ヒップアングルを維持(BB周りに前転)すればパワーは維持できるかもしれないが，後ろに乗って前傾(サブリスキー型)した方が空力的には有利．前傾してもパワーが出る人と出なくなる人がいるから，一概には言えず，パワー/CdAレシオが重要，らしい．

(2) Landisポジションは世界的に議論の的

I was in the tunnel with him in March and all I can say is that I'm not exactly sure why, but it definitely does work.We tried the same position on Santiago Botero as well as Miguel Perdiguero and it was terrible for both of them, but with Floyd it works quite well. I think that Floyd has a different body shape than a guy like Zabriskie and he also has very large hands, but overall I think your theory on the airflow going around instead of under the body is probably pretty accurate.

風洞実験で，なぜかLandisにだけ効果があったらしい．UCIのスーパーマンポジション規制絡みもあるのかな?
