Simone Biles Dials Up the Difficulty, ‘Because I Can’

The Olympic gold medalist’s new vault is so dangerous that gymnastics, for now, limits the scoring rewards for trying it. Biles says that’s unfair.

INDIANAPOLIS — Simone Biles, the most decorated gymnast in history, is renowned for performing moves so difficult, and so distinctive, that several have been named after her. On Saturday, she executed a new one considered so dangerous that no other women even attempt it. Her latest signature skill is called a Yurchenko double pike. Biles attempted it in competition for the first time on Saturday night at the U.S. Classic, her first competition in 18 months.
