ABSTRACT:
A strong, light weight and high performance hub is described for use in a spoked wheel in which the hub is connected to a rim by a plurality of spokes. The hub is provided with two bell-shaped end flanges which are integral. Two rings of bores are defined in each end of the flanges. The bores are paired between the rings, one bore in the outer ring being substantially adjacent to one bore in the adjacent inner ring. The angle of definition of each of the bores in the hub flange tends to orient a spoke disposed therethrough at an angle to a plane perpendicular to the longitudinal axis of the hub of about 20 degrees. When the spoke is attached to the rim, it is gently pulled or bent outward so that the angle to the plane perpendicular to the axis of the hub is reduced or in the illustrated embodiment, reduced to 9 degrees or less. The gentle bend in the spoke prevents the spoke from loosening after the initial truing and tensioning even if the spoke wheel is repeatedly subjected to high impulsive stresses. The hub also provides a light weight, strong and simple assembly for providing bearing support for an axle disposed through the hub.
