      I’ve found in the cycling world there’s is an excess in proprietary design. And functionality suffers. For instance everyone should have a pivotal seat/seat post. But BMX owns the patent

      There’s nothing wrong with the design,it’s more the bikes design were the derailleur is screwed on,doesn’t look standard.

      You’ve got to remove the optional derailleur hanger extension that comes mounted to the derailleur.

      That’s an interesting hanger or adapter, I’d point my finger at that vs blaming the RD.

      In 35 years, I came across this once. I went to Home Depot and got a carbide flat cutting router bit. I already had an X – Y axis vice. I put the derailleur hanger in the vice, locked the router bit into the drill and moved the x-y vice under the router bit milling a couple mm off the hanger till it worked.

      Check your limit screws for proper travel and then your cable tension. I usually set the limit screws to allow for about a half chain width from the centre of the top and bottom cogs.
