I converted a Di2 frame to cable shifting. It took some time to source the proprietary cable stops and BB cable guide. The guide proved to be useless as it didn't prevent contact with the frame so I had to resort to 3D printing something more functional. The average person won't be able to deal with all the subtle incompatibilities modern bikes have.
