A bicycle brake including a first lever and a second lever is provided. A roller for mutual coupling of the first lever and second lever is pivoted to one of said first lever and second lever and is in rolling contact with a surface portion of the other between said first lever and second lever. The surface portion has a profile defined by a curve that passes by a predetermined number of points of the roller. Each of the points are defined as function of the position taken by the roller during a respective rotation of the roller about a first rotation axis (X1) of the first lever by a respective predetermined angle of rotation and about a second rotation axis (X2) of the second lever by a respective angle substantially equal to said respective predetermined angle of rotation.
