Description

technical field

[0001] The invention relates to the field of bicycle brakes, more particularly to a bicycle disc brake. Background technique

[0002] With the development of bicycle technology becoming more and more mature and people's higher requirements for green travel, bicycles are more and more used in daily life. Therefore, researchers have invested more energy in improving bicycle performance, especially on bicycle brakes. Currently used bicycle brake devices mainly include disc and drum types. Disc brakes are widely used due to their advantages such as quick response, stability and good heat dissipation. Existing disc brakes generally include A caliper operatively connected to the brake handle and a disc brake rotor fixedly connected to the hub of the wheel, wherein the disc brake rotor is connected to the hub in several ways, for example, through a bushing to the hub on the hub Corresponding splines cooperate with the connection and a locking ring to hold the brak...
