<p>1. A control device for two derailleurs, respectively for the free wheel and the crank gear for a cycle or the like, comprising two actuating elements (16, 21) rotatively mounted on a support (10) and respectively connected to one of the two derailleurs through a transmission cable (C1 , C2 ) and a lever (11) constituting a shifting element for the two actuating elements, the latter being connected to each other by a connecting mechanism (12, 18, 23, 27 ; 12, 18, 42, 43) having a travel including a lost-motion part, characterized in that the lever is fixed to the actuating element of the free-wheel derailleur and the lost-motion connection is such that the driving of the actuating element associated with the crank gear derailleur occurs for two different positions of the shifting lever, depending on whether the latter is shifted in one direction or the other.</p> |
