Yeah, and extra light tubing at that! It is 1/4" diameter and I think the walls are 0.035". It was a rush build. I was being sent to Ann Arbor to collect some data for my PhD and needed/wanted to not be dependent on public transit and ride hailing apps. Found out I couldn't take my Trek because it was too heavy for the airline when in the Iron Case, so this and a decaleur went on the Vitus. Heaviest load was when I did a trip to the Kroger and came back with 3 quarts of cottage cheese, a bunch of peaches, salad greens, sausages, and two frozen pizzas all filling up/bungeed to the Berthoud bag. The rack didn't even bend. Which probably means if it ever does fail, it'll fail by cracking, not bending!
