A process for manufacturing a bicycle wheel component, comprising the steps of providing a component having at least one braking area that cooperates with a braking body made by molding of composite material having structural fibers in a polymeric material, and post-molding machining of at least one region of the braking area by removing only polymeric material, without removal of the structural fiber, from the entire region so that the structural fiber outcrops at least in part from the polymeric material, and removing the structural fiber and possibly the polymeric material according to at least one groove within the region. A bicycle wheel component having a braking area of composite material, wherein in a region of the braking area, the structural fiber outcrops at least from the polymeric material, and the region comprises a groove through the structural fiber and possibly the polymeric material of the composite material.

An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire. The aerodynamic bicycle rim is operable to seat the bicycle tire so that the aerodynamic bicycle rim and the bicycle tire form an asymmetrical cross-sectional shape.

Disclosed are a folding wheel and a portable appliance. The folding wheel includes: a wheel body, wherein the wheel body include two wheel plates that can be spliced with each other, and a notched area is formed therebetween when the two wheel plates are spliced with each other; a first connecting element disposed in the notched area; a first slide rail mechanism, at least part of which is disposed on the first connecting element, and remaining parts of which are disposed on respective wheel plates, wherein the first slide rail mechanism includes a first rail groove and a first rotating shaft inserted into the first rail groove, such that the two wheel plates can be spliced with or separated from each other along the first rail groove via the first rotating shaft, and can be flipped relative to the first connecting element via the first rotating shaft; the folding wheel is foldable, wherein when the two wheel plates are pulled away from each other, the two wheel plates slide away from each other along the first rail groove. The two wheels may be flipped, wherein when the two wheel plates are folded towards each other, the portable appliance with reduced folded size facilitates the user to pack or carry.

A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

A mounting wheel (3) for a motor vehicle comprising an internal surface (2) and an external surface (4), the internal surface (2) not being visible when the mounting wheel (3) is mounted on the motor vehicle, and at least one fixing element (7) configured to attach the mounting wheel (3) to the motor vehicle. The fixing element (7) is arranged on the internal surface (2) of the mounting wheel (3) so that the fixing element (7) is not visible when the mounting wheel (3) is mounted on the motor vehicle.

A vehicular wheel assembly defines an axis of rotation and includes a wheel having an inner hub, an outer rim, and a plurality of hollow spokes. The outer rim defines an outer circumference. Each hollow spoke of the plurality of hollow spokes extends between the inner hub and the outer rim and includes a wall that at least partially defines a hollow chamber. The outer rim defines a plurality of openings that are each in fluid communication with one of the hollow chambers and each of the openings includes a tuning member.

A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

A wheel adapter to convert a storage container to a wheeled storage container is provided. The wheel adapter comprises a mounting bracket attachable to the storage container. The mounting bracket comprises a first leg configured to engage a bottom surface of the storage container, and a second leg configured to engage a side surface of the storage container. The second leg comprises a wheel coupling. The wheel adapter also includes a wheel rotatably connected to the wheel coupling. The wheel is constructed and arranged for rotation about an axis to provide rolling support of the storage container on the ground.
