Subframes...Round or Square?

Square sub frames are better cause the 90 degree angls at the corners replicate the triangle wich is the strongest geometrical
figure.

The more expensive bicycles use square tube on the main bar to add strength and take out flexibility.

Roll cages are a safety device thats why they use round tubing the smooth round wall of round tubing is much safer than square tubing square tubing has sharp 90 degree angles that would be dangerous in a roll over.

I use to be a welder and I am very good at it I have fabricated many metal structures.
Trust me square tube is much stronger and much better it is the angles of the square tube that give it the strength.

THE ONLY REASON PEOPLE SELL THE TUBE SUB FRAMES IS CAUSE THEY ARE SO EASY TO MASS PRODUCE.
