Combined gear change and brake control unit for a bicycle comprising, a support body (12) which can be fastened to the handlebar of the bicycle, a brake control lever (14) pivotally mounted on the support body (12) around a first axis (16), a gear change control unit (18) connected to the support body (12), comprising a shaft (20) turning around a second axis (22), substantially orthogonal to said first axis (16), in which the gear change unit (18) comprises a ratchet mechanism comprising a gear (26) fastended to said shaft (20) and a meshing unit (28), connected to a connecting element (36) to freely turn on said second axis (22) and a gear change lever (58) operatively associated to said ratchet mechanism (26, 28) for controlling the rotation of said shaft (20) around said second axis. Said gear change lever (58) is fastened to said connecting element (36) for the oscillation movements around said second axis (22).
