A wheel structure having a rim and a hub interconnected by spokes with a longer portion and a shorter portion meeting at an angle or direction change region at locations all of which lie on a notional circle closer to the hub than to the rim. Preferably, the rim locations lie, in each case, beyond that radius including the spoke-hub origin point. Spurs can be provided at these locations, generally as extensions of the longer portion, to protrude into the back of the next location around the circle and thereby limit the distortion under load.
