When my friends were planning our tour, we utilized this forum a great deal and the advice was very welcome on all counts. Now that we’ve been out a couple months, I’d like to make a contribution that might reciprocate. We have had 4 Ortlieb panniers (of 7 pairs) fail for different reasons: broken clasp, split seam, screws that come loose (we should probably own that because didn’t know they needed frequent checking). 3 were Sport Rollers, 1 was a Back Roller.
I know they are universally loved but I wondered if there were production changes and/or quality control changes (covid?).
