In sport climbing, participation options and positions are negotiated based on performance. Thus, individuals are differentiated according to physical (and supposedly gender-related) abilities, knowledge bases, and motivational situations. Using a typology of actors, the author demonstrates that social order is established through movement competence and gender arrangements are made relevant—additionally or alternatively. With increasing skill, gender differentiations recede into the background. However, they are quickly reactivated as soon as people cannot (yet) explain competence differences in any other way. Gendered or genderless differentiation is rarely intentionally used for gender discrimination, but it can have such an effect.
