A spoke attachment flange for a bicycle wheel hub is disclosed. The flange has a plurality of seats for housing enlarged spoke heads. Each spoke seat has an access hole that allows the insertion of the enlarged spoke head and an outlet opening that holds the enlarged spoke head when the spoke is tensioned. The access hole and the outlet opening are spaced circumferentially and connected through a connection channel so that an abutment surface abuts the enlarged head and prevents the enlarged head from exiting through the outlet opening. Methods for manufacturing the hub and mounting a spoke on the flange are also disclosed.
