Abstract
A front derailleur for a bicycle as well as a system including the combination of a front derailleur and shifter. The derailleur includes a fixing member securedly attached to a seat tube of a bicycle frame through a tightening band, a chain guide and a pair of linkage members for supporting the chain guide movable in reciprocation with respect to the fixing member. Further included in the front derailleur is a spool rotatably connecting the fixing member to the chain guide whereby actuation of a shifter located remotely from the derailleur results in rotation of the spool through looped cable causing pivoting of the linkage members and movement of the chain guide in reciprocation with respect to the fixing member.
