I have looked everywhere for the Geo chart for this frame. Where can I find it?

How does 6061 tubing feel when it is drawn into diameters this small across the bike? I thought most manufacturers went with oversized alu tubes to keep the strength-to-weight ratio in a safe zone for riders. Are these thick-walled tubes? I'm not a metallurgist, so forgive my lack of understanding.

Normaly, if the alloy tube is round tube, the strength is not strong enough. But we use trapezium tube with hydraulic shaped two reinforce ribs on the both shoulder, and then double butted to make center part thinner to low the weight. These treatment makes the strength much stronger than the round tube. We test the frame under EN14764 standard, and it passed the test without problem. Also if you can check the other photos that showes the rear triangle tube, we use triangle butted tube instead of the round tube, with the same method, it is light but high stiffness to let the pedal power transfer to rear wheel quickly and directly. The seat tube is 31.8x1.5T and tapered on the top to 29.8x1.4T which can fit the normal steel frame's seat clamp size:30mm. If you want the CAD drawing, I can share with you by e-mail. Thanks for your kind attention!
