We offer thru axles compatible with BOB Trailers, the original inspiration behind The Robert Axle Project. Longtime BOB Trailer enthusiasts since 1999, we enjoy using our trailers for bike tours, trail work, and errands. Modern bikes often feature 12mm thru axles for rear wheel attachment, enhancing ride quality with increased strength, safety, and rigidity. When we discovered our BOB trailers didn’t fit our latest mountain bikes, we engineered a solution ourselves—thus launching The Robert Axle Project.

Robert Axles for BOB Trailers are precisely designed to connect your trusted BOB Trailer to bikes with thru-axles. Select the correct thru-axle for your bike using our Axle Finder. Simply transfer the “bobbins” from your original BOB quick release onto the Robert Axle, attach your trailer, and you’re ready to ride.

Topeak trailers:
Sorry, we don’t have a solution for the Topeak trailer. It is a unique connection system and we just haven’t seen enough of them to warrant a production run of multiple sizes of axles.

Burly CoHo trailers:
We do not make axles for Burley COHO trailers.
