Need help with Ortlieb Backroller pannier
 

My bike's back rack has very thick tubes (Globe Haul), and the mount at the bottom of the pannier won't fit around the tube. I was thinking of adding some kind of spacer. Anybody else have this problem? Any advice?

Ortlieb makes an over-sized lower hook:
