A bicycle wheel rim, comprising a wall made of composite material having a plurality of perforated spoke-attachment seats, wherein, in a single layer of unidirectional fibers, each perforated seat is delimited, at a perimeter circumference thereof, by at least one first area on the single layer comprising an amassment of continuous structural fibers and at least one second area on the single layer circumferentially spaced apart from said first area and comprising cut structural fibers, wherein the continuous structural fibers and the cut structural fibers occupy an entirety of the perimeter circumference of each perforated seat.
A bicycle wheel rim, comprising a wall made of composite material having a plurality of perforated spoke-attachment seats, wherein each perforated seat is adjacent to delimited by at least one first area comprising an amassment of continuous structural fibers and at least one second area circumferentially spaced apart from said first area and comprising cut structural fibers, wherein in areas far from the perforated seats the cut structural fibers occupy a space having, along a direction (T) perpendicular to a longitudinal direction (L) thereof, a size greater than 10% of the diameter (D) of each perforated seat.
