• So lack of air resistance would facilitate a much higher top speed, but would starting off be noticeably easier (ie could you use much higher gearing than usual). Or is that more to do with overcoming inertia?

  • The latter. Gravity only really works against you when climbing, and there's none of that in a velodrome.

    Air density is why velodromes high up in the mountains are considered "faster" than those at sea level. The minimal difference in air density does make a difference at these speeds.
