A bicycle wheel securing structure includes a bicycle fork, an adapter and a holding member. The bicycle fork has two axle support portions that are spaced apart for receiving a bicycle hub therebetween. The adapter is disposed in an adapter receiving bore in one of the axle support portions. The adapter includes a threaded axle mounting opening. The holding member is operatively coupled between the adapter and the one of the axle support portions with the adapter. The holding member prevents both rotational movement of the adapter with respect to the bicycle fork and axial movement of the adapter with respect to the bicycle fork along an axis of the axle mounting opening when the holding member is in a retaining position. The adapter is rotatable within the adapter receiving bore without moving axially with respect to the bicycle fork when the holding member is in a releasing position.

A bicycle hub is provided that comprises a hub axle, a hub body rotatably mounted on the hub axle by a pair of bearings. The bicycle hub also has an inner tubular structure including a pair of inner tubes. One of the inner tubes is fixedly secured relative to a first body end adjacent to a first bearing, while the other inner tube is fixedly secured relative to the second body end adjacent to the second bearing. The inner tubes have inner free end portions that are telescopically arranged so that the inner tubes can be used with several different has that have different axial widths.

A bicycle wheel securing structure includes an outer axle, an inner axle, a head member and a lever member. The outer axle has a first threaded end and a second end. The inner axle is coupled to the outer axle within an internal bore of the outer axle. The head member is disposed on the inner axle with the lever member operatively mounted to move the head member relative to the inner axle in response to movement of the lever member. A structure is arranged such that a final rotational position of the lever member can be adjusted. A structure is also disposed between the outer axle and the inner axle to releasably prevent axial removal of the inner axle from the internal bore of the outer axle.

A bicycle hub includes a hub axle, a hub body, a bearing unit and a lock member. The hub axle is configured and arranged to be non-rotatably coupled to the bicycle frame by a mounting shaft. The hub body has a generally cylindrical shape mounted adjacent to an external perimeter of the hub axle. The bearing unit is installed between the hub body and the hub axle at one axial end portion of the bicycle hub so that the hub body freely rotates with respect to the hub axle. The bearing unit includes an outer ring, an inner ring and a plurality of rolling components. The lock member is configured and arranged to retain an axial position of the outer ring of the bearing unit with respect to the hub body by locking the outer ring in one of a plurality of rotational positions.

A rear hub has a hub shaft and a hub outer that is configured to be mounted in a freely rotatable manner to the hub shaft. The hub outer has an outer main body and an adapter. The outer main body is arranged on the radially inward side of a sprocket, and has a first rotation preventing section that engages with an engaging section 64 of the sprocket in such a manner that the outer main body cannot rotate relative to the sprocket. The adapter is mounted in a freely rotatable manner on an adapter mounting section of the outer main body. The adapter includes a second rotation preventing section that engages with the engaging section of the sprocket in such a manner that the adapter cannot rotate relative to the sprocket.

A bicycle disc brake hub is basically provided with a hub axle and a hub shell rotatably disposed about the hub axle. The hub shell has a pair of flanges with a tubular portion extending between the flanges, and a rotor attachment portion configured to prevent an inside diameter of a disc brake rotor from increasing when the diameter of the hub axle increases. The rotor attachment portion is provided in the vicinity of a first shell end of the hub shell, and has a smaller outside diameter than the outside diameter of the tubular portion. A rotor of a disc brake device is attached to the rotor attachment portion.

An easily mountable disc brake rotor assembly that is lightweight is provided. The bicycle disc brake rotor assembly includes a rotor and an adaptor and is mounted to the front hub of a bicycle. A caliper mounted to the bicycle's suspension fork grips the rotor. The rotor is a ring-shaped plate, which has brake surfaces that are gripped by the caliper. The adapter is mounted to the front hub and has a deformation that secures the rotor to the hub. External and internal splines on the adapter prevent the rotor from rotating and transmit a braking force exerted on the rotor to the hub, respectively.

A bicycle hub is provided that includes a hub axle, a hub body, a sprocket support member and a spacer. The spacer is movable to allow the hub body to be axially separated from the freewheel without removing the freewheel from the rear fork of the bicycle. The hub axle has a first portion and a second portion releasably coupled to the first portion. The hub body has an outer tubular portion and an interior passageway with the first portion of the hub axle rotatably supported therein. The sprocket support member has a portion releasably and non-rotatably coupled to the outer tubular portion of the hub body. The sprocket support member is mounted on the second portion of the hub axle. The spacer is supported on the first portion of the hub axle adjacent a free end of the hub body. The spacer has a spacing portion and is configured to move in a transverse direction relative to the hub axle between a first position and a second position without removing the first portion of the hub axle from the hub body. In the first position, the spacing portion is located adjacent the hub axle. In the second position, the spacing portion is spaced from the hub axle.

A bicycle hub is provided with a hub axle, a hub shell, a freewheel, a first hub axle ball bearing and a second hub axle ball bearing. The freewheel is operatively mounted between the hub axle and the hub shell. The freewheel includes a driven member, a drive body, an inner freewheel ball bearing and an outer freewheel slide bearing. The driven member is fixed to the hub shell to rotate therewith, while the drive body is operatively coupled to the driven member by a one-way clutch mechanism. The inner freewheel ball bearing is disposed between the driven member and the drive body to rotatably support an inner end of the drive body on the driven member. The outer freewheel slide bearing is disposed between the driven member and the drive body to rotatably support an outer end of the drive body on the driven member.

A sprocket is adapted to be mounted to a sprocket support that rotates around an axle. The sprocket comprises a sprocket body having a side surface and an inner peripheral surface defining a sprocket-mounting opening, wherein at least one portion of the inner peripheral surface is adapted to contact the sprocket support. At least one lateral projection extends laterally from the side surface of the sprocket body in close proximity to the at least one portion of the inner peripheral surface that is adapted to contact the sprocket support.
