When I bought my 2010 990 Adventure (used) it came with a pannier frame (quick detach) and a new set of black Gobi panniers, still in their shipping boxes. The previous owner had even purchased some drain valves to drain liquid from the Gobis. I plan a few trips this summer, and am seriously considering taking a few liters of water in the Gobis - nothing like plastic flavoured water to quench your thirst after a long ride! The Gobis however have nothing but two small press-in plugs on the front and rear for filling / letting air out, and these two plugs are not the easiest to remove or re-install. I realize these panniers are not perfect, and have many critics, but they are what I have and I don't plan to spend $$ if I don't need to. I have spent some time searching for a replacement for these plugs to facilitate filling the panniers with liquid, but so far no success. I would welcome feedback from anyone who has come up with a better solution for filling these. Cheers.
