An operating device is provided for a human-powered vehicle. The operating device basically includes a base, a first operating member, a first electric switch, a first load generator and an operating load adjuster. The first operating member is movably arranged with respect to the base. The first electric switch is provided to the base and arranged to be activated by movement of the first operating member. The first load generator is configured to generate an operating load applied to the first operating member. The operating load adjuster is configured to adjust a transition of the operating load from a first load transition to a second load transition different from the first load transition.

A hydraulic one-finger two-way acting gear shift operator for a handlebar includes a housing with first and second cylinder chambers, a first and a second piston with first and second piston rods arranged in the first and second cylinder chambers, a first and a second lever arranged to independently push the first and second piston rods and corresponding pistons longitudinally inside the first and second cylinder chambers, wherein the first and second levers are connected to the housing in first and second pivot points, respectively.

A bicycle head is configured to be mounted on a bicycle frame. The bicycle head includes a vertical tube, a stem, a handlebar, a first brake lever, and a shift control box. One end of the stem is mounted on the vertical tube. The handlebar is fixed to another end of the stem. The first brake lever assembly is mounted on the handlebar. The first brake lever assembly includes a main body, a brake assembly, a shift switch, and a battery. The brake assembly and the battery are disposed on the main body, and the shift switch is disposed on the brake assembly. The shift control box is disposed on one of the vertical tube, the stem, and the handlebar and electrically connected to the battery and the shift switch.

The invention relates to a dynamic force-distributing device. The dynamic force-distributing device has a dynamic three-stage force distribution function, and is especially suitable for being applied to a single-handed braking device of various front and rear wheel form vehicles. The whole braking process can show three-stage functional characteristics such as safety, stability, reliability, fast stopping and the like, so that the problem of accidents caused by improper brake operation is avoided.

A brake disc having a first component made of a first material, a braking track configured to cooperate with brake pads, and a second component made of a second material and having (i) a radially inner annular portion for coupling with a hub of a bicycle wheel and (ii) a plurality of radially outer portions for connecting to said first component at a respective plurality of connection portions of said first component. The first component comprises a plurality of connection arms that extend from said braking track towards said predetermined rotation axis (X) and that are distinct from said plurality of connection portions, wherein at least one of said connection arms of said first component and at least one of said radially outer connection portions of said second component are coupled together through at least one shape coupling.

A front derailleur actuation device having a cable-winding bush in a casing rotatable about axis (X) in a first angular direction (A) between a first angular position and a last two angular positions to actuate a member mounted rotatable about axis (X) and a stationary member mounted in the casing. Either the rotating member or the stationary member is provided with at least one pointer slidably engaged on a fastening track equipped with a plurality of stop areas provided on the other member. The stationary member or the rotating member provided with the fastening track further comprises at least one further stop area not arranged along the fastening track, said further stop area being engageable by the pointer and being arranged between two successive stop areas of said fastening track, the cable-winding bush passing between two angular positions following the passage of the pointer between two stop areas.

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.
