Hi, I have a Turbo Vado 5.0 IGH and use Ortleib Back-Roller panniers. The panniers fit great on the top brackets, but I am having trouble getting the lower 'arm' bracket to secure to the rack. It seems the rack is bent out away from the bike frame, so that the screw on the arm cannot tighten all the way, and comes loose when riding. I can get it to work if I retighten every day, but this isn't ideal obviously. I'm going to play around with repositioning the top brackets in hopes this changes the geometry of the bottom bracket to something that works better - but I thought I'd check here to see if anyone has had success in mounting their Back-Roller panniers. Thanks!
