摘要： A bicycle hub 1 includes a hollow cylindrical body 3 which is provided with external splines having teeth 5 extending in axial direction. Each tooth has a first axial side 7 which is loaded during use by a sprocket wheel slid onto the body and an opposite, second axial side 9. Three of the teeth are composed of two portions, that is to say a first portion 11 which forms a whole with the body and a second portion which forms an insert 13. The insert partly forms the first side 7 of the tooth. The body is provided with three axial grooves 15 which accommodate the inserts 13. The inserts 13 partly protrude above the grooves and the height 17 of the inserts is approximately equal to the width 19 of the inserts.

The chain engagement structure is arranged on a radially outer periphery of the sprocket body. The chain engagement structure includes at least one shifting facilitation area and a plurality of chain-engaging teeth. The at least one shifting facilitation area is configured to facilitate changing gears. The plurality of chain-engaging teeth include at least two neighboring chain-engaging teeth each including a chain-engaging portion configured to engage with a bicycle chain. The chain-engaging portion has an axial chain-engaging width defined in the axial direction. The axial chain-engaging width is larger than the axial width of the sprocket body.

摘要： A multiple sprocket assembly for receiving a chain and transferring torque therefrom to a bicycle rear wheel hub rotatable about a hub axis. The chain has alternating pairs of inner and outer link plates connected by chain rollers. The multiple sprocket assembly includes a plurality of different-sized sprockets arranged coaxially about the rear wheel hub. The sprockets have a plurality of teeth and tooth roots spaced around a periphery of the sprockets for engaging the chain. The tooth roots forming a dedendum circle. The sprockets have a maximum sprocket width near the dedendum circle, substantially bridging a gap between paired inner link plates sandwiching the chain roller therebetween, substantially minimizing axial play between a guide area on the sprocket and an overhang of the inner link plates overlapping the guide area when the chain is engaged with the sprockets.

摘要： A sprocket mounting carrier has a cylindrical body which on the outside is provided with grooves extending in axial direction. The sprocket mounting carrier has such a shape that both sprockets of a first type and sprockets of a second type can be slid onto it. These sprockets each have a central hole whose bounding wall has cams. The bottoms and side walls of the grooves of the sprocket mounting carrier, in the event of sprockets being present on the sprocket mounting carrier, engage with the cams of the sprockets, so that the sprockets are secured to the sprocket mounting carrier both in radial direction and in tangential direction.

摘要： A sprocket assembly mounted to a hub has at least eleven sprockets. The hub is able to rotate about a rotation axis and has a plurality of spoke attachment seats and a fastening portion to a frame of the bicycle. On the hub a predetermined axial distance is defined between a plane, substantially perpendicular to the rotation axis, comprising the points of the spoke attachment seats closest to the freewheel body and a plane, substantially perpendicular to the rotation axis and defined in the fastening portion to the frame, comprising the attachment points to the frame closest to the freewheel body. All of the sprockets of the sprocket assembly, when associated with the freewheel body, have an overall axial width that is lower than or equal to the predetermined axial distance. The chain has a maximum thickness between 4.6 mm and 5.8 mm.

摘要： A bicycle sprocket assembly has a first sprocket with a plurality of first radially protruding portions, a second sprocket with a plurality of second radially protruding portions and a sprocket support member. The second sprocket has more teeth than the first sprocket. The sprocket support member includes a plurality of sprocket mounting portions extending radially outwardly from a freewheel engaging portion. Each of the sprocket mounting portions has first and second sprocket mounting openings for fixing the first and second sprockets, respectively. The first sprocket mounting opening is circumferentially offset from the second sprocket mounting opening with respect to a center rotational axis of the sprocket assembly. The radially innermost edge of the second radially protruding portion is spaced by a radial distance that is smaller than a radial distance of the radially outermost edge of the first sprocket mounting openings with respect to the center rotational axis.
