Dedacciai T6 Energy to be exact. I have a bicycle with these tubes and I can't seem to find much information on them other than the fact that they're triple butted, stiff, and the frames were used by a number of "Italian" companies (they have triangular shaped top/down tubes). How does it compare to the CAAD9's of today? Is the material more brittle, less resistant to fatigue, or generally not as good as the new stuff that's out?

Ha! Don't expect much response, coz I've started a couple of similar threads on here after I bought my Ciocc made with the same stuff, and got nothin. You'll get more from Google, like this (there's only a little info on each link):

I'd say, due to it's kinda chunky weight (my 58cm, non-sloping frame is 1560g) and rigidity, it's more on the durable and fatigue resistant side.

Also, as far as comparing it to modern stuff, I suspect the 'new' Dedacciai 7003 Light Alloy is just T6 Energy re-badged, because it has the exact same specs as mention in the old Bringheli link (above), which is: "7003-T6 alloys whose breaking points easily reach 470 N/mm2, and which posses a surface hardness of 135 HV after aging and heat treatments"

Anyhoo, my Ciocc is as stiff as bricks, and my favourite race bike. I prefer it slightly over my alu Soloist

That's pretty much what I found, but nothing from a consumers point of view. I haven't logged enough miles to really say anything about it other than the power transfer is greater than any steel frame I've ridden. Usually I feel like I'm raping the frame when I dial it up, but this frame just takes it

What brand frame is it?
