Guess you dont' have a Klein ? Mine comes out the down tube near the bb. I had a some what unknown wrench change out my derailleur cables . Ask first if they are familiar with chaning internal cables. At this shop it took them all afternoon. I thought it would be a one hour job. I told him in advance it was internal. Still he charged me for an hour. It was his first. Not kidding you. He even once used a vacauum hose to try to suck the cable thru the housing.
