A control device includes a housing having a base portion and an extension portion. The base portion of the housing has an inward facing side and an outward facing side. The control device includes a lever coupled to and pivotable relative to the housing, and a master cylinder portion supported by the housing. The master cylinder portion has a hollow fluid cylinder. The control device also includes a piston assembly supported by the housing. The piston assembly is movable relative to the master cylinder portion. At least part of the piston assembly is disposed within the master cylinder portion. The master cylinder portion is angled relative to the outward facing side of the base portion of the housing, such that the first end of the fluid cylinder is closer to the outward facing side than the second end of the fluid cylinder is relative to the outward facing side.

Control device for a bicycle

A control device mountable to a handlebar of a bicycle includes a housing, a lever coupled to and pivotable relative to the housing, and a master cylinder portion supported by the housing. The master cylinder portion has a fluid cylinder. The fluid cylinder has a first end and a second end opposite the first end with a cylindrical wall therebetween. An opening extends through the master cylinder portion, from the first end to the second end. The control device also includes a plug removably connected to the master cylinder portion via the opening at the first end of the fluid cylinder, and a piston assembly supported by the housing. The piston assembly is movable relative to the master cylinder portion. The housing is made of a first material, and the master cylinder portion is made of a second material. The second material is different than the first material.

A hydraulic brake control device for a bicycle includes a housing having a first side and a second side, the second side being opposite the first side. The housing includes a first hydraulic line path and a second hydraulic line path, the first hydraulic line path including a first recess at the first side of the housing and the second hydraulic line path including a second recess at the second side of the housing.

Dual-sided brake controller housing

A bicycle control device for use with a road bicycle includes a hydraulic brake control device and also may include a shift control device. The brake and shift control devices are disposed within a housing. The brake control device includes a master cylinder arranged in the housing. A piston assembly includes a piston slidably disposed within the master cylinder. A brake lever is operatively coupled to the piston such that the brake lever pulls the piston from a rest position to an actuated position.

A hydraulically actuated rim brake with a pair of brake arms. Both brake arms may rotate about a common axis, which is the axis of a single bolt that mounts the assembly to the bicycle. The system has one piston slidably disposed in a piston cylinder. The piston's cylinder may be formed in one of the two brake arms. Actuation of the piston in the cylinder causes movement of both brake arms.
