Abstract

L'invention concerne un procédé de contrôle de l'intégrité d'un cadre de bicyclette (1) après un accident. À cette fin, des valeurs caractéristiques de rigidité du cadre de bicyclette (1) au moment où il est neuf en sortie d'usine sont utilisées comme valeurs de référence, les valeurs caractéristiques de rigidité du cadre de bicyclette (1) après l'accident sont déterminées selon la même méthode que les valeurs de référence et les valeurs caractéristiques de rigidité déterminées après l'accident sont comparées aux valeurs de référence correspondantes. Selon l'invention, les valeurs de référence sont obtenues par le biais d'un support de mémorisation (7) électronique et/ou magnétique qui est monté sur le cadre de bicyclette (1) et sur lequel sont enregistrées les valeurs de référence.
