The at least one first tooth has a first circumferential tooth-length defined in a circumferential direction at a radial location defined in vicinity of a reference line. The at least one second tooth has a second circumferential tooth-length defined in the circumferential direction at the radial location. The first circumferential tooth-length is larger than the second circumferential tooth-length. A dimensional difference between the first circumferential tooth-length and the second circumferential tooth-length is equal to or smaller than 1 mm.

摘要： A bicycle transmission apparatus comprises a base member, a first transmission member, a second transmission member, and a first coupling member. The first transmission member is rotatable relative to the base member about a first rotational axis and is movable relative to the base member in an axial direction parallel to the first rotational axis. The second transmission member is rotatable relative to the base member about a second rotational axis and is stationary relative to the base member in the axial direction. The first coupling member is configured to couple the first transmission member to the second transmission member to transmit rotation of the first transmission member to the second transmission member at a variable speed stage which is variable in accordance with at least one positional relationship among the first transmission member, the second transmission member, and the first coupling member in the axial direction.

摘要： A rear derailleur is basically provided with a base member, a movable member, a chain guide, a friction element, a one-way clutch and an electric actuator. The base member is configured to be mounted to a bicycle. The movable member is movably coupled to the base member. The chain guide is coupled to the movable member to rotate around a rotational axis with respect to the movable member. The friction element is operatively arranged between the movable member and the chain guide to frictionally provide rotational resistance in a first rotational direction of the chain guide. The one-way clutch is operatively disposed between movable member and the chain guide to engage the friction element as the chain guide rotates in the first rotational direction. The electric actuator is operatively coupled to the one-way clutch to control the one-way clutch between a clutch-on mode and a clutch-off mode.

摘要： A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, and a clutch. The sprocket support body is rotatably mounted on the hub axle to rotate about a rotational axis. The sprocket support body is rotatable relative to the hub axle and the hub shell about the rotational axis. The clutch has a first coupling state where a pedaling rotational force is transmitted from the sprocket support body to the hub shell in a first rotational direction during pedaling, a first release state where the hub shell is rotatable relative to the sprocket support body in the first rotational direction during coasting, and a second coupling state where a coasting rotational force is transmitted from the hub shell to the sprocket support body in the first rotational direction during coasting.

摘要： A bicycle derailleur includes a base member, a movable member, a motor unit, a linkage and a saver mechanism. The linkage includes a first link that includes a first linking member and a second linking member. The first linking member is pivotally connected to the movable member. The second linking member is pivotally connected to the base member, and is attached to the first linking member. The saver mechanism includes an output member movably operated by the motor unit, a drive link movably mounted on the first link between a drive transmitting position that connects a drive force of the motor to the first link and a non-drive transmitting position that disconnect the drive force of the motor from the first link, and a biasing element biasing the drive link into engagement with the output member to maintain the drive link in the drive transmitting position.

摘要： A bicycle rear derailleur includes a base element including a first attachment end for coaxial installation on a rear-wheel axis and a second attachment end, a movable element movable relative to the base element, a linkage mechanism connecting the movable element to the base element, and a chain guide arrangement rotatably connected to the movable element. The second attachment end is coupled to the linkage mechanism. The first attachment end includes a first arm and a second arm, which are spaced apart in an axial direction with respect to the rear-wheel axis. The base element includes an angular position adjustment structure that adjusts an angular position of the derailleur relative to a bicycle frame by rotating the first arm and the second arm about the rear-wheel axis. The angular position adjustment structure is disposed between the first and second attachment ends in a radial direction of the rear-wheel axis.
