Howdy, y'all.

I've built a few practice frames, and now I'm ready to try my first "real" frame. I want to build a loaded touring frame. I want this frame to be stiff and stout. I'm 6'2" and 190 lbs and I want to occasionally carry a full load over dirt roads and bad pavement.

From what I've read, I think most older touring frames were made from traditional diameter 1/.7/1 tubesets. Modern touring frames are mostly oversized tubing, but again the walls are likely 1/.7/1 or maybe even thicker.

Where can I buy tubes this thick? The suppliers I know about only sell .9/.6/.9 and thinner.

And why bother with such thick walls, wouldn't it be easier to bump up to double oversized instead? I don't see many double oversized touring frames out there, so what am I missing?
