Spoke wheel

The wheel (16) has peripheral rim (17), a central hub (18) and connecting spokes (26, 27) between the rim and the hub, where the spokes are stretched. An end of the spoke is extended by an end which has a tapered central recess for receiving a screw for adjusting tension. The spokes are stretched to an initial tension corresponding to a normal tension value reduced from a value corresponding to a compression force which can be supported by each spoke. An independent claim is also included for a rolling equipment with a frame, wheels and a transmission system.
