A process for manufacturing a bicycle wheel component, comprising the steps of providing a component having at least one braking area that cooperates with a braking body made by molding of composite material having structural fibers in a polymeric material, and post-molding machining of at least one region of the braking area by removing only polymeric material, without removal of the structural fiber, from the entire region so that the structural fiber outcrops at least in part from the polymeric material, and removing the structural fiber and possibly the polymeric material according to at least one groove within the region. A bicycle wheel component having a braking area of composite material, wherein in a region of the braking area, the structural fiber outcrops at least from the polymeric material, and the region comprises a groove through the structural fiber and possibly the polymeric material of the composite material.

A brake device for a vehicle with at least one wheel, wherein the wheel defines a rotational axis, with a brake body device for the transmission of a brake force to the wheel, with a concentric brake cylinder for the generation of the brake force. The brake cylinder has an inner housing part for radial support on a wheel axle of the wheel and an outer housing part for axial support on the brake body device. The two housing parts can be moved relative to one another, and a pressure chamber which runs around the rotational axis is formed between the two housing parts. The brake device has an insulation device for the thermal insulation of the brake body device in the direction of the brake cylinder. The insulation device is arranged at least axially between the outer housing part and the brake body device.

A hydraulic braking device includes an engaging base, a hydraulic brake, and a locking device. The hydraulic brake is provided on the engaging base. The locking device is adapted to fix the engaging base on a suspension fork of a bicycle, and includes a bolt and a handle, wherein the bolt passes through the engaging base to be screwed into a tapped hole of the suspension fork. The handle has a cam-shaped head pivotally connected to the bolt, and is pivotable between a first position and a second position. When the handle is located at the first position, the head presses against the engaging base to fix the engaging base on the suspension fork. When the handle is located at the second position, the engaging base is no longer being pressed against by the head, whereby the engaging base is movable relative to the suspension fork.
