Need to move front derailleur down by the most inconvenient amount
Hello folks,
I have a carbon fiber bike with one of those bolted on "braze on" derailleur mounts. The chainring is 44T and the derailleur is Shimano Ultegra R8000. Unfortunately, the derailleur needs to be moved downwards enough such that the mounting bolt runs through the metal at the end of the bracket's slot. Which means that I can't use one of those "offset the derailleur below the braze-on because that would now put it too low. In an ideal world, I could get get a different mounting bracket that's lower, but it was probably a proprietary part that comes with the frame. What are my other mounting options if I choose to stick with this derailleur? Also, yes I can make parts in the machine shop.
