The invention relates to a spoke-attachment flange for a hub for a bicycle wheel. The flange comprises an annular body made of a composite material and extending coaxially to a rotation axis (X). The annular body (121) is obtained by compression molding from a semi-finished product (220) and comprises a radially outer annular portion (121a) including a plurality of unidirectional structural fibers incorporated in a polymeric material and oriented along a substantially circumferential direction, a plurality of seats configured to house enlarged heads of spokes and a plurality of interconnection areas devoid of said seats, each of said interconnection areas being circumferentially arranged between two respective seats. The radially outer annular portion (121a) includes, at each of said seats, a number of radially juxtaposed layers (221a) of a strip (221) of said unidirectional structural fibers greater than the number of layers (221b) of said strip (221) of said unidirectional structural fibers provided at each of said interconnection areas.
