What is a common size tubing most people use to build their fender supports? I was thinking 1" but now that I look at it, it seems a little big to me. That means I'll have to slide it into a 1-1/4" tube on the cage/frame to secure it. Would 3/4" x .120 be better, and will it be strong enough ? I'm building a hoop in the front with 3 dzus tabs and one hoop in the rear with 4 dzus tabs.
