Can you build a reliable 7005 alu frame without post-weld heat treatment? Brant mentioned 85%(I take it that means percentage of potential strength, correct me if I’m wrong though…). Would that make a safe, reliable ridable frame?
Also, I’m aware of the different properties of different brands/types of steel tubing because this stuff get discussed to death but does anyone have opinions on the different types of alu tubing available: 7005, 6061, Easton tubsets, Alcoa etc? if anyone knows of any good resources on the web?
