Abstract
A gear shifting system derailleur having a derailleur integrable with devices having a positionable chain, belt and/or a plurality of sprockets. The derailleur includes, a frame, a linear actuator having a housing, two bracket links and a damping element. The linear actuator includes a linearly positionable arm. The bracket links and a damping element are positioned and adapted to apply a biased force against the linearly positionable arm. The damping element is coupled with both the chain pulley and the bracket links, wherein the damping element positions the chain pulley within the derailleur as driven by the bracket links. Wireless and/or wired communications and control modules and pathways are provided to enable user control of the linearly positionable arm. The derailleur may be attached to or comprised within a vehicle, such as a bicycle, a tricycle or a vehicle with more wheels.
