Simone Biles’s eponymous Yurchenko double pike is performed on the vault.
The skill is officially known as the Biles II. A gymnast begins with a Yurchenko-style roundoff entry onto the springboard and vaulting table, then launches into a backward double piked salto. The skill combines a highly difficult entry with two backward rotations while the body remains piked.
Biles first competed the Yurchenko double pike at the 2021 U.S. Classic, becoming the first woman to complete it in competition. It initially received a D-score of 6.6, making it the most highly valued vault in women’s gymnastics at that time. The skill was later named after her under the sport’s tradition of honoring gymnasts who introduce new elements.
The name can cause confusion because Biles has several eponymous skills. Her Biles on balance beam is a double-twisting double-tucked dismount, while her floor skills include difficult double-layout and triple-twisting elements. The Yurchenko double pike is specifically a vault, not a floor, beam, or uneven-bars movement.
