Abstract

L'INVENTION PERMET AU CYCLISTE D'AGIR PAR UN SEUL ET MEME LEVIER SUR LE CHANGEMENT DE VITESSES ET SUR SON DERAILLEUR. A CET EFFET, CE LEVIER UNIQUE 14 EST MONTE SUR UNE ROTULE CONSTITUEE PAR UN ANNEAU FLEXIBLE 24 MONTE SUR UN MANCHON 17 PORTE PAR L'AXE FIXE 1 ENTRE DEUX RONDELLES 15 ET 18 QUI NE PEUVENT TOURNER ET CONTRE LESQUELLES LES DEUX DISQUES PORTE-CABLE 6 ET 19 SONT REPOUSSES SOUS L'EFFET DE LA COMPRESSION EXERCEE PAR L'ECROU 21, DE TELLE SORTE QUE LE LEVIER PEUT TOURNER AUTOUR DE SA ROTULE ET BASCULER A TOUR DE ROLE VERS L'UN DE CES DISQUES POUR EMBRAYER AVEC LUI AFIN DE POUVOIR LE FAIRE TOURNER SANS ACTION SUR L'AUTRE DISQUE. CE MECANISME PERMET D'ALLEGER ET DE SIMPLIFIER LES CYCLES DE COMPETITION.
