Robert Axle Project Adapter for QR Hitch

The Robert Axle Project Quick Release Hitch Adapter is for bikes with 5mm quick release rear axles. Our hitch adapter for towing kid trailers and single-arm bike trailers is high quality and precisely machined. This includes all the two-wheeled child, pet and cargo trailers such as: Thule, Chariot, Burley, Instep, Carry Freedom, and many more.

Our hitch adapter is made of stainless steel and is incredibly durable. It’s built to handle towing a fully loaded bike trailer. The Robert Axle Project Quick Release Hitch Adapter helps trailer hitches fit more bikes. It easily clears hooded dropouts and other interfering dropouts. It is easy to install. Simply flip the quick release, replace the QR nut, and attach the hitch that came with your trailer.

Our hitch adapter uses a 5mm hex to attach your hitch and precious cargo more securely than with other knurled adapters. When installing the hitch, the 5mm hex isolates and protects dropouts from marring and over-tightening of the quick release.

At Robert Axle Project we believe in enhancing the role of bikes in your life’s adventures. Expanding our immensely thorough catalog of thru axles for trailers, racks, trainers, and more, helps us do that.
