Thru Axles for Cargo Racks

Yes, we support cargo racks that attach to the center of the wheel. Our BOB Trailer Axles work with Old Man Mountain cargo racks, Blackburn Outpost and Local racks, as well as others with adjustable lower mounting hardware. Our cargo rack thru axles may not be compatible with all racks because the thru axle is a lower mounting point than traditional eyelets and could cause tire clearance issues. To know if your rack will fit it is best to hold it in place on the bike as if mounting to the cargo rack thru axle and check for interference with your tires. There should be ample room for mud and debris to clear the rack. To purchase an axle to work with one of these racks, use our Axle Finder for “BOB Trailer Axle” and input your bike information.

See the photos below of how the Blackburn lower rack dropouts nests over our cargo rack thru axle ends. Note, we only supply the axle, not the rack dropouts which are unique to the specific rack manufacturers. We make no claim that we fit any rack, only these specific brands.
