Adjacent spokes (3) reach from the center (5) of the wheel to its outer edges (4). They include projecting ribs (7, 8) forming stress-transmission paths (F1, F2) running to the wheel fastener (20). The rib projections (7, 8) are bordered by depressions (9, 10, 11) running along their length. They are connected to the wheel center (5) by enlarged-area nodes (A1, A2).
