Abstract: A bicycle cable assembly mainly includes an external protection tube composed of several hollow sleeves hooking together. Hooks and engaging edges of the sleeves hook together so that the external protection tube is formed and can be properly adjusted according to a length of a cable and a special position by increasing or decreasing the number of sleeves. Also, the hook hooking the engaging edge can prevent the external protection tube from being arbitrarily disassembled by others. Also, it is possible to effectively prevent an inner protection tube from exposing to the outside and thus being damaged. Thus, a protection layer can be indirectly added to the bicycle cable assembly.

Abstract: A hydraulic brake lever for a bicycle, comprising a main body, a pull handle, and an adjusting mechanism. Thus, the hydraulic brake lever can be operated conveniently and smoothly, thereby facilitating the rider operating the hydraulic brake lever. In addition, the hydraulic brake lever is sensitive, thereby protecting the rider's safety. Further, the operation stroke of the brake can be changed and adjusted conveniently, so as to adjust the sensitivity of the brake to the optimum state.

Abstract: A hydraulic brake device for a bicycle includes a hydraulic brake having a first recess and a second recess, and a conduit wire connected to the triple body of the hydraulic brake. The triple body has an inside provided with an inlet tube connected to the conduit wire, a first tube connected to the inlet tube and the first channel of the first recess, and a second tube connected to the inlet tube and the second channel of the second recess. Thus, the hydraulic brake device can provide a braking effect gradually, without incurring a self-locking action, thereby protecting the rider's safety.
