Ortlieb Back Roller pannier on the Tubus Logo Evo Rack on my Catrike 700 "Red.
The pannier mounts low and towards the rear on the Tubus Rack.
The welded tab at the rear of the rack prevents the pannier from sliding back.
The pannier is clear of the derailleur.
(The derailleur is fully retracted as the chain is not connected).
The inward camber of the rack at the top keeps the pannier load closer to the center of the trike.
Better shot of the camber on the Tubus rack. As I mentioned in my last post the Tubus does not work well with conventional trunk bags because of the narrow top platform.
This is how to eliminate the trunk bag and pile on the load.
