I'm looking to build another bike, a full suspension swb this time. Similar in design to an Optima Lynx, 20" front and 26" back but the main design problem for me is the back forks. I'm calling them forks because it isn't a rear triangle, just a fork.
My question is what steel should I use for the forks? My last bike I built with 1.5" square 1/10" thick tubing, it was all I could find locally and I forget how much it was but ordering in something thinner was crazy expensive. I don't want to use that tubing again because it's heavy. The frame of the bike will be 1.5" conduit, it's only the forks I'm asking about.
Here are my options:
-1" round tube with 3/32" thickness
-1.5" round tube with 1/16" thickness
-1.5" square tube with 1/10" thickness
-1" square tube with 1/10" thickness
-1.25" square tube with 1/8" thickness
-1.25" square tube with 1/10" thickness
-1"X2" rectangular tube with 1/10"thickness
That's what I can either buy locally or already have some scrap of. I can also get all the regular sizes of conduit. I'd love to use the 1" 3/32" round or 1" 1/10" square for weight reasons but I'm unsure if it would be strong enough.
Opinions?
