Thru-Skew Trailer Hitch Adapter

Our Trek Thru-Skew hitch adapter for towing kid trailers, dog 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 Hitch Adapter helps trailer hitches fit more bikes. It easily clears hooded dropouts and other interfering dropouts. It is easy to install. Simply replace the existing non-driveside nut with our adapter, and attach the hitch that came with your trailer.

Our hitch adapter uses a 17 mm wrench to attach your hitch and precious cargo more securely than with other knurled adapters. When installing the hitch, the 5 mm wrench isolates and protects dropouts from marring and over-tightening that could ruin your bike's frame.

If your bike has a 12mm thru axle we make thru axle adapters that you can find by using our Axle Finder here.

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.
