I just bought a steel frame with intentions of transferring the parts of my utility bike over to it, since it's larger (utility bike is too small for me). Problem is the rear dropout area is much smaller around the QR mount area. This bike is primarily used to haul my cargo trailer, and I'd rather not have to get a different trailer. Is there any way to make this hitch work on this bike? I'm guessing a spacer wouldn't work.
