Brake having custom kinematics and wide range adjustability for wide and narrow rims

A brake for a bicycle, the brake comprising:

• a first brake arm pivotable about a first pivot axis, an upper portion of the first brake arm defining a first camming surface, a lower portion of the first brake arm being capable of receiving a first brake pad;
• a second brake arm pivotable about a second pivot axis, the second pivot axis being set at a fixed distance away from the first pivot axis, an upper portion of the second brake arm defining a second camming surface, the first and second camming surfaces having a mirror configuration of each other, a lower portion of the second brake arm being capable of receiving a second brake pad;
• a cam driver disposed between the first and second camming surfaces, the cam driver maintaining contact with the first and second camming surfaces between unactuated and actuated positions of the brake;
• a brake lever secureable to a handlebar of the bicycle for actuating the brake;
• wherein the first and second camming surfaces have a curved configuration so that a linearly increasing brake force is applied to a rim of the bicycle for each unit of displacement of the brake lever.
