I forget who, but someone on here got a carbon CX frameset and did this exactly due to the tight bend that a compressionless housing couldn't do, he got Di2 and TRP HY/RD.
If it's rubbing I'm gonna have to design some kind of sheath.
I made one for my di2 CAAD10 out of some plastic sheeting bent into a tube. The bend causes it to push outwards away from from the spindle and keeps the cables out of harms way.
