mount my auxiliary fuel tank. The tank held almost ten liters which, at about 1.5
pounds / liter, totals about 15 pounds.
I believe the rack capacity is 11 pounds. I
think engineers generally consider the working load to be 50% of breaking load. So,
while I was overloaded, I would not think that 4 pounds is that much for the size of
steel tubing used for the rack. The rack finally failed at some point riding through
a construction zone. Not terribly bad and typical of what most riders expect to
experience a few times each year.
In looking at the breaks, I noted the following:
Rust has formed on both sides. That tells me that they both cracked some time
You can also see that the tubing appears to have snapped. I would have expected
something more like the sort of bending normally required to break a piece of normal
Both breaks occurred right behind the welded on cross brace. I'm no
metallurgist but my guess is that the welding tempered the tubing and it became quite
