An apparatus and accompanying method are disclosed for a handgrip based gear - shifting mechanism used to manipulate the front and rear derailleur cables o n a vehicle having a multi-sprocket gear system. The gear-shifter comprises a substantially hollow handgrip member (16) that has first and second cam guid e paths (22) in the bore of its substantially cylindrical surface. First and second cam followers (26), preferably located inside the bore of the handgri p member (16), engage the first and second cam guide paths (22) respectively. The first and second cam followers (26) are coupled to the front and rear derailleur cables (14), such that a single rotation of the handgrip (16) simultaneously adjusts the positions of the first and second cam followers (26) and the front and rear derailleur cables (14). |
