Abstract: A hydraulic braking system includes a base, which has an oil chamber and a connecting hole communicating with each other, a seat, which is provided in the oil chamber and has a receiving space communicating with the oil chamber and the connecting hole, a check valve movably provided in the receiving space and the connecting hole, and an elastic member. When one end of a connecting pipe which is connected to a brake actuator is inserted into the connecting hole to engage the base, the check valve is pushed inward to inject the hydraulic fluid in the oil chamber into the connecting pipe; when the connecting pipe is detached from the base, the check valve is pushed by the elastic member, and therefore returns to the original position. Whereby, the hydraulic fluid is prevented from leaking out.

Abstract: A bicycle rear derailleur is provided, which includes a base adapted to be mounted on a bicycle frame, a movable member, a linkage assembly pivotally connected to and between the base and the movable member, a pivot shaft provided within and pivotally rotatable relative to the movable member, a chain guide fixed to an end of the pivot shaft, a restriction assembly provided on the pivot shaft, and a friction assembly provided within the movable member to provide a rotational friction on the restriction assembly. Whereby, the chain guide is pivotally awing toward a first direction by a force; when the chain guide swings toward a second direction which is opposite to the first direction by another force, it is forced by a swing resistance.

Abstract: A disc brake caliper of a bicycle includes a main body, a first bolt, an intermediate member, a second bolt, and a tubing connector. The main body has an oil passage and a first tapped hole communicating with the oil passage. The first bolt is screwed into the first tapped hole, with a first exposed section exposed out of the main body. The intermediate member fits around the first exposed section through a first perforation, and has a second tapped hole, which extends in a direction different from that of the first perforation. The intermediate member can be rotated relative to the first exposed section. The second bolt is screwed in the second tapped hole, with a second exposed section exposed out of the intermediate member. The tubing connector fits around the second exposed section through a second perforation, and can be rotated relative to the second exposed section.

Abstract: 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.

Abstract: A quick release device for bicycle wheel is disclosed, including a mandrel, a wrench, at least one key, a limiting member, and an elastic member. The mandrel includes a shaft and an axial sleeve positioned at one terminal of the shaft and formed with multiple first grooves. The wrench includes a sleeve mounted on the axial sleeve, and is movable between a first position and a second position. The sleeve includes at least one second groove, wherein the key is positioned within one of the first grooves and the second groove when the sleeve is at the first position; the key is apart from one of the first grooves when the sleeve is the second position. The limiting member fits around the mandrel and includes a stopper. The elastic member is between the key and the stopper. Whereby, the application strength and lifetime can be increased with a lightweight feature.
