Brake rotors for bicycles are described herein. An example brake rotor for a bicycle includes a carrier to be coupled to a hub of the bicycle. The brake rotor also includes a brake track having braking surfaces to be engaged by brake pads. The brake track is disposed radially outward of the carrier. The brake track has a first thickness and the carrier has a second thickness greater than the first thickness. The brake track is coupled to the carrier such that the brake track is axially movable relative to the carrier while being radially and circumferentially constrained relative to the carrier.

In some examples, a drive insert comprises a first clip, a second clip, and a retainer. The first clip is configured to be slidable over a first surface adjacent to a first drive slot of a brake disc in a first tangential direction of the brake disc. The second clip is configured to be slidable over a second surface adjacent to a second drive slot of the brake disc in a second tangential direction of the brake disc. The retainer is configured to be slidable over the first clip and the second clip when the first clip and second clip are positioned one the brake disc secure the first and second clips to the brake disc.

A wheel and brake assembly comprising: a stator; a rotating assembly mounted around and rotatable relative to the stator about an axis A; a torque tube in fixed engagement with the stator; a stack of brake disks mounted about the torque tube, the stack of brake disks comprising alternate rotor disks and stator disks, the stator disks attached to the torque tube and the rotor disks attached to the rotating assembly; a brake actuator configured to, in response to a brake command, apply a pressing force on the stack of brake disks to cause frictional engagement between the rotor disks and the stator disks such that the stator disks prevent the rotor disks and, hence the rotating assembly, from rotating relative to the torque tube.

A hub configured to rotate about an axis of rotation in the circumferential direction, and having a connection surface and a connection opening, the connection opening configured to at least partially receive a connector, the connection surface configured to contact indirectly and/or directly with a contact surface of a brake disc, where the contact surface does not include connection openings.

An anti-lock sensor ring may have a flattened exciting portion having a retention mechanism projecting from a ring radial edge. The retention mechanism may have cantilever spring retention clips elastically deformable to snap on a disc brake band retention seat. The mechanism may also have a cantilever support portion disposed side by side to and spaced apart from the cantilever spring retention clips. Each of the cantilever spring retention clips may have a retention surface and the cantilever support portion with a support surface. When the anti-lock sensor ring is dismounted from a disc brake band, the plane defined by the retention surface and the plane defined by the support surface are facing each other in order to create opposing gripping elements.

In some examples, a drive insert comprises a first clip, a second clip, and a retainer. The first clip is configured to be slidable over a first surface adjacent to a first drive slot of a brake disc in a first tangential direction of the brake disc. The second clip is configured to be slidable over a second surface adjacent to a second drive slot of the brake disc in a second tangential direction of the brake disc. The retainer is configured to be slidable over the first clip and the second clip when the first clip and second clip are positioned one the brake disc secure the first and second clips to the brake disc.

A wheel brake arrangement for a wheel of a vehicle, said wheel brake arrangement comprising a wheel hub (102) comprising an outwardly facing gear teeth arrangement (104) arranged in a circumferential direction thereof; and a brake disc (106) comprising an inwardly facing gear teeth arrangement (108) arranged in meshed connection with the outwardly facing gear teeth arrangement of the wheel hub for preventing a relative circumferential movement between the brake disc and the wheel hub, wherein one of the wheel hub and the brake disc comprises a circumferentially arranged groove (110); wherein the wheel brake arrangement further comprises at least one retainer (112) connected between the wheel hub and the brake disc for preventing a relative axial movement between the wheel hub and the brake disc, wherein the at least one retainer is at least partially arranged in the circumferentially arranged groove (110) of one of the wheel hub and the brake disc.

A disc brake rotor includes an annular portion having a first surface and a second surface in opposition to the first surface. The first surface and second surface traverse a periodic wave. An inner radial edge of the annular portion traverses an inner periodic wave and an outer radial edge of the annular portion traverses an outer periodic wave. A pattern and a period are the same for the periodic wave, the inner periodic wave, and the outer periodic wave. Thermal radiation elements are coupled to portions of at least one of the inner radial edge and the outer radial edge.

A braking arrangement includes a torque plate, a torque button, and a sacrificial bushing. The torque button comprises a head portion and a shaft portion, wherein the head portion is configured to extend at least partially into a torque pocket of an end plate of a brake stack and the shaft portion is configured to extend through an aperture disposed in a back leg of the torque plate. The bushing is configured to be removably coupled between the shaft portion of the torque button and the back leg of the torque plate.

A hybrid torque bar for a brake assembly may comprise a base portion, a pin extending from a first end of the base portion, and a rail extending between the first end of the base portion and a second end of the base portion opposite the first end. The base portion may be formed using a first manufacturing process. At least one of the pin or the rail may be formed using a second manufacturing process. The second manufacturing process may comprise an additive manufacturing technique.
