Wired, yes.
Both sensors are mounted on the chainstay. Rear-wheel and crank get the magnets. I've done a pretty masterful job of taping the wire along my downtube with clear packing tape. I'm quite proud of it actually. It really does LOOK wireless except for a little sliver of extra wire by the fork. And nothing moves at all.

I am a little worried that I'll hit the sensor(s) with my huge work shoes when I wear them, but it didn't happen just now, so I may be in the clear.
