium is most often mined as the ore rutile or ilmenite.
Titanium was not discovered until nearly 1800 and only processed into pure metal in 1910. Over the last four decades has titanium has seen significant growth as a commercial product. Titanium is abundant but difficult to refine and process. Unlike Aluminum which is economically refined using an electrical process, titanium is commercially produced by reducing titanium tetrachloride with molten magnesium. The difficulty in manufacturing structural titanium metal, not its rarity, is responsible for titanium's high cost.

  Nearly all titanium metal used for production is an alloy. Like other pure        metals, pure titanium requires the addition of other elements to achieve        the structural properties that performance applications demand. The most        common alloy in use (60% of all alloy production) is Ti 6-4, an alloy of        6% aluminum and 4% vanadium. This common titanium alloy possesses a tensile        strength of 135,000 psi. For Aerospace applications RCS uses Beta-C alloy        certified to multiple aerospace specifications.

Where's yours wayno?
