A laced wheel manufactured from a one-piece casting, including both the hub portion and the rim portion. After casting and machining spoke interfaces, the hub and rim portions are separated and wire spokes are assembled.

An assembly device for assembling an airless tire (2) that comprises a hub (3) having a central axis (Z3), a peripheral annular band (4) and a plurality of spokes (5) that connect the hub (3) to the peripheral annular band (4), comprises a plurality of pressing sub-assemblies (10) each comprising pushers (11, 12) to press the ends (6, 7) of the spokes (5) against the hub (3) and against the peripheral annular band (4), respectively, as well as a punch (13) that is mounted movably in axial translation parallel to the central axis (Z3), and provided with ramps (15, 16) arranged so that the axial movement of the punch causes the pushers (11, 12) to move radially.

A device for assembling an airless tire (2) comprising a hub (3) of central axis (Z3), a peripheral annular band (4) and a plurality of spokes (5) that connect the hub (3) to the peripheral annular band (4) comprises a plurality of pressing sub-assemblies (10) each comprising pushers (11, 12) for pressing the feet (6, 7) of the spokes (5) against the hub (3) and the peripheral annular band (4) respectively, as (20) and each hold a lever (15, 16) that makes it possible to transmit a clamping force (F15, F16) to the pusher (11, 12) while ensuring elastic radial suspension of the pusher (11, 12) vis--vis the traveller (13, 14) and therefore against the foot (6, 7) of the spoke and the hub (3) or the peripheral annular ring (4) well as travellers (13, 14) that are mounted radially movably under the control of a drive system respectively.

A cassette for a bicycle may include a plurality of sprocket portions joined together into a single unit. The cassette may include a cavity formed in the large end of the cassette. A related manufacturing method may include joining a first generally planar sprocket portion having a plurality of connector portions extending transverse to the plane of the first sprocket portion, to a second generally planar sprocket portion, e.g., by fusing at least one of the connector portions to the second sprocket portion.

A spoked wheel truing system includes a client computer configured with a graphical user interface to collect data on a wheel. The client computer is configured to communicate with a remote server to send the collected data to the remote server, and receive from the remote server processed data comprising instructions on truing the wheel.
