DKL -

Are you running the 1 1/4 variant with the adapter.
This seems like the smart way to go, as it affords one mobility to swap should it even needed to go on a hitch that was smaller than 2".

I'm concerned about wobble....but the reality is, we're probably talking single bike for a good while until I get the wifey or the munchkin *who's still on a balance bike* to graduate to a bigger bike. So load weight, I'm good all around
