Surly Bill Trailer with attachment.
Time to sell. It deserves more use than what it is seeing with me. I have used it scarcely. Some surface rust there that I’ve covered with rust inhibitor since the photos. It has axle mounts for QR in boost and non boost. I’ve included some axle inserts as well. Also has the frame mounts that go directly onto selected Surly frames. The bolt comes out of these and they go straight onto bmx style wheels as well. When I had it on my gravel bike the QR axle ran through the middle of the thru axle
