Having watched some American Chopper (not quite bicycles, granted), I've noticed that this is how they route most of their cables: through the inside of the frame. Would there be structural problems with that sort of thing?
You could but you'd have to go through the stem cap, down the steer tube, into a fork leg and then out at the proper place. And, you'd have to put the cable back together once you are done. Seems like a lot of work, not to mention having to explain the holes you drilled in the fork to the sales rep when something breaks.
Why not just go wireless? I'm too cheap to go that route. I have up to 6 bikes I'd have to retrofit and wireless isn't cheap!
