Allow me to add to your frustration with my rant. I hate internal cable routing. It is so much of a hassle to service the cable (yes, cables can be serviced without replacement) let alone replace them. For a job that should take so short a time (lubing cables, insuring free movement), internal routing seems to add a lot of frustrating effort for so little addition to one's ride. I know that ALL my rides don't have a timing chip involved. My riding partners don't care whether i finish 10 feet ahead or behind them. To my perspective internal routing is a marketing solution for an ego problem. There, done. Andy.
