Electronic & Hydraulic Shifting (Di2, Ui2, customisations)

Mmm wireless. Much hot, so want.

Is wireless braking actually a possibility for the future? Car's have fly by wire systems so maybe it's not such a ridiculous idea. Although the notion of running out of battery mid descent could be interesting.

No. No car has FBW brakes. The failure modes are horrible, there is no safe way of dealing with battery problems, and the forces involved would require enormous batteries. Not going to happen.

And so long as we still have brake cables, the benefits of wireless gears seem rather marginal to me. If you're keeping the brake cables then attaching a single electronic gear cable to one of them seems less than onerous. Probably won't stop me from getting an eRed groupset once it comes out though...
