ABSTRACT:
An improved bicycle derailleur mechanism generally includes a bracket with two parallel spaced lugs extending perpendicularly therefrom, obliquely positioned on a first pivot member so that an inner cable extending through an adjuster nipple to a cable clamp on a parallelogram body is retained at a same angle when tension in the cable is adjusted by rotating the adjuster nipple, resulting in alignment between the derailleur mechanism and sprockets on a bicycle rear wheel remaining unchanged.
