This is the frame tubing I'm considering. (I'm also working on a fork). The list is just a list of Tubing diameter, and thickness. The one thing I'm leaving out are the butt lengths. . . . What are Butt length you might ask. The tubing I'm going to use is double butted, that means the tubes are thinner in the middle then on the ends to save weight.
Now the trick is to determine how those tubes are going to flex. Henry James has a butt length chart for True Temper tubing.
I'm not really to concern myself with tweaking tubesets just yet. I'll just take the tubing kit as is because this frame will be more of an assembly exercise, than frame performance exercise.
