Abstract
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.
Claims19
A bicycle control device for use with a road bicycle, the bicycle control device comprising:
- a housing configured to be attached to a handlebar of the road bicycle, the housing including a first side and a second side;
- and
- a hydraulic brake control device including:
- a master cylinder arranged in the housing,
- a piston assembly including a piston slidably disposed within the master cylinder,
- a brake lever operatively coupled to the piston such that the brake lever pulls the piston from a rest position to an actuated position, and
- an outlet passageway in fluid communication with hydraulic cylinder and extending between a first opening on the first side of the housing and a second opening on the second side of the housing,
- wherein the hydraulic brake control device further includes a tube connected to, and in fluid communication with, the outlet passageway at a first end of the tube, the tube including a hydraulic fitting on a second end of the tube.
