Are there any integrated bar/stems that route the cables through the stem? It seems like a longshot, but maybe an integrated bar/stem designed to work with a bike that routes cables in front of the steer tube, like many modern aero bikes are doing?

The reason I ask is that it's been reported that the Knot front end on the Cannondale SystemSix weighs 566g in 42/100 - 320g for the bars and 246g for the stem - and I'm curious if there are lighter options. I know you can run a standard stem and bars, but I wouldn't want cables sticking out - that's one of the reasons you buy an aero bike after all. Here is the Knot setup:

It's pretty darn clean, if not "perfect." The cables aren't entirely hidden the way they are, say, on a Madone. But for me, it's quite clean enough, IME with the bike, you really have to look for the cables to see them.

Here is what the ideal integrated bar/stem would look like. You wouldn't want the cables to come out the usual place (i.e. from the base of the bars ) and I've crossed that out in red. Ideally you would want the cables to come out the stem, somewhere in the vicinity of the red circle. Is there anything out there that does this?

FSA has their ASR bar coming out soon that should be a clean option for those wanting to stuff some cables and wires.

Something like this looks like a pretty interesting option, though I dunno about getting spacers to match the shape of the SystemSix head tube...
