Abstract
Chaîne pour bicyclette équipée d'un changement de vitesse à dérailleur. Les plaques extérieures 12 de la chaîne présentent, au moins sur leurs faces tournées vers les pignons des creusures 16 formant des cavités arrondies entre les rouleaux 13. Le passage de la chaîne d'un pignon de petit diamètre à un pignon de plus grand diamètre est facilité, première dent du grand pignon s'engageant facilement dans la cavité agrandie 15a.Bicycle chain equipped with a derailleur gear change. The outer plates 12 of the chain have, at least on their faces facing the pinions, recesses 16 forming rounded cavities between the rollers 13. The passage of the chain from a pinion of small diameter to a pinion of larger diameter is ease, first tooth of the large pinion easily engaging in the enlarged cavity 15a.
