摘要： A bicycle sprocket comprises a sprocket body, a plurality of sprocket teeth, an axially outward protuberance, and an axially inward protuberance. The axially outward protuberance is disposed on an outward facing side of the sprocket body to overlap at least partly with a bicycle chain engaging with a neighboring bicycle sprocket when viewed along a rotational center axis. The axially inward protuberance is disposed on an inward facing side of the sprocket body to overlap at least partly with the axially outward protuberance when viewed along the rotational center axis.

摘要： A bicycle chain comprises a first inner link plate comprising a first end portion, a second end portion, and a first intermediate portion. A second inner link plate is spaced apart from the first inner link plate in an axial direction. The second inner link plate comprises a third end portion, a fourth end portion, and a second intermediate portion. The first inner link plate includes a first outer surface and a first inner surface opposite to the first outer surface in the axial direction. The second inner link plate includes a second outer surface and a second inner surface opposite to the second outer surface in the axial direction. The first intermediate portion has an axial recess formed on the first inner surface in the axial direction. The second intermediate portion is free from an axial recess formed on the second inner surface in the axial direction.

摘要： A bicycle drive includes a multi-sprocket arrangement for rotatable mounting on a rear-wheel axle an engagement with a bicycle chain having inner link plate pairs and chain outer link plate pairs. The multi-sprocket arrangement includes a sprocket having, between an axial inner side and an oppositely situated axial outer side, a flat sprocket body and a plurality of teeth formed on a circumference of the sprocket. The plurality of teeth include at least one tooth of a first tooth group, the axial width of which is dimensioned to be greater than a chain inner link plate spacing and smaller than a chain outer link plate spacing, and a second tooth group, the axial width of which are dimensioned to be smaller than the chain inner link plate spacing.

摘要： A bicycle sprocket comprises a sprocket body, sprocket teeth, and at least one shifting facilitation area. The sprocket teeth include at least one first tooth and at least one second tooth. The at least one first tooth includes a first tooth center plane defined to bisect a first maximum axial width. The at least one second tooth includes a second tooth center plane defined to bisect a second maximum axial width. The second tooth center plane is offset from the first tooth center plane in an axial direction. The at least one shifting facilitation area is configured to facilitate a shifting operation of the bicycle chain.

摘要： A bicycle front sprocket assembly is basically provided with a first sprocket, a second sprocket, a sprocket carrier and a chain guiding portion. The first sprocket includes a first sprocket body and a plurality of first sprocket teeth disposed on a first outer periphery of the first sprocket body, The second sprocket includes a second sprocket body and a plurality of second sprocket teeth. The second sprocket teeth are disposed on a second outer periphery of the second sprocket body. The sprocket carrier includes a torque transmitting profile and a sprocket mounting portion. The chain guiding portion is positioned between the first and second sprockets in an axial direction parallel to a rotational center axis of the bicycle front sprocket assembly. At least one of the first and second sprockets is mounted to the sprocket mounting portion of the sprocket carrier by a non-threaded fastener.

摘要： A bicycle sprocket assembly comprises a first sprocket and a second sprocket. The first sprocket comprises a first sprocket body, a first shifting facilitation area, a plurality of first chain-driving teeth, and a first outer diameter. The second sprocket comprises a second sprocket body, a plurality of second chain-driving teeth, a second outer diameter, and a support protuberance. The support protuberance protrudes from the second sprocket body toward the first sprocket. The support protuberance is provided in a circumferential support area on the second sprocket. The circumferential support area is configured to face a circumferential area on the first sprocket in an axial direction. The circumferential area extends from a third tooth to a fifth tooth in a circumferential direction with respect to a rotational center axis.

摘要： A bicycle derailleur comprising a chain guide, an electric motor that displaces the chain guide and an electrically controllable device configured to, selectively, block the rotation of the electric motor and let the electric motor free to rotate. A method for actuating a bicycle derailleur comprising a chain guide and an electric motor that displaces the chain guide, comprises the steps of: receiving a gearshifting request signal; making the electric motor free to rotate; driving the electric motor to displace the chain guide until the chain guide is in an intended position while the electric motor is made free to rotate; and, blocking the rotation of the electric motor.
