ABSTRACT:
A bicycle brake lever mechanism having a bracket mountable to a bicycle handlebar, a lever mounted for pivotal movement to the bracket and a brake cable connector connected to the lever. The cable connector is connected to the lever via an adjusting mechanism for so that the return position of the brake lever relative to a lever bracket may be adjusted to accommodate various sized hands. Further, the adjusting mechanism allows for adjustment of a lever ratio A which is defined mathematically by the distance between the pivot point of the lever and the pivot point of the cable connector on the lever divided by the distance from a set point on the brake lever to the pivot point of the lever.
