I have a Topeak rack, not that one but similar.
I have Trans-it panniers from Performance. Dont recommend them but they worked fine with the Topeak rack. The rack is definitely designed to support non Topeak bags. The rack is on a Cannondale urban bike and has performed marvelously.
I plan on getting new Ortliebs, probably from REI, when the spring inventory comes in. Ortliebs are highly recommended.
Arkel makes some sweet bags – but it seems like no one has them in inventory. I am not spending that much money on a bag that I dont get to try on for size first.
I have a Topeak Trunk which I love for weekend riding. Easy on and off, enough room for a few minor things.
