I'm looking around at road bikes with a view to getting one in the next couple of months. What are people's thoughts on internally routed cables? I note Giant's new TCR, the 2012 range will likely have this feature - or maybe just the top model shown in link below?

Is it just easier to clean or are there other benefits? Should/would it be a deciding factor all else equal or just a gimmick?

It looks neater & also keeps the inner wire out of the weather (especially the cable guide under the BB) & away from snags for if the bike is parked. (I've seen cable lugs caught & ripped off frames before)
Some companies make it easy to thread the cables through with built in cable guides inside the frame, Some don't.
I built a Scott plasma time trial bike with internal di2 last week (not for me). I wanted to jump off a cliff! You need to thread the di2 cable & brake cable through the bottom bracket shell- out the head tube- THROUGH the fork steerer tube- through the stem and then through the bars. What a headache.

Although the routing through the bars and stem sounds like something I'd want not so much the tt bike though.

What an excellent idea!

But sensing the tension in and pulling on external gear cables (under the down tube) is handy when tuning the derailleurs.
The older I get, the simpler a setup I want. God help me if I ever slink to DA Di2

A vaccuum cleaner is even easier. Done several internally routed frames - all pretty easy, only the Ridley Noah needed the vaccuum cleaner. Now the concealed cables under bar tape - now that can be a HUGE pain.
