A bicycle transmission system, comprising: a self-indexing derailleur (1); a cable (4); and a controller (2) coupled with derailleur via the cable, the controller comprising: a first rotatable member having the cable at least partially looped around a perimeter thereof, wherein a resting position of the first rotatable member is controlled by indexing at the derailleur; and at least one user-engageable lever mechanically coupled to the first rotatable member such that actuation of the at least one lever imposes a rotation on the first rotatable member, which, in turn, imposes motion on the cable to shift the derailleur, and a corresponding derailleur controller for use in connection with the bicycle transmission system.
