I have a set of C2 clip areo bars and want to route my cable through the pipes to clean up the cables. I notice there is an opening at the grips but the only exit I see is under the arm pads. It's not the most direct line to the bike frame. Anyone run their cables in these aero bars? I'm concidering drilling an opening for a more direct line to my frame but thought I'd throw out this question to see what others have done. Much apreciated.
