Aluminum Tubing
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?
