Trek had their internal routing ports incorporated into the castings. In fact the internal shaping of the castings were conical in that they guided the bare cable to the exit port. I have seen bikes with oval top tubes that had the ports at the major axis "ends" as they stuck out past the narrower ST and HT. Port reinforcements to mitigate thin wall cracking is a common element on many versions. However incorporating (love that word...) this reinforcement into the lug isn't very common. How the casing loops are routed or their "size" would be a concern of mine since I ride a small size bike and don't like tightly curved casings. Andy
