Title
(EN) BICYCLE DERAILLEUR CHAIN DRIVER
(FR) DISPOSITIF DE COMMANDE DE CHAÎNE DE DÉRAILLEUR DE BICYCLETTE
Abstract
(EN)
A manually controlled chain driver apparatus for a bicycle drive chain derailleur providing necessary forward chain movement for derailleur operation less power transmission to bicycle pedals during stopping and coasting instances when pedaling motion has ceased or is not possible.
(FR)
L'invention concerne un appareil de commande de chaîne à commande manuelle pour dérailleur de chaîne de transmission de bicyclette qui fournit un mouvement de chaîne avant nécessaire pour une transmission de puissance sans opération de dérailleur à des pédales de bicyclette pendant les cas d'arrêt et de marche en roue libre lorsque le mouvement de pédalage a cessé ou n'est pas possible.
