The rim has an orifice that is drilled in a lower bridge (5) by upsetting process and is limited by a shaft (15). The length of the shaft is three times the initial thickness of the lower bridge. An insert (18) provided for being screwed in the orifice has a hexagonal section at its lower part. An end piece (28) integrated at end of a spoke (25) has a hexagonal section that cooperates with the hexagonal section of the insert. An independent claim is also included for a wheel comprising a central hub, a rim and spokes.
