Looks like something designed to measure force at the pedals or shoes as well as *maybe* the handlebars. I've slowed the video down a lot and there seems to be some devices near the pedals and a cable running to the bars, but there is no head unit to be seen. My guess is that maybe the bars have strain gauges in them.
The cord that looks to be attached to the SRM head unit actually isn't. It's just taped to the seapost and happens to sit near the SRM head unit on the way to the handlebars.
