I'm building up a new frame and all is pretty much done.
When I am routing the front derailleur cable through the bottom bracket guide and then to the front derailleur, I notice that the cable is touching the back of the bottom bracket shell.
If I leave it like this and ride, I'm concerned that the cable will cut a groove on the frame (similar to a fellow BF member).
I inspected the shell and there is no hole for the cable to pass through. Is there anything I can do so that it won't damage the frame?
