I apologize for being lazy and not going back and seeing your last post in July and speculating like I did. That was not right. I waited a long time for updates and yes, I did buy a used rack that may have been overloaded by the original owner. Not sure what production run it was but I had a certified welder fix a few stress cracks. But after a few more rides with light loads ( 10-15 lbs) , I had to take it back in again and it was frustrating. I think the second time was the charm and if your interested, I will be more than happy to share with you off-line what I think could be done to improve the load distribution and prevent flexing. And, ...I still really love the rack.
