Abstract
A bicycle rim comprising a circumferential outer portion adapted to receive a tire and a spoke bed. The spoke bed may comprise a pattern of spoke attachment segments at varying tilt angles and spaced by intermediate segments. Each spoke attachment segment may comprise an inner surface, an outer surface and a spoke opening extending from the inner surface to the outer surface. The spoke opening may be sized to accommodate a spoke nipple. The spoke opening may have a central axis angled at a complex angle that is a combination of a respective camber angle and a respective crossing angle. The complex angle may be selected to achieve a respective spoke angle. The outer surface of the spoke attachment segment adjacent to the spoke opening may extend perpendicular to the central axis of the spoke opening.
