Claims16
A spoked bicycle wheel comprising:
- a hub;
- a rim;
- and
- a plurality of spokes that connect the hub and the rim;
- wherein the hub has a first and a second securing portion for the spokes, mutually spaced in the direction of the longitudinal axis of the hub;
- wherein the spokes of a first set have their inner ends secured to the first securing portion and the spokes of a second set have their inner ends secured to the second securing portion;
- wherein the spokes of the first set and the second set do not cross over each other when the wheel is viewed perpendicularly to a plane through the longitudinal axis of the hub;
- and
- wherein the first and the second set of spokes each comprise a plurality of radial spokes and a plurality of non-radial spokes.

A method for the assembly of a wheel for a bicycle, comprising the steps:
- assembling a plurality of spokes that connect the hub and the rim wherein when the wheel is viewed through a cross-section through the longitudinal axis of the hub, the spokes do not each other, wherein at least one spoke is radial and one spoke is non-radial,
- undertaking preliminary centering of the wheel comprising radial spokes only,
- assembling and tensioning a plurality of non-radial spokes between the rim and the hub, and
- undertaking final tensioning of the spokes in order to achieve final centering of the wheel.
1 more element
A spoke wheel having a hub and a rim connected together by a plurality of spokes, the wheel comprising:
- an elongate hub having spaced apart first and second securing portions that define a plurality of spoke receiving apertures which are spaced circumferentially about a central axis through the hub;
- a rim having a plurality of spoke receiving apertures defined therein;
- and
- a plurality of spokes divided into first and second sets of spokes wherein the spokes of the first set are connected between the first securing portion and the rim and the spokes of the second set are connected between the second securing portion and the rim, and both the first and the second sets of spokes include spokes that are oriented radially with respect to the central axis through the hub and spokes that are oriented non-radially with respect to the central axis through the hub;
- wherein when the wheel is viewed through a cross-section through the longitudinal axis of the hub, the spokes of the first set do not cross each other and the spokes of second set do not cross each other.
