Dedacciai D7.9 Tube & Casati M:7.9

在車展拿到Dedacciai 最新的目錄，有關新車架使用管材之原廠說明如下：

It is the Series of tubes manufactured with a Zircon-Magnesium-Scandium light alloy that ensures the best mechanical characteristics currently available on the market. In fact, with Dedacciai special process, the Series enables to manufacture the absolutely lightest cycling frames in the world The alloy employed offers technical characteristics 50% better than the typical properties of standard alloys currently used in cycling frame production. It suffices to think of its 650N/mm2 tensile strength at break, a characteristic that guarantees the manufacturing of tubes with reliability and resistance characteristics until now considered impossible.

 

Think that the future of lightweight frames is carbon, carbon and carbon? Deda would like you to think again. Like Litespeed with its 770g Ghisallo SL frame, Deda is leading the metallic fightback with its new hydroformed tubes called D 7.9 made in a special aluminium alloy that maintains rigidity yet is still light; according to Dedacciai, the tubeset weighs only 790 grams!

If you are really concerned about the extra grams, Casati offer raw brushed finish. by BiciRace .com
