I have a Diamond Hanjo gravel bike that I want to add a rack and panniers to. I bought a pair of used Arkel bikepacking panniers (28L, I think) on eBay, but the rack attachment is older than the style currently on their webpage. I'm waiting on their email reply. It seems that aluminum C-clip should spin 90deg to lock onto the top tube of the rack, right? There are so many styles of rear racks that I don't know if all panniers fit all racks, or if they have to be properly paired.
I also see racks made for disc or non-disc bikes, but my bike seems to have plenty of eyelets. Do I need to get a disc compatible rack, or do I not because I have eyelets?
And what about the front? I only see one eyelet. Maybe this is for something else like a water bottle cage and not a rack?
