AltRider luggage rack
This is one of the most versatile luggage racks I have used. While you can strap a duffle to pretty much any rack. Not many come pre-drilled to accept other mounts that you may actually want to use. I have used mine configured with the Givi mount system I purchased from Caribou to install my Pelican case of camera gear as well as the RotoPax mount for a jerry can. Everything has been held securely for hundreds of miles over very rough roads.
All holes have lined up perfectly making for a very easy install. I’ve dealt with other brands products that typically require some amount of alteration in order to make it work. Not the case with AltRider, you really cant go wrong.
