<p>The invention concerns a system enabling by means of a pulley (1) winding a cable (4) with anchoring head (13) to actuate in particular a cycle derailleur. A sheath (40) reacts to the action of the cable (4) with its cable stop (21) housed in a cable housing stop (2). Said cable housing stop (2) is subjected by the external contact of the pulley (1) equipped with notches or cam(s) to reciprocating movements in a radial (or almost radial axis), preferably in the axis (B) of its fixing means (3) with the support (5). In the event that the fixing means (3) passes through the pulley (1), a slot (11) forming an axial and retaining stop (A) is arranged in said pulley (1). The sliding cable housing stop on the axis (B) provides, among other things, a speed indexing. The invention is particular designed for the cycle equipped with a rear and/or front derailleur.</p> |
