I am guessing the low CdA is mostly due to her being skinny. Those are some toothpick legs. What impresses me is how much potential she could have (assuming the eyeball windtunnel is even close to accurate). Aero socks and better shoe/pedal choice could be 6+ watts. Long sleeve skinsuit. A little more hip rotation and better hand placement. If 0.19 is correct, then 0.175 is a possibility.

As I've mentioned, the initial CdA estimate should be taken with a pinch of salt. That said I know lots of people <.180m^2, so it's plenty achievable, especially at her size.

Is it possible she had to make some position changes to make it uci legal so she's just not properly adapted to the way it fits? Might explain why her hips aren't rolled and such.

By the way, Lisa took the silver medal in the women RR on a very hilly 15 km circuit over 120 km

Well, best one, Emma Johansson with two olympic silver, has quit so not as good as it used to be. But good work of Lisa. Just few seconds off another gold too
