Unless you use the heat treated super high end tubing most butted main tubes are either .8x.5x.8 or .9x.6x.9 in thickness. A frame like the Hillborne has a slightly lighter mix of tubing than the Atlantis but heavier than the Hilsen (from the Riv site). I think Grant once wrote that the Atlantis used .9x.6x.9 dimension main tubing....regardless, it is a touring frame and suitable for loads to 275 pounds. The Hillborne previously had a load rating to about 260 and the Hilsen about 250 lbs. You don't read much about these load ratings anymore and they are pretty conservative anyway. Keep in mind that ride qualities are a blend of several elements not limited to tubing dimensions. Knowing the numbers won't really tell you much unless the other stats are the same. I have a frame building book that states 8x5x8 tubing is suitable for riders over 200 pounds and I am talking the modern outside dimension stuff here (the kind Riv bikes have) not the small diameter 1 inch etc. stuff used years ago. I'm not sure of the fork tubing dimensions on the Hillborne but I think Grant specs them to be safe enough to last for years.
