Abstract: The present invention relates to a toothed belt wheel (1), in particular for bicycles or motorcycles, for torque transmission from the crankshaft or engine shaft to the rear wheel. The toothed belt wheel (1) consists of individual disc-shaped elements (2, 3, 4; 10, 11, 12), which are fixedly connected to one another to form a unit. The toothed belt disc (9) of the toothed belt wheel (1), which is intended for the engagement of a toothed belt, is assembled from at least two elements (2, 3; 10, 11), specifically a carrier disc (2) and one or more tooth discs (4). In addition, a flanged disc (3) can also be arranged on the toothed belt disc (9).
