  competitive cycling doesn't let racers use whatever setup they want for their bikes. if something is too good, like the really aerodynamic handlebars, they won't be allowed

    Aero is quite regulated. So you can't play with wheel size, or various non-traditional bike designs. But other things seem like fair game, tweaks to geometry, different bearing technologies, new bearing races, electric shifting, disc brakes, etc. The spirit of racing is that the race should be won largely by the best bicyclist, not the best bicycle. I'd expect a more efficient transmission would certainly be considered.

      Disc brakes were also banned for pretty long.

        Right, but aren't now. Progress is being made, fortunately mountain bikers (and their organizations) are much more open to progress.

  Or at least tested by a well known 3rd party. There's been quite a bit of research on bicycle efficiency, if this worked I'd expect it to be big news in various bike research related circles. For now I'm quite dubious, especially the claim that it gets more efficient the faster you go.
