Thru Axles for Cargo Racks

Yes, we do support certain cargo rack systems that attach to the center of the wheel. Our BOB Trailer Axles work with Old Man Mountain cargo racks and Blackburn Outpost and Local racks with adjustable lower mounting hardware. To purchase an axle to work with one of these racks, use our Axle Finder for “BOB Trailer Axle” and input your bike information.

With either of the racks listed above you will need to flip the mounting hardware so the 10 mm holes on the hardware nest over our BOB Axle Ends. See the photos below of how the Blackburn lower rack hardware nests over the ends.

Currently we only support mounting of rear cargo racks at this time.blackburn rack with robert axle
