ABSTRACT:
A brake lever arm is mounted to a base member, with the base member fixed to a bicycle handlebar. The lever arm is pivotal about a pivot point on the base. The lever arm includes an adjusting mechanism that adjusts the position of the lever arm when the lever arm is in a brake dis-engaged position. The adjusting mechanism is slideable in grooves in the lever arm such that the adjusting mechanisms may be moved to positions that are differing distances away from the pivot point. The adjusting mechanism includes a contact member that engages a brake cable connected to the lever arm when the lever arm is moved from the brake disengaged position toward a brake engagement position. The position of the contact member with respect to the pivot point determines the effect movement of the lever arm has on the cable. In this manner, the adjusting mechanism adjusts the length of the stroke or travel of the lever arm from the brake disengaged position to the brake engagement position.
