Here is something I don't understand, so please help me.
I have bike with an EBB and out of the factory, wires were routed internally to the BB shell, then they come out and run to the gearhub/brake outside.
Yet, there are holes in the BB shell, so i would say, that the designers thought about fully internally routed cables, otherwise they wouldn't have put holes on the ebb shell.
But how would this work?
The way I see, my cables would get crushed if I tension the chain (after upgrade belt).
How would it be possible to route multiple cables (I am thinking on installing a di2 system) from the seat tube (battery), down tube (junction a) and to the chainstay (grarhub) and being able to adjust the tension without crusing the cables? Or why are there holes?
