Re: Tube vs. Square bumpers
The romans used arches because they allowed the openings to carry more weight..
Theoretically speaking a tube is a big log archway, abutted to another big long arch.
Structually speaking the tube should be stronger (round tube)
Personally I like the look of a square tube bumper so that's what I went with.
When your talking about a fender bender, either will work and leave you with possibly a scratch on the bumper.
Talking about a head on at 40mph? well, both are going to be mangled beyond recognition.
So really there is very little structural advantage of round over square.
As fiir "sliders" I assume your talking rocker pannels.
From my experiance on the trails, the guys with the nerf bars (round tube) get hung up on stuff while the guys with the rocker pannels (1/4" angle iorn bolted to the sheet-metal) can slide over rocks.
