I created these fat bike adapters for my old Thule racks two years ago. I’ve since bought racks that will take a fat bike naturally, and would like to pass these on to anyone wanting to try a fat bike, or who has yet to upgrade their rack. Just some plastic sewer pipe with an end cap glued on and cut to fit. Available in Halifax area.
Thanks! It worked pretty well, though I think the inside of the pipe could be roughened up or have a little rubber coating added for more grip on the tire; but that’s likely me being a perfectionist. Also recommend reusable zip ties for attaching it to the rack.
