I Believe the older Blackburn Rack will work fine. I have 2 similar racks, and have used them extensively for loaded touring. I also use the Ortlieb Classic Backrollers. While I have not used the blackrollers on the older racks, I have used them on the Blackburn EX-1 rack. I just went out and compared the older rack with the E X-1, and the shape is almost exactly the same. The EX-1 has a little heavier tubing, otherwise they are essentially the same rack. The vintage rack has 8mm rod and the EX-1 has 9mm. I also took one of my Ortlieb rear panniers and mounted it on the older rack. While I did not make all the fine adjustments, it seemed like they would go on just fine.

Same rack on vintage bike that I am restoring.


Same rack modified to fit on my mountain bike. I welded the two plates in so that I could use the rack mounting points on the seat stays. I did leave the center support for use on road type bikes. That set up has hauled a lot of groceries. Probably more weight than I tour with



PS After looking a little closer, you actually have a newer version of the Blackburn rack. Same shape, just a newer model. It will make a fine touring rig. Your rack looks like it might have the heavier tubing.
