An electronic device comprises a wireless transmitter and an operation device. The operation device comprises a base, a brake lever, operation portions and an electronic controller. The base is to be removably attached to a handlebar. The operation portions includes first, second and third operation portions. The first operation portion is arranged on the base. The second and third operation portions are arranged adjacent to the brake lever and are disposed between the brake lever and the handlebar. At least one of the operation portions includes a lever. At least one of the operation portions includes a button. The electronic controller is configured to transmit an operation signal to the wireless transmitter upon operation of any of the operation portions to control at least one bicycle component that is any one of a shifting device, a brake device, an adjustable seatpost, a suspension and a drive unit.

Electronic device and method for controlling electronic device

An electronic device controls at least one bicycle component in correspondence with operation of an operation device. The electronic device includes a receiver, a memory, a first wireless transmitter, a memory and an electronic controller. The receiver receives operation information corresponding to the operation of the operation device. The memory stores an actuation command of the bicycle component in correspondence with the operation information. The electronic controller receives the operation information and transmits the actuation command corresponding to the received operation information from the first wireless transmitter. The memory is configured to allow the actuation command stored in correspondence with the operation information to be changed.

A bicycle-brake-caliper attachment structure comprises a base member. The base member is configured to be coupled to a brake caliper configured to apply a braking force on a brake disc rotor configured to be rotatable about a rotational axis. The base member is configured to be attached to a bicycle frame such that relative position between the rotational axis of the brake disc rotor and the brake caliper is adjustable in a radial direction of the brake disc rotor.

Bicycle-brake-caliper attachment structure

A disc brake caliper for applying a braking force on a brake disc rotor configured to be rotatable about a rotational axis. The disc brake caliper comprises an attachment surface and a first threaded hole. The attachment surface is configured to face a pipe portion of a bicycle frame in a state where the disc brake caliper is coupled to the bicycle frame. A first thread bolt is to be inserted in the first threaded hole so as to couple the disc brake caliper to one of the bicycle frame and a base member attached to the bicycle frame, the first threaded hole being provided on the attachment surface.

Disc brake caliper and disc brake caliper assembly

A hydraulic operating device is provided. The disc brake caliper may include a brake lever pivotable on a pivot axis, a hydraulic cylinder having a cylinder axis and a reservoir arranged so as to at least partly overlap the hydraulic cylinder as seen from a first direction perpendicular to the pivot axis, the reservoir having a reservoir axis which has a different orientation than the cylinder axis as viewed from the first direction.

Bicycle hydraulic operating device

A bicycle brake caliper assembly comprises a brake caliper and a base member. The brake caliper is configured to apply a braking force on a brake disc rotor configured to be rotatable about a rotational axis. The base member is configured to be coupled to the brake caliper and to be attached to a bicycle frame such that relative position between the rotational axis of the brake disc rotor and the brake caliper is adjustable in a radial direction of the brake disc rotor. The base member includes a first coupling portion at which the brake caliper is coupled, and a second coupling portion at which the brake caliper is coupled and which is arranged apart from the first coupling portion in the radial direction.

Bicycle brake caliper assembly

A disc brake caliper comprises a caliper main-body. The caliper main-body includes a facing surface and an attachment structure. The facing surface is configured to face a mounting portion of a bicycle frame to which the disc brake caliper is attached. A connecting member is to be attached to the attachment structure. The connecting member is configured to be connected to a fluid hose. The attachment structure is provided on the facing surface.
