  • 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?

  • If you're tempted by the Sevens at Sigma, then go and have a look at the Serottas at CycleFit, if I had the money I'd have one for sure.

  • what you think about the white one (not shown here so far)???

    the lettering is not the best but otherwise I quite like it. Thinking of that one for myself. Not too keen on the retro look if the frame isn't really old

  • +1. More subtle. Chrome is retro.

  • BTW De Ver Cycles, Streatham do Colnagos, worth a look.

    Paduano Racing FTW.

  • Can't put my finger on it but something is definitely missing from that^

  • You're right trevor, the standard limit is a grand, but employers can apply for a special licence that costs 750quid that allows employees to spend as much as they wish.
    You lucky sod! I tried to convince my company that this was a necessary purchase. They didn't agree.
