That, I don't know. I emailed their product support, asking for clarification as to whether the black portion replaces a standard axle nut or ...loquin, have you seen any of these styles before? Do you know if the arm bars attach to the existing rear axle threads? I guess I could call.
tech support said:Hi Lou,
The ball swivels thread into the hitch arms. The hitch pins (part E: also called secondary safety pins) pass through the eyelets into the receptacle ends (part D) that have been threaded onto the skewer (part C). That skewer should be going through your axle in place of your regular skewer. If your bike does not have quick release hubs (uses skewers), the trailer cannot be mounted to you bike.
Quick releases and spoke count have nothing to do with each other. You can get 36 hole hubs with QR's and you can put a QR axle in any nutted axle hub no matter what the spoke count, or vice versa. The nashbar trailer could be made to work with either type of axle without to much effort.That's a happy time fail. Quick release hubs are not 36 spokes. Not 36 spokes mean Happy time sprocket won't line up right. Not line up right mean spokes get loose too fast.
Spokes get too loose fast means epic fail.
They need to fix that...although it looks like someone can fabricate a fix.
It's definitely a good buy though.
