ABSTRACT:
A hub for a spoked wheel includes an annular peripheral portion having an outer surface, an inner surface, and a peripheral edge, wherein the inner surface and the outer surface define non-parallel planes, and wherein the inner surface forms an acute angle with respect to the rotational axis defined by the hub, whereby the peripheral portion is thickest along the peripheral edge, and tapers to a reduced thickness at a constant radius from the peripheral edge. First and second pluralities of spoke attachment apertures extend through the outer and inner surfaces, the first plurality of spoke attachment apertures providing attachment points for a plurality of outer spokes on the outer surface and the second plurality of spoke attachment apertures providing attachment points for a plurality of inner spokes on the inner surface. First and second pluralities of grooves on the outer and inner surfaces, respectively, are each dimensioned to receive and engage a portion of the length of one of the spokes adjacent its associated attachment point so as to substantially reduce the pivoting of the spoke around its associated attachment point in response to a torque applied to the spoke.
