Abstract
A bicycle hub system, method and device including rear and front hub assemblies. Both the rear and front hub assemblies include locking mechanisms with matching undulating splined coupling faces that correspond to complementary undulating splined coupling faces of a wheel hub.
Claims30
A bicycle rear hub system including a direct mount derailleur, the system comprising:
- a rear locking mechanism including a derailleur mounting base having a pair of mounting arms, derailleur coupling housing, a derailleur bearing, a wave face axle and a rotor mount housing, the wave face axle having a splined head face, the rotor mount housing having a splined housing face and each of the mounting arms having a mounting aperture, wherein the derailleur coupling housing is positioned at least partially through both of the mounting apertures and the derailleur bearing is positioned around a hollow shaft of the wave face axle within the derailleur coupling housing such that the wave face axle is able to rotate within the derailleur coupling housing;
- a rear hub positioned between the splined housing face and the splined head face;
- and
- a through axle positioned through the derailleur coupling housing, the wave face axle and a central channel of the rear hub, the through axle being detachably coupled within a central aperture of the rotor mount housing;
- wherein when the rear locking mechanism is coupled to the rear hub, the wave face axle rotates with the rear hub as the rear hub rotates about the through axle.

A rear hub locking mechanism including a direct mount derailleur, the mechanism comprising:
- a derailleur mounting base having a pair of mounting arms, the mounting arms each including a mounting aperture, wherein the mounting apertures are aligned so as to share a central axis;
- a derailleur coupling housing positioned at least partially through both of the mounting apertures;
- a derailleur bearing;
- a wave face axle having a splined head face, wherein the derailleur bearing is positioned around a hollow shaft of the wave face axle within the derailleur coupling housing such that the wave face axle is able to rotate within the derailleur coupling housing;
- and
- a rotor mount housing having a splined housing face.

A method of operating a bicycle rear hub system including a direct mount derailleur, the method comprising:
- providing a rear locking mechanism including a derailleur mounting base having a pair of mounting arms, derailleur coupling housing, a derailleur bearing, a wave face axle and a rotor mount housing, the wave face axle having a splined head face, the rotor mount housing having a splined housing face and each of the mounting arms having a mounting aperture, wherein the derailleur bearing is positioned around a hollow shaft of the wave face axle within the derailleur coupling housing such that the wave face axle is able to rotate within the derailleur coupling housing;
- positioning the mounting arms on either side of a rear fork end of a bicycle frame such that the mounting apertures align with a hole in the rear fork end;
- sliding the derailleur coupling housing at least partially through the hole and both of the mounting apertures;
- positioning a rear hub between the splined housing face and the splined head face;
- sliding a through axle through the hollow shaft of the wave face axle, the hole, the mounting apertures, the derailleur coupling housing and a central channel of the rear hub;
- and
- detachably coupling the axle within a central aperture of the rotor mount housing.
