A device and method of mechanically synchronizing the displacement requirements of a bicycle derailleur with the displacement created by an indexing gear shifter lever. The device includes a linkage element that is mounted to a bicycle between a gear shifter lever and a derailleur. The linkage element is mounted to the bicycle with a pivot hinge, wherein the linkage element is free to rotate about the pivot hinge. A cable from the gear shifter lever is attached to the linkage element at a first distance from the pivot hinge. A cable from the derailleur is attached to the linkage element at a second different distance from the pivot hinge. As the cable from the gear shifter is moved, the linkage element is rotated and that movement is transferred to the cable for the derailleur in a compensated manner.
In a bicycle having a frame, a chain, multiple gears upon which the chain can ride, a gear shifter for selecting one of the multiple gears, a first length of cable moved by the gear shifter, a derailleur for physically directing the chain onto a gear selected by the shifter, and a second length of cable that leads to the derailleur, a cable displacement compensation device, comprising:
A bicycle assembly, including:
On a bicycle having a gear shifter lever that causes a first cable displacement in a cable, when shifted between consecutive gears, and a cable controlled derailleur that requires a second cable displacement in a cable to change gears, a method of coordinating the first cable displacement created by the gear shifter lever to the second cable displacement required by a derailleur to properly shift gears, said method comprising the steps of:
