One of Team Garmin-Transitions’ sponsors, 3T, made Cameron Meyer a special handlebar for his defense in the points race. It apparently helped! VeloNews has this report:

Garmin-Transitions rider Cam Meyer will be racing the track world championships for Australia on a distinctively shaped new handlebar from 3T.
The Sphinx is a UCI-friendly bar with a flat, aero top section and bends that raise up before curving down. In between the end of the hooks and the bends, the bars feature unique, thin, aero profiles.
3T developed the Sphinx — named after the flat-forearm position of points racers — with Meyer.
“We know Cameron through Team Garmin-Transitions,” said 3T technical director Richard McAinsh.
“He came to us and explained how he rides the points race, alternating between level high speed and all-out sprinting. We saw the chance to use a new UCI-compliant aerofoil we were developing.”
With the raised bends, a rider can somewhat mimic a road position where the wrists are on the tops and the hands are on the lever hoods. While the flat tops are not uncommon on road bars these days, the thin aero sections on the drop are very much track-specific.
