i found theres some ortlieb rear basket removeable bracket but its never in stock. I'm thinking of just attaching it with a permanent bracket. any ideas as to how to do that? I am planning on mounting the basket on a tubus locc rack. like this one Tubus Locc Rear Cycle Rack for 26in Wheels
it looks like some long u bolts with a flat bar with two holes in it for the bolt ends to pass thru and have nuts on the ends of them would work.
